Codeception Extension for Yii 2
===============================
This extension provides [Codeception](http://codeception.com/) integration for the Yii Framework 2.0.
It provides classes that help with testing with codeception:
- a base class for unit-tests: `yii\codeception\TestCase
- a base class for codeception page-objects: `yii\codeception\BasePage`.
- a solution for testing emails
Installation
------------
The preferred way to install this extension is through [composer](http://getcomposer.org/download/).
Either run
```
php composer.phar require yiisoft/yii2-codeception "*"
```
or add
```json
"yiisoft/yii2-codeception": "*"
```
to the require section of your composer.json.
Usage
-----
When using codeception page-objects they have some similar code, this code was extracted and put into the `BasePage`
class to reduce code duplication. Simply extend your page object from this class, like it is done in `yii2-app-basic` and
`yii2-app-advanced` boilerplates.
For unit testing there is a `TestCase` class which holds some common features like application creation before each test
and application destroy after each test. You can configure a mock application using this class.
`TestCase` is extended from `PHPUnit_Framework_TestCase` so all methods and assertions are available.
```php
<?php
SomeConsoleTest extends \yii\codeception\TestCase
{
// this is the config file to load as application config
public static $applicationConfig = '@app/config/web.php';
// this defines the application class to use for mock applications
protected $applicationClass = 'yii\web\Application';
}
```
The `$applicationConfig` property may be set for all tests in a `_bootstrap.php` file like this:
```php
<?php
yii\codeception\TestCase::$applicationConfig = yii\helpers\ArrayHelper::merge(
require(__DIR__ . '/../../config/web.php'),
require(__DIR__ . '/../../config/codeception/unit.php')
);
```
Don't forget that you have to include autoload and Yii class in the `_bootstrap.php` file.
You also can reconfigure some components for tests, for this purpose there is a `$config` property in the `TestCase` class.
```php
<?php
SomeOtherTest extends \yii\codeception\TestCase
{
public $config = [
'components' => [
'mail' => [
'useFileTransport' => true,
],
]
];
}
```
Because of Codeception buffers all output you can't make simple `var_dump()` in the TestCase, instead you need to use
`Codeception\Util\Debug::debug()` function and then run test with `--debug` key, for example:
```php
<?php
use Codeception\Util\Debug;
SomeDebugTest extends \yii\codeception\TestCase
{
public function testSmth()
{
Debug::debug('some string');
Debug::debug($someArray);
Debug::debug($someObject);
}
}
```
Then run command `php codecept.phar run --debug unit/SomeDebugTest` and you will see in output:
```html
some string
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
)
yii\web\User Object
(
[identityClass] => app\models\User
[enableAutoLogin] =>
[loginUrl] => Array
(
[0] => site/login
)
[identityCookie] => Array
(
[name] => _identity
[httpOnly] => 1
)
[authTimeout] =>
[autoRenewCookie] => 1
[idVar] => __id
[authTimeoutVar] => __expire
[returnUrlVar] => __returnUrl
[_access:yii\web\User:private] => Array
(
)
[_identity:yii\web\User:private] =>
[_events:yii\base\Component:private] =>
[_behaviors:yii\base\Component:private] =>
)
```
