# Changelog
## v3.1.1 - 2019-01-11
- testfixtures now work with both `mssql` and `sqlserver` drivers.
Note that [the `mssql` one is deprecated](https://github.com/denisenkom/go-mssqldb#deprecated),
though. So try to migrate to `sqlserver` once possible.
## v3.1.0 - 2019-01-09
- Using `sqlserver` driver instead of the deprecated `mssql`
([#58](https://github.com/go-testfixtures/testfixtures/pull/58)).
## v3.0.0 - 2019-12-26
### Breaking changes
- The import path changed from `gopkg.in/testfixtures.v2` to
`github.com/go-testfixtures/testfixtures/v3`.
- This package no longer support Oracle databases. This decision was
taken because too few people actually used this package with Oracle and it
was the most difficult to test (we didn't run on CI due the lack of an
official Docker image, etc).
- The public API was totally rewritten to be more flexible and ideomatic.
It now uses functional options. It differs from v2, but should be easy
enough to upgrade.
- Some deprecated APIs from v2 were removed as well.
- This now requires Go >= 1.13.
### New features
- We now have a CLI so you can easily use testfixtures to load a sample
database from fixtures if you want.
- Templating via [text/template](https://golang.org/pkg/text/template/)
is now available. This allows some fancier use cases like generating data
or specific columns dynamically.
- It's now possible to choose which time zone to use when parsing timestamps
from fixtures. The default is the same as before, whatever is set on
`time.Local`.
- Errors now use the new `%w` verb only available on Go >= 1.13.
### MISC
- Travis and AppVeyor are gone. We're using GitHub Actions exclusively now.
The whole suite is ran inside Docker (with help of Docker Compose), so it's
easy to run tests locally as well.
Check the new README for some examples!
## v2.6.0 - 2019-10-24
- Add support for TimescaleDB
([#53](https://github.com/go-testfixtures/testfixtures/pull/53)).
## v2.5.3 - 2018-12-15
- Fixes related to use of foreign key pragmas on MySQL (#43).
## v2.5.2 - 2018-11-25
- This library now supports [Go Modules](https://github.com/golang/go/wiki/Modules);
- Also allow `.yaml` (as an alternative to `.yml`) as the file extension (#42).
## v2.5.1 - 2018-11-04
- Allowing disabling reset of PostgreSQL sequences (#38).
## v2.5.0 - 2018-09-07
- Add public function DetectTestDatabase (#35, #36).
## v2.4.5 - 2018-07-07
- Fix for MySQL/MariaDB: ignoring views on operations that should be run only on tables (#33).
## v2.4.4 - 2018-07-02
- Fix for multiple schemas on Microsoft SQL Server (#29 and #30);
- Configuring AppVeyor CI to also test for Microsoft SQL Server.

Sorry, we don't have changelog for older releases 😢.

# testfixtures
[![GoDoc](https://godoc.org/github.com/go-testfixtures/testfixtures?status.svg)][doc]
> ***Warning***: this package will wipe the database data before loading the
fixtures! It is supposed to be used on a test database. Please, double check
if you are running it against the correct database.
> **TIP**: There are options not described in this README page. It's
> recommended that you also check [the documentation][doc].
Writing tests is hard, even more when you have to deal with an SQL database.
This package aims to make writing functional tests for web apps written in
Go easier.
Basically this package mimics the ["Ruby on Rails' way"][railstests] of writing tests
for database applications, where sample data is kept in fixtures files. Before
the execution of every test, the test database is cleaned and the fixture data
is loaded into the database.
The idea is running tests against a real database, instead of relying in mocks,
which is boring to setup and may lead to production bugs not being caught in
the tests.
## Installation
First, import it like this:
```go
import (
"github.com/go-testfixtures/testfixtures/v3"
)
```
## Usage
Create a folder for the fixture files. Each file should contain data for a
single table and have the name `<table_name>.yml`:
```
myapp/
myapp.go
myapp_test.go
...
fixtures/
posts.yml
comments.yml
tags.yml
posts_tags.yml
...
```
The file would look like this (it can have as many record you want):
```yml
# comments.yml
- id: 1
post_id: 1
content: A comment...
author_name: John Doe
author_email: john@doe.com
created_at: 2020-12-31 23:59:59
updated_at: 2020-12-31 23:59:59
- id: 2
post_id: 2
content: Another comment...
author_name: John Doe
author_email: john@doe.com
created_at: 2020-12-31 23:59:59
updated_at: 2020-12-31 23:59:59
# ...
```
An YAML object or array will be converted to JSON. It will be stored on a native
JSON type like JSONB on PostgreSQL or as a TEXT or VARCHAR column on other
databases.
```yml
- id: 1
post_attributes:
author: John Due
author_email: john@due.com
title: "..."
tags:
- programming
- go
- testing
post: "..."
```
If you need to write raw SQL, probably to call a function, prefix the value
of the column with `RAW=`:
```yml
- id: 1
uuid_column: RAW=uuid_generate_v4()
postgis_type_column: RAW=ST_GeomFromText('params...')
created_at: RAW=NOW()
updated_at: RAW=NOW()
```
Your tests would look like this:
```go
package myapp
import (
"database/sql"
_ "github.com/lib/pq"
"github.com/go-testfixtures/testfixtures/v3"
)
var (
db *sql.DB
fixtures *testfixtures.Loader
)
func TestMain(m *testing.M) {
var err error
// Open connection to the test database.
// Do NOT import fixtures in a production database!
// Existing data would be deleted.
db, err = sql.Open("postgres", "dbname=myapp_test")
if err != nil {
...
}
fixtures, err := testfixtures.New(
testfixtures.Database(db), // You database connection
testfixtures.Dialect("postgres"), // Available: "postgresql", "timescaledb", "mysql", "mariadb", "sqlite" and "sqlserver"
testfixtures.Directory("testdata/fixtures"), // the directory containing the YAML files
)
if err != nil {
...
}
os.Exit(m.Run())
}
func prepareTestDatabase() {
if err := fixtures.Load(); err != nil {
...
}
}
func TestX(t *testing.T) {
prepareTestDatabase()
// Your test here ...
}
func TestY(t *testing.T) {
prepareTestDatabase()
// Your test here ...
}
func TestZ(t *testing.T) {
prepareTestDatabase()
// Your test here ...
}
```
Alternatively, you can use the `Files` option, to specify which
files you want to load into the database:
```go
fixtures, err := testfixtures.New(
testfixtures.Database(db),
testfixtures.Dialect("postgres"),
testfixtures.Files(
"fixtures/orders.yml",
"fixtures/customers.yml",
),
)
if err != nil {
...
}
fixtures, err := testfixtures.NewFiles(db, &testfixtures.PostgreSQL{},
"fixtures/orders.yml",
"fixtures/customers.yml",
// add as many files you want
)
if err != nil {
...
}
```
## Security check
In order to prevent you from accidentally wiping the wrong database, this
package will refuse to load fixtures if the database name (or database
filename for SQLite) doesn't contains "test". If you want to disable this
check, use:
```go
testfixtures.New(
...
testfixtures.DangerousSkipTestDatabaseCheck(),
)
```
## Sequences
For PostgreSQL, this package also resets all sequences to a high
number to prevent duplicated primary keys while running the tests.
The default is 10000, but you can change that with:
```go
testfixtures.New(
...
testfixtures.ResetSequencesTo(10000),
)
```
Or, if you want to skip the reset of sequences entirely:
```go
testfixtures.New(
...
testfixtures.SkipResetSequences(),
)
```
## Compatible databases
### PostgreSQL / TimescaleDB
This package has two approaches to disable foreign keys while importing fixtures
for PostgreSQL databases:
#### With `DISABLE TRIGGER`
This is the default approach. For that use:
```go
testfixtures.New(
...
testfixtures.Dialect("postgres"), // or "timescaledb"
)
```
With the above snippet this package will use `DISABLE TRIGGER` to temporarily
disabling foreign key constraints while loading fixtures. This work with any
version of PostgreSQL, but it is **required** to be connected in the database
as a SUPERUSER. You can make a PostgreSQL user a SUPERUSER with:
```sql
ALTER USER your_user SUPERUSER;
```
#### With `ALTER CONSTRAINT`
This approach don't require to be connected as a SUPERUSER, but only work with
PostgreSQL versions >= 9.4. Try this if you are getting foreign key violation
errors with the previous approach. It is as simple as using:
```go
testfixtures.New(
...
testfixtures.Dialect("postgres"),
testfixtures.UseAlterConstraint(),
)
```
Tested using the [github.com/lib/pq](https://github.com/lib/pq) driver.
### MySQL / MariaDB
Just make sure the connection string have
[the multistatement parameter](https://github.com/go-sql-driver/mysql#multistatements)
set to true, and use:
```go
testfixtures.New(
...
testfixtures.Dialect("mysql"), // or "mariadb"
)
```
Tested using the [github.com/go-sql-driver/mysql](https://github.com/go-sql-driver/mysql) driver.
### SQLite
SQLite is also supported. It is recommended to create foreign keys as
`DEFERRABLE` (the default) to prevent problems. See more
[on the SQLite documentation](https://www.sqlite.org/foreignkeys.html#fk_deferred).
(Foreign key constraints are no-op by default on SQLite, but enabling it is
recommended).
```go
testfixtures.New(
...
testfixtures.Dialect("sqlite"),
)
```
Tested using the [github.com/mattn/go-sqlite3](https://github.com/mattn/go-sqlite3) driver.
### Microsoft SQL Server
SQL Server support requires SQL Server >= 2008. Inserting on `IDENTITY` columns
are handled as well. Just make sure you are logged in with a user with
`ALTER TABLE` permission.
```go
testfixtures.New(
...
testfixtures.Dialect("sqlserver"),
)
```
Tested using the `mssql` and `sqlserver` drivers from the
[github.com/denisenkom/go-mssqldb](https://github.com/denisenkom/go-mssqldb) lib.
## Templating
Testfixtures supports templating, but it's disabled by default. Most people
won't need it, but it may be useful to dynamically generate data.
Enable it by doing:
```go
testfixtures.New(
...
testfixtures.Template(),
// the above options are optional
TemplateFuncs(...),
TemplateDelims("{{", "}}"),
TemplateOptions("missingkey=zero"),
TemplateData(...),
)
```
The YAML file could look like this:
```yaml
# It's possible generate values...
- id: {{sha256 "my-awesome-post}}
title: My Awesome Post
text: {{randomText}}
# ... or records
{{range $post := $.Posts}}
- id: {{$post.Id}}
title: {{$post.Title}}
text: {{$post.Text}}
{{end}}
```
## Generating fixtures for a existing database
The following code will generate a YAML file for each table of the database
into a given folder. It may be useful to boostrap a test scenario from a sample
database of your app.
```go
dumper, err := testfixtures.NewDumper(
testfixtures.DumpDatabase(db),
testfixtures.DumpDialect("postgres"), // or your database of choice
testfixtures.DumpDirectory("tmp/fixtures"),
textfixtures.DumpTables( // optional, will dump all table if not given
"posts",
"comments",
"tags",
)
)
if err != nil {
...
}
if err := dumper.Dump(); err != nil {
...
}
```
> This was intended to run in small sample databases. It will likely break
if run in a production/big database.
## Gotchas
### Parallel testing
This library doesn't yet support running tests in parallel! Running tests
in parallel can result in random data being present in the database, which
will likely cause tests to randomly/intermittently fail.
This is specially tricky since it's not immediately clear that `go test ./...`
run tests for each package in parallel. If more than one package use this
library, you can face this issue. Please, use `go test -p 1 ./...` or run tests
for each package in separated commands to fix this issue.
If you're looking into being able to run tests in parallel you can try using
testfixtures together with the [txdb][gotxdb] package, which allows wrapping
each test run in a transaction.
## CLI
We also have a CLI to load fixtures in a given database.
Grab it from the [releases page](https://github.com/go-testfixtures/testfixtures/releases)
and use it like:
```bash
testfixtures -d postgres -c "postgres://user:password@localhost/database" -D testdata/fixtures
```
The connection string changes for each database driver.
Use `--help` for all flags.
## Contributing
We recommend you to [install Task](https://taskfile.dev/#/installation) and
Docker before contributing to this package, since some stuff is automated
using these tools.
It's recommended to use Docker Compose to run tests, since it runs tests for
all supported databases once. To do that you just need to run:
```bash
task docker
```
But if you want to run tests locally, copy the `.sample.env` file as `.env`
and edit it according to your database setup. You'll need to create a database
(likely names `testfixtures_test`) before continuing. Then run the command
for the database you want to run tests against:
```bash
task test:pg # PostgreSQL
task test:mysql # MySQL
task test:sqlite # SQLite
task test:sqlserver # Microsoft SQL Server
```
GitHub Actions (CI) runs the same Docker setup available locally.
## Alternatives
If you don't think using fixtures is a good idea, you can try one of these
packages instead:
- [factory-go][factorygo]: Factory for Go. Inspired by Python's Factory Boy
and Ruby's Factory Girl
- [go-txdb (Single transaction SQL driver for Go)][gotxdb]: Use a single
database transaction for each functional test, so you can rollback to
previous state between tests to have the same database state in all tests
- [go-sqlmock][gosqlmock]: A mock for the sql.DB interface. This allow you to
unit test database code without having to connect to a real database
- [dbcleaner][dbcleaner] - Clean database for testing, inspired by
database_cleaner for Ruby

## Contributing to pq
`pq` has a backlog of pull requests, but contributions are still very
much welcome. You can help with patch review, submitting bug reports,
or adding new functionality. There is no formal style guide, but
please conform to the style of existing code and general Go formatting
conventions when submitting patches.
### Patch review
Help review existing open pull requests by commenting on the code or
proposed functionality.
### Bug reports
We appreciate any bug reports, but especially ones with self-contained
(doesn't depend on code outside of pq), minimal (can't be simplified
further) test cases. It's especially helpful if you can submit a pull
request with just the failing test case (you'll probably want to
pattern it after the tests in
[conn_test.go](https://github.com/lib/pq/blob/master/conn_test.go).
### New functionality
There are a number of pending patches for new functionality, so
additional feature patches will take a while to merge. Still, patches
are generally reviewed based on usefulness and complexity in addition
to time-in-queue, so if you have a knockout idea, take a shot. Feel
free to open an issue discussion your proposed patch beforehand.

# pq - A pure Go postgres driver for Go's database/sql package
[![GoDoc](https://godoc.org/github.com/lib/pq?status.svg)](https://godoc.org/github.com/lib/pq)
[![Build Status](https://travis-ci.org/lib/pq.svg?branch=master)](https://travis-ci.org/lib/pq)
## Install
go get github.com/lib/pq
## Docs
For detailed documentation and basic usage examples, please see the package
documentation at <https://godoc.org/github.com/lib/pq>.
## Tests
`go test` is used for testing. See [TESTS.md](TESTS.md) for more details.
## Features
* SSL
* Handles bad connections for `database/sql`
* Scan `time.Time` correctly (i.e. `timestamp[tz]`, `time[tz]`, `date`)
* Scan binary blobs correctly (i.e. `bytea`)
* Package for `hstore` support
* COPY FROM support
* pq.ParseURL for converting urls to connection strings for sql.Open.
* Many libpq compatible environment variables
* Unix socket support
* Notifications: `LISTEN`/`NOTIFY`
* pgpass support
## Future / Things you can help with
* Better COPY FROM / COPY TO (see discussion in #181)
## Thank you (alphabetical)
Some of these contributors are from the original library `bmizerany/pq.go` whose
code still exists in here.

# Tests
## Running Tests
`go test` is used for testing. A running PostgreSQL
server is required, with the ability to log in. The
database to connect to test with is "pqgotest," on
"localhost" but these can be overridden using [environment
variables](https://www.postgresql.org/docs/9.3/static/libpq-envars.html).
Example:
PGHOST=/run/postgresql go test
## Benchmarks
A benchmark suite can be run as part of the tests:
go test -bench .
## Example setup (Docker)
Run a postgres container:
```
docker run --expose 5432:5432 postgres
```
Run tests:
```
PGHOST=localhost PGPORT=5432 PGUSER=postgres PGSSLMODE=disable PGDATABASE=postgres go test
```

/*
Package pq is a pure Go Postgres driver for the database/sql package.
In most cases clients will use the database/sql package instead of
using this package directly. For example:
import (
"database/sql"
_ "github.com/lib/pq"
)
func main() {
connStr := "user=pqgotest dbname=pqgotest sslmode=verify-full"
db, err := sql.Open("postgres", connStr)
if err != nil {
log.Fatal(err)
}
age := 21
rows, err := db.Query("SELECT name FROM users WHERE age = $1", age)
…
}
You can also connect to a database using a URL. For example:
connStr := "postgres://pqgotest:password@localhost/pqgotest?sslmode=verify-full"
db, err := sql.Open("postgres", connStr)
Connection String Parameters
Similarly to libpq, when establishing a connection using pq you are expected to
supply a connection string containing zero or more parameters.
A subset of the connection parameters supported by libpq are also supported by pq.
Additionally, pq also lets you specify run-time parameters (such as search_path or work_mem)
directly in the connection string. This is different from libpq, which does not allow
run-time parameters in the connection string, instead requiring you to supply
them in the options parameter.
For compatibility with libpq, the following special connection parameters are
supported:
* dbname - The name of the database to connect to
* user - The user to sign in as
* password - The user's password
* host - The host to connect to. Values that start with / are for unix
domain sockets. (default is localhost)
* port - The port to bind to. (default is 5432)
* sslmode - Whether or not to use SSL (default is require, this is not
the default for libpq)
* fallback_application_name - An application_name to fall back to if one isn't provided.
* connect_timeout - Maximum wait for connection, in seconds. Zero or
not specified means wait indefinitely.
* sslcert - Cert file location. The file must contain PEM encoded data.
* sslkey - Key file location. The file must contain PEM encoded data.
* sslrootcert - The location of the root certificate file. The file
must contain PEM encoded data.
Valid values for sslmode are:
* disable - No SSL
* require - Always SSL (skip verification)
* verify-ca - Always SSL (verify that the certificate presented by the
server was signed by a trusted CA)
* verify-full - Always SSL (verify that the certification presented by
the server was signed by a trusted CA and the server host name
matches the one in the certificate)
See http://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING
for more information about connection string parameters.
Use single quotes for values that contain whitespace:
"user=pqgotest password='with spaces'"
A backslash will escape the next character in values:
"user=space\ man password='it\'s valid'"
Note that the connection parameter client_encoding (which sets the
text encoding for the connection) may be set but must be "UTF8",
matching with the same rules as Postgres. It is an error to provide
any other value.
In addition to the parameters listed above, any run-time parameter that can be
set at backend start time can be set in the connection string. For more
information, see
http://www.postgresql.org/docs/current/static/runtime-config.html.
Most environment variables as specified at http://www.postgresql.org/docs/current/static/libpq-envars.html
supported by libpq are also supported by pq. If any of the environment
variables not supported by pq are set, pq will panic during connection
establishment. Environment variables have a lower precedence than explicitly
provided connection parameters.
The pgpass mechanism as described in http://www.postgresql.org/docs/current/static/libpq-pgpass.html
is supported, but on Windows PGPASSFILE must be specified explicitly.
Queries
database/sql does not dictate any specific format for parameter
markers in query strings, and pq uses the Postgres-native ordinal markers,
as shown above. The same marker can be reused for the same parameter:
rows, err := db.Query(`SELECT name FROM users WHERE favorite_fruit = $1
OR age BETWEEN $2 AND $2 + 3`, "orange", 64)
pq does not support the LastInsertId() method of the Result type in database/sql.
To return the identifier of an INSERT (or UPDATE or DELETE), use the Postgres
RETURNING clause with a standard Query or QueryRow call:
var userid int
err := db.QueryRow(`INSERT INTO users(name, favorite_fruit, age)
VALUES('beatrice', 'starfruit', 93) RETURNING id`).Scan(&userid)
For more details on RETURNING, see the Postgres documentation:
http://www.postgresql.org/docs/current/static/sql-insert.html
http://www.postgresql.org/docs/current/static/sql-update.html
http://www.postgresql.org/docs/current/static/sql-delete.html
For additional instructions on querying see the documentation for the database/sql package.
Data Types
Parameters pass through driver.DefaultParameterConverter before they are handled
by this package. When the binary_parameters connection option is enabled,
[]byte values are sent directly to the backend as data in binary format.
This package returns the following types for values from the PostgreSQL backend:
- integer types smallint, integer, and bigint are returned as int64
- floating-point types real and double precision are returned as float64
- character types char, varchar, and text are returned as string
- temporal types date, time, timetz, timestamp, and timestamptz are
returned as time.Time
- the boolean type is returned as bool
- the bytea type is returned as []byte
All other types are returned directly from the backend as []byte values in text format.
Errors
pq may return errors of type *pq.Error which can be interrogated for error details:
if err, ok := err.(*pq.Error); ok {
fmt.Println("pq error:", err.Code.Name())
}
See the pq.Error type for details.
Bulk imports
You can perform bulk imports by preparing a statement returned by pq.CopyIn (or
pq.CopyInSchema) in an explicit transaction (sql.Tx). The returned statement
handle can then be repeatedly "executed" to copy data into the target table.
After all data has been processed you should call Exec() once with no arguments
to flush all buffered data. Any call to Exec() might return an error which
should be handled appropriately, but because of the internal buffering an error
returned by Exec() might not be related to the data passed in the call that
failed.
CopyIn uses COPY FROM internally. It is not possible to COPY outside of an
explicit transaction in pq.
Usage example:
txn, err := db.Begin()
if err != nil {
log.Fatal(err)
}
stmt, err := txn.Prepare(pq.CopyIn("users", "name", "age"))
if err != nil {
log.Fatal(err)
}
for _, user := range users {
_, err = stmt.Exec(user.Name, int64(user.Age))
if err != nil {
log.Fatal(err)
}
}
_, err = stmt.Exec()
if err != nil {
log.Fatal(err)
}
err = stmt.Close()
if err != nil {
log.Fatal(err)
}
err = txn.Commit()
if err != nil {
log.Fatal(err)
}
Notifications
PostgreSQL supports a simple publish/subscribe model over database
connections. See http://www.postgresql.org/docs/current/static/sql-notify.html
for more information about the general mechanism.
To start listening for notifications, you first have to open a new connection
to the database by calling NewListener. This connection can not be used for
anything other than LISTEN / NOTIFY. Calling Listen will open a "notification
channel"; once a notification channel is open, a notification generated on that
channel will effect a send on the Listener.Notify channel. A notification
channel will remain open until Unlisten is called, though connection loss might
result in some notifications being lost. To solve this problem, Listener sends
a nil pointer over the Notify channel any time the connection is re-established
following a connection loss. The application can get information about the
state of the underlying connection by setting an event callback in the call to
NewListener.
A single Listener can safely be used from concurrent goroutines, which means
that there is often no need to create more than one Listener in your
application. However, a Listener is always connected to a single database, so
you will need to create a new Listener instance for every database you want to
receive notifications in.
The channel name in both Listen and Unlisten is case sensitive, and can contain
any characters legal in an identifier (see
http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
for more information). Note that the channel name will be truncated to 63
bytes by the PostgreSQL server.
You can find a complete, working example of Listener usage at
https://godoc.org/github.com/lib/pq/example/listen.

There are helper functions available to get the value stored in a Flag if you have a FlagSet but find
it difficult to keep up with all of the pointers in your code.
If you have a pflag.FlagSet with a flag called 'flagname' of type int you
can use GetInt() to get the int value. But notice that 'flagname' must exist
and it must be an int. GetString("flagname") will fail.

if you are running it against the correct database.
Writing tests is hard, even more when you have to deal with an SQL database.
This package aims to make writing functional tests for web apps written in
Go easier.
Basically this package mimics the ["Rails' way"][railstests] of writing tests
for database applications, where sample data is kept in fixtures files. Before
the execution of every test, the test database is cleaned and the fixture data
is loaded into the database.
The idea is running tests against a real database, instead of relying in mocks,
which is boring to setup and may lead to production bugs not being caught in
the tests.
## Installation
First, get it:
```bash
go get -u -v gopkg.in/testfixtures.v2
```
## Usage
Create a folder for the fixture files. Each file should contain data for a
single table and have the name `<table_name>.yml`:
```
myapp/
myapp.go
myapp_test.go
...
fixtures/
posts.yml
comments.yml
tags.yml
posts_tags.yml
...
```
The file would look like this (it can have as many record you want):
```yml
# comments.yml
- id: 1
post_id: 1
content: A comment...
author_name: John Doe
author_email: john@doe.com
created_at: 2016-01-01 12:30:12
updated_at: 2016-01-01 12:30:12
- id: 2
post_id: 2
content: Another comment...
author_name: John Doe
author_email: john@doe.com
created_at: 2016-01-01 12:30:12
updated_at: 2016-01-01 12:30:12
# ...
```
An YAML object or array will be converted to JSON. It can be stored on a native
JSON type like JSONB on PostgreSQL or as a TEXT or VARCHAR column on other
databases.
```yml
- id: 1
post_attributes:
author: John Due
author_email: john@due.com
title: "..."
tags:
- programming
- go
- testing
post: "..."
```
If you need to write raw SQL, probably to call a function, prefix the value
of the column with `RAW=`:
```yml
- id: 1
uuid_column: RAW=uuid_generate_v4()
postgis_type_column: RAW=ST_GeomFromText('params...')
created_at: RAW=NOW()
updated_at: RAW=NOW()
```
Your tests would look like this:
```go
package myapp
import (
"database/sql"
"log"
_ "github.com/lib/pq"
"gopkg.in/testfixtures.v2"
)
var (
db *sql.DB
fixtures *testfixtures.Context
)
func TestMain(m *testing.M) {
var err error
// Open connection with the test database.
// Do NOT import fixtures in a production database!
// Existing data would be deleted
db, err = sql.Open("postgres", "dbname=myapp_test")
if err != nil {
log.Fatal(err)
}
// creating the context that hold the fixtures
// see about all compatible databases in this page below
   fixtures, err = testfixtures.NewFolder(db, &testfixtures.PostgreSQL{}, "testdata/fixtures")
if err != nil {
log.Fatal(err)
}
os.Exit(m.Run())
}
func prepareTestDatabase() {
if err := fixtures.Load(); err != nil {
log.Fatal(err)
}
}
func TestX(t *testing.T) {
prepareTestDatabase()
// your test here ...
}
func TestY(t *testing.T) {
prepareTestDatabase()
// your test here ...
}
func TestZ(t *testing.T) {
prepareTestDatabase()
// your test here ...
}
```
Alternatively, you can use the `NewFiles` function, to specify which
files you want to load into the database:
```go
fixtures, err := testfixtures.NewFiles(db, &testfixtures.PostgreSQL{},
"fixtures/orders.yml",
"fixtures/customers.yml",
// add as many files you want
)
if err != nil {
log.Fatal(err)
}
```
## Security check
In order to prevent you from accidentally wiping the wrong database, this
package will refuse to load fixtures if the database name (or database
filename for SQLite) doesn't contains "test". If you want to disable this
check, use:
```go
testfixtures.SkipDatabaseNameCheck(true)
```
## Sequences
For PostgreSQL or Oracle, this package also resets all sequences to a high
number to prevent duplicated primary keys while running the tests.
The default is 10000, but you can change that with:
```go
testfixtures.ResetSequencesTo(10000)
```
## Compatible databases
### PostgreSQL
This package has two approaches to disable foreign keys while importing fixtures
in PostgreSQL databases:
#### With `DISABLE TRIGGER`
This is the default approach. For that use:
```go
&testfixtures.PostgreSQL{}
```
With the above snippet this package will use `DISABLE TRIGGER` to temporarily
disabling foreign key constraints while loading fixtures. This work with any
version of PostgreSQL, but it is **required** to be connected in the database
as a SUPERUSER. You can make a PostgreSQL user a SUPERUSER with:
```sql
ALTER USER your_user SUPERUSER;
```
#### With `ALTER CONSTRAINT`
This approach don't require to be connected as a SUPERUSER, but only work with
PostgreSQL versions >= 9.4. Try this if you are getting foreign key violation
errors with the previous approach. It is as simple as using:
```go
&testfixtures.PostgreSQL{UseAlterConstraint: true}
```
#### Skipping reset of sequences
You can skip the reset of PostgreSQL sequences if you're debugging a problem
with it, but most of the time you shouldn't do it:
```go
&testfixtures.PostgreSQL{SkipResetSequences: true}
```
### MySQL / MariaDB
Just make sure the connection string have
[the multistatement parameter](https://github.com/go-sql-driver/mysql#multistatements)
set to true, and use:
```go
&testfixtures.MySQL{}
```
### SQLite
SQLite is also supported. It is recommended to create foreign keys as
`DEFERRABLE` (the default) to prevent problems. See more
[on the SQLite documentation](https://www.sqlite.org/foreignkeys.html#fk_deferred).
(Foreign key constraints are no-op by default on SQLite, but enabling it is
recommended).
```go
&testfixtures.SQLite{}
```
### Microsoft SQL Server
SQL Server support requires SQL Server >= 2008. Inserting on `IDENTITY` columns
are handled as well. Just make sure you are logged in with a user with
`ALTER TABLE` permission.
```go
&testfixtures.SQLServer{}
```
### Oracle
Oracle is supported as well. Use:
```go
&testfixtures.Oracle{}
```
## Generating fixtures for a existing database (experimental)
The following code will generate a YAML file for each table of the database in
the given folder. It may be useful to boostrap a test scenario from a sample
database of your app.
```go
err := testfixtures.GenerateFixtures(db, &testfixtures.PostgreSQL{}, "testdata/fixtures")
if err != nil {
log.Fatalf("Error generating fixtures: %v", err)
}
```
Or
```go
err := testfixtures.GenerateFixturesForTables(
db,
[]*TableInfo{
&TableInfo{Name: "table_name", Where: "foo = 'bar'"},
// ...
},
&testfixtures.PostgreSQL{},
"testdata/fixtures",
)
if err != nil {
log.Fatalf("Error generating fixtures: %v", err)
}
```
> This was thought to run in small sample databases. It will likely break
if run in a production/big database.
## Gotchas
### Parallel testing
This library doesn't yet support running tests in parallel! Running tests
in parallel can result in random data being present in the database, which
will likely cause tests to randomly/intermittently fail.
This is specially tricky since it's not immediately clear that `go test ./...`
run tests for each package in parallel. If more than one package use this
library, you can face this issue. Please, use `go test -p 1 ./...` or run tests
for each package in separated commands to fix this issue.
See [#40](https://github.com/go-testfixtures/testfixtures/issues/40)
and [golang/go#11521](https://github.com/golang/go/issues/11521) for more information.
We're also planning to implement transactional tests to allow running tests
in parallel (see [#24](https://github.com/go-testfixtures/testfixtures/issues/24)).
Running each test package in a separated database would also allow you to do that.
Open issues for other ideas :slightly_smiling_face:.
## Contributing
Tests were written to ensure everything work as expected. You can run the tests
with:
```bash
# running tests for PostgreSQL
go test -tags postgresql
# running test for MySQL
go test -tags mysql
# running tests for SQLite
go test -tags sqlite
# running tests for SQL Server
go test -tags sqlserver
# running tests for Oracle
go test -tags oracle
# running test for multiple databases at once
go test -tags 'sqlite postgresql mysql'
# running tests + benchmark
go test -v -bench=. -tags postgresql
```
Travis runs tests for PostgreSQL, MySQL and SQLite. AppVeyor run for all
these and also Microsoft SQL Server.
To set the connection string of tests for each database, copy the `.sample.env`
file as `.env` and edit it according to your environment.
## Alternatives
If you don't think using fixtures is a good idea, you can try one of these
packages instead:
- [factory-go][factorygo]: Factory for Go. Inspired by Python's Factory Boy
and Ruby's Factory Girl
- [go-txdb (Single transaction SQL driver for Go)][gotxdb]: Use a single
database transaction for each functional test, so you can rollback to
previous state between tests to have the same database state in all tests
- [go-sqlmock][gosqlmock]: A mock for the sql.DB interface. This allow you to
unit test database code without having to connect to a real database
- [dbcleaner][dbcleaner] - Clean database for testing, inspired by
database_cleaner for Ruby
[railstests]: http://guides.rubyonrails.org/testing.html#the-test-database
[gotxdb]: https://github.com/DATA-DOG/go-txdb
[gosqlmock]: https://github.com/DATA-DOG/go-sqlmock
[factorygo]: https://github.com/bluele/factory-go
