CDbTestCase is the base class for test cases about DB-related features.

CDbTestCase provides database fixture management with the help of CDbFixtureManager. By declaring fixtures property, one can ensure the specified tables have the expected fixture state when executing each test method. In addition, CDbTestCase provides two ways to access the fixture data.

For example, assume we declare fixtures to be:

public $fixtures=array(
    'posts' => 'Post',
    'comments' => 'Comment',
);

We can access the original fixture data rows using $this->posts $this->posts['first post']. We can also retrieve an ActiveRecord instance corresponding to a fixture data row using $this->posts('first post'). Note, here 'first post' refers to a key to a row in the original fixture data.

Property Details

fixtures property

protected array $fixtures;

a list of fixtures that should be loaded before each test method executes. The array keys are fixture names, and the array values are either AR class names or table names. If table names, they must begin with a colon character (e.g. 'Post' means an AR class, while ':post' means a table name). Defaults to false, meaning fixtures will not be used at all.

Method Details

__call() method

public mixed __call(string $name, string $params)
$name	string	method name
$params	string	method parameters
{return}	mixed	the property value

Source Code: framework/test/CDbTestCase.php#73 (show)


public function __call($name,$params)
{
    if(is_array($this->fixtures) && isset($params[0]) && ($record=$this->getFixtureManager()->getRecord($name,$params[0]))!==false)
        return $record;
    else
        throw new Exception("Unknown method '$name' for class '".get_class($this)."'.");
}

PHP magic method. This method is overridden so that named fixture ActiveRecord instances can be accessed in terms of a method call.

__get() method

public mixed __get(string $name)
$name	string	the property name
{return}	mixed	the property value

Source Code: framework/test/CDbTestCase.php#57 (show)


public function __get($name)
{
    if(is_array($this->fixtures) && ($rows=$this->getFixtureManager()->getRows($name))!==false)
        return $rows;
    else
        throw new Exception("Unknown property '$name' for class '".get_class($this)."'.");
}

PHP magic method. This method is overridden so that named fixture data can be accessed like a normal property.

getFixtureData() method

public array getFixtureData(string $name)
$name	string	the fixture name (the key value in fixtures).
{return}	array	the named fixture data

Source Code: framework/test/CDbTestCase.php#93 (show)


public function getFixtureData($name)
{
    return $this->getFixtureManager()->getRows($name);
}

getFixtureManager() method

public CDbFixtureManager getFixtureManager()
{return}	CDbFixtureManager	the database fixture manager

Source Code: framework/test/CDbTestCase.php#84 (show)


public function getFixtureManager()
{
    return Yii::app()->getComponent('fixture');
}

getFixtureRecord() method

public CActiveRecord getFixtureRecord(string $name, string $alias)
$name	string	the fixture name (the key value in fixtures).
$alias	string	the alias of the fixture data row
{return}	CActiveRecord	the ActiveRecord instance corresponding to the specified alias in the named fixture. False is returned if there is no such fixture or the record cannot be found.

Source Code: framework/test/CDbTestCase.php#104 (show)


public function getFixtureRecord($name,$alias)
{
    return $this->getFixtureManager()->getRecord($name,$alias);
}

setUp() method

protected void setUp()

Source Code: framework/test/CDbTestCase.php#114 (show)


protected function setUp()
{
    parent::setUp();
    if(is_array($this->fixtures))
        $this->getFixtureManager()->load($this->fixtures);
}

Sets up the fixture before executing a test method. If you override this method, make sure the parent implementation is invoked. Otherwise, the database fixtures will not be managed properly.
