A key concept in the Yii fixture framework is the so-called *fixture objects*. A fixture object is an instance
of [[yii\test\Fixture]] or its child class. It represents a particular aspect of a test environment. For example,
you may define `UserFixture` to initialize the user database table with a set of known data. You load one or multiple

The former is best suited for general purpose fixtures, while the latter has enhanced features specifically

If you extend from [[yii\test\Fixture]], make sure you override the [[yii\test\Fixture::load()]] method
If you extend from [[yii\test\Fixture]], you should normally override the [[yii\test\Fixture::load()]] method
with your custom code of setting up the test environment (e.g. creating specific directories or files).
In the following, we will mainly describe how to define a database fixture by extending [[yii\test\ActiveFixture]].
Each `ActiveFixture` is about setting up the test data needed by a database table. You may specify the table
Each `ActiveFixture` is about preparing a DB table for testing purpose. You may specify the table

Next, you should provide the data needed by the user table in a file. By default, the file should be located at
`FixturePath/data/TableName.php`, where `FixturePath` stands for the directory containing the fixture class file,
and `TableName` is the name of the table associated with the fixture. In the example above, the file should be
`@app/tests/fixtures/data/tbl_user.php`, assuming the table associated with `User` is `tbl_user`.
Next, you should override [[yii\test\ActiveFixture::loadSchema()]] to create the table. You may wonder why we need
to create the table when loading a fixture and why we do not work with a database which already has the table. This
is because preparing a complete test database is often very time consuming and in most test cases, only a very tiny part
of the database is touched. So the idea here is to create the table only when it is needed by the test.
```php
<?php
namespace app\tests\fixtures;
The data file should return an array of data rows to be inserted into the user table. For example,
use yii\test\ActiveFixture;
class UserFixture extends ActiveFixture
{
public $modelClass = 'app\models\User';
protected function loadSchema()
{
$this->createTable('tbl_user', [
'username' => 'string not null',
'email' => 'string not null',
...
]);
}
}
```
Lastly, you should provide the fixture data in a file located at `FixturePath/data/TableName.php`,
where `FixturePath` stands for the directory containing the fixture class file, and `TableName`
is the name of the table associated with the fixture. In the example above, the file should be
`@app/tests/fixtures/data/tbl_user.php`. The data file should return an array of data rows
to be inserted into the user table. For example,
```php
<?php
return [
'user1' => [
'name' => 'Chase',
'login' => 'lmayert',
'username' => 'lmayert',
'email' => 'strosin.vernice@jerde.com',

Defining and Using Global Fixtures
----------------------------------
The fixtures described above are mainly used by individual test cases. In most cases, you also need some global
fixtures that are applied to ALL or many test cases. An example is [[yii\test\InitDbFixture]] which is used to
set up a skeleton test database and toggle database integrity checks when applying other DB fixtures.
This fixture will try to execute a script located at `@app/tests/fixtures/initdb.php`. In this script, you may,
for example, load a basic DB dump containing the minimal set of tables, etc.
Using global fixtures is similar to using non-global ones. The only difference is that you declare these fixtures
in [[yii\codeception\TestCase::globalFixtures()]] instead of `fixtures()`. When a test case load fixtures, it will
first load global fixtures and then non-global ones.
By default, [[yii\codeception\DbTestCase]] already declares `InitDbFixture` in its `globalFixtures()` method.
