也许我做错了。
我想测试模型的beforeSave方法(抗体)。此方法的一部分调用关联模型(Species)上的方法。我想嘲笑物种模型,但不知道如何。
是否有可能或者我做的事情违背了MVC模式,从而尝试做一些我不应该做的事情?
class Antibody extends AppModel {
public function beforeSave() {
// some processing ...
// retreive species_id based on the input
$this->data['Antibody']['species_id']
= isset($this->data['Species']['name'])
? $this->Species->getIdByName($this->data['Species']['name'])
: null;
return true;
}
}

假设您的Species模型由于关系而由蛋糕创建,您可以简单地执行以下操作:
public function setUp()
{
parent::setUp();
$this->Antibody = ClassRegistry::init('Antibody');
$this->Antibody->Species = $this->getMock('Species');
// now you can set your expectations here
$this->Antibody->Species->expects($this->any())
->method('getIdByName')
->will($this->returnValue(/*your value here*/));
}
public function testBeforeFilter()
{
// or here
$this->Antibody->Species->expects($this->once())
->method('getIdByName')
->will($this->returnValue(/*your value here*/));
}

嗯,这取决于'Species'对象的注入方式。 它是通过构造函数注入的吗?通过二传手?它是继承的吗?
以下是构造函数注入对象的示例:
class Foo
{
/** @var Bar */
protected $bar;
public function __construct($bar)
{
$this->bar = $bar;
}
public function foo() {
if ($this->bar->isOk()) {
return true;
} else {
return false;
}
}
}
然后你的测试会是这样的:
public function test_foo()
{
$barStub = $this->getMock('Overblog\CommonBundle\TestUtils\Bar');
$barStub->expects($this->once())
->method('isOk')
->will($this->returnValue(false));
$foo = new Foo($barStub);
$this->assertFalse($foo->foo());
}
使用setter注入的对象的过程非常相似:
public function test_foo()
{
$barStub = $this->getMock('Overblog\CommonBundle\TestUtils\Bar');
$barStub->expects($this->once())
->method('isOk')
->will($this->returnValue(false));
$foo = new Foo();
$foo->setBar($barStub);
$this->assertFalse($foo->foo());
}
