Class yii\test\InitDbFixture

Inheritanceyii\test\InitDbFixture » yii\test\DbFixture » yii\test\Fixture » yii\base\Component » yii\base\BaseObject
Implementsyii\base\Configurable
Available since version2.0
Source Code https://github.com/yiisoft/yii2/blob/master/framework/test/InitDbFixture.php

InitDbFixture represents the initial state needed for DB-related tests.

Its main task is to toggle integrity check of the database during data loading. This is needed by other DB-related fixtures (e.g. yii\test\ActiveFixture) so that they can populate data into the database without triggering integrity check errors.

Besides, DbFixture also attempts to load an initialization script if it exists.

You should normally use InitDbFixture to prepare a skeleton test database. Other DB fixtures will then add specific tables and data to this database.

For more details and usage information on InitDbFixture, see the guide article on fixtures.

Property Details

Hide inherited properties

$initScript public property

The init script file that should be executed when loading this fixture. This should be either a file path or path alias. Note that if the file does not exist, no error will be raised.

public string $initScript = '@app/tests/fixtures/initdb.php'
$schemas public property

List of database schemas that the test tables may reside in. Defaults to [''], meaning using the default schema (an empty string refers to the default schema). This property is mainly used when turning on and off integrity checks so that fixture data can be populated into the database without causing problem.

public array $schemas = [
'',
]

Method Details

Hide inherited methods

__call() public method

Defined in: yii\base\Component::__call()

Calls the named method which is not a class method.

This method will check if any attached behavior has the named method and will execute it if available.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

public mixed __call ( $name, $params )
$name string

The method name
$params array

Method parameters
return mixed

The method return value
throws yii\base\UnknownMethodException

when calling unknown method

 

 public function __call($name, $params)
{
 $this->ensureBehaviors();
 foreach ($this->_behaviors as $object) {
 if ($object->hasMethod($name)) {
 return call_user_func_array([$object, $name], $params);
 }
 }
 throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
__clone() public method

Defined in: yii\base\Component::__clone()

This method is called after the object is created by cloning an existing one.

It removes all behaviors because they are attached to the old object.

public void __clone ( )

 public function __clone()
{
 $this->_events = [];
 $this->_eventWildcards = [];
 $this->_behaviors = null;
}
__construct() public method

Defined in: yii\base\BaseObject::__construct()

Constructor.

The default implementation does two things:

  • Initializes the object with the given configuration $config.
  • Call init().

If this method is overridden in a child class, it is recommended that

  • the last parameter of the constructor is a configuration array, like $config here.
  • call the parent implementation at the end of the constructor.
public void __construct ( $config = [] )
$config array

Name-value pairs that will be used to initialize the object properties

 public function __construct($config = [])
{
 if (!empty($config)) {
 Yii::configure($this, $config);
 }
 $this->init();
}
__get() public method

Defined in: yii\base\Component::__get()

Returns the value of a component property.

This method will check in the following order and act accordingly:

  • a property defined by a getter: return the getter result
  • a property of a behavior: return the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $component->property;.

See also __set().

public mixed __get ( $name )
$name string

The property name
return mixed

The property value or the value of a behavior's property
throws yii\base\UnknownPropertyException

if the property is not defined
throws yii\base\InvalidCallException

{
 $getter = 'get' . $name;
 if (method_exists($this, $getter)) {
 // read property, e.g. getName()
 return $this->$getter();
 }
 // behavior property
 $this->ensureBehaviors();
 foreach ($this->_behaviors as $behavior) {
 if ($behavior->canGetProperty($name)) {
 return $behavior->$name;
 }
 }
 if (method_exists($this, 'set' . $name)) {
 throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
 }
 throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
}
__isset() public method

Defined in: yii\base\Component::__isset()

Checks if a property is set, i.e. defined and not null.

This method will check in the following order and act accordingly:

  • a property defined by a setter: return whether the property is set
  • a property of a behavior: return whether the property is set
  • return false for non existing properties

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($component->property).

See also https://www.php.net/manual/en/function.isset.php.

public boolean __isset ( $name )
$name string

The property name or the event name
return boolean

Whether the named property is set

 

 public function __isset($name)
{
 $getter = 'get' . $name;
 if (method_exists($this, $getter)) {
 return $this->$getter() !== null;
 }
 // behavior property

 return $behavior->$name !== null;
 }
 }
 return false;
}
__set() public method

Defined in: yii\base\Component::__set()

Sets the value of a component property.

This method will check in the following order and act accordingly:

  • a property defined by a setter: set the property value
  • an event in the format of "on xyz": attach the handler to the event "xyz"
  • a behavior in the format of "as xyz": attach the behavior named as "xyz"
  • a property of a behavior: set the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $component->property = $value;.

See also __get().

behaviors() public method

Defined in: yii\base\Component::behaviors()

Returns a list of behaviors that this component should behave as.

Child classes may override this method to specify the behaviors they want to behave as.

The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:

'behaviorName' => [
 'class' => 'BehaviorClass',
 'property1' => 'value1',
 'property2' => 'value2',
]

Note that a behavior class must extend from yii\base\Behavior. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using getBehavior() or be detached using detachBehavior(). Anonymous behaviors can not be retrieved or detached.

Behaviors declared in this method will be attached to the component automatically (on demand).
