CakePHP使用映射方法测试行为 [英] CakePHP test behaviour with mapped method

问题描述

在创建 OwnableBehavior 时，我决定使用可用的 $ mapMethods 属性。它将任何名为 isOwnedByXXX（）的方法映射到 isOwnedBy（）（此文档的链接为< a href = http://book.cakephp.org/2.0/en/models/behaviors.html#mapped-methods rel = nofollow>此处）

Whilst creating an OwnableBehavior I decided to use the $mapMethods property that is available. It is to map any method called isOwnedByXXX() to isOwnedBy() (The link for the documentation on this is here)

这是我的 OwnableBehavior 代码：

class OwnableBehavior extends Model Behavior {

    public $mapMethods = array('/isOwnedBy(\w+)/' => 'isOwnedBy');

    public function isOwnedBy(Model $model, $type, $id, Model $userModel, $userId) {
         // Method is currently empty
    }
}

这是TestCase代码：

Here is the TestCase code:

class OwnableBehaviorTest extends CakeTestCase {

    public function testIsOwned() {
        $TestModel = new Avatar();
        $TestModel->Behaviors->attach('Ownable');
        $result = $TestModel->Behaviors->Ownable->isOwnedByUser(
            $TestModel, 1, new User(), 1);
        $this->assertTrue($result);
    }
}

运行测试时出现此错误：

When I run the test I get this error:

 Call to undefined method OwnableBehavior::isOwnedByUser()

如果我将方法调用更改为 isOwnedBy（$ TestModel，'user'，1，new User（），1）; 这行得通，因此由于某种原因看起来映射的方法在单元测试期间不起作用。我已经在控制器中测试了映射的方法，但是没有任何错误。

If I change the method call to isOwnedBy($TestModel, 'user', 1, new User(), 1); this works, so it looks like for some reason the mapped methods aren't working during the unit test. I have tested the mapped methods in a controller and I get no errors.

我想知道是否取决于将行为加载到模型中的原因。我在食谱中找不到有关如何正确测试行为的文档，例如组件，助手等。因此，我只是使用了核心行为测试所使用的相同技术（位于 Cake / Test / Case / Model / Behavior / ）。

I wondered if it was down to how I was loading the behaviour into the model. I couldn't find any documentation in the cookbook on how to properly test Behaviours like there is with Components, Helpers, etc... So I just used the same techniques that the Core Behaviour tests use (Found in Cake/Test/Case/Model/Behavior/).

我确实认为可能是因为我覆盖了这一事实 ModelBehavior :: setup（）方法，但是我尝试添加 parent :: setup（$ model，$ settings）在安装方法的开始，我仍然遇到相同的错误。我不会覆盖其他任何 ModelBehavior 方法。

I did think maybe it could have been down to the fact that I am overwriting the ModelBehavior::setup() method, but I tried adding parent::setup($model, $settings) at the start of the setup method and I still get the same error. I am not overwriting any of the other ModelBehavior methods.

我想我可以只使用 OwnableBehavior :: isOwnedBy（）方法，但是我很想知道是否可以在单元测试期间使映射的方法正常工作。

I guess I could just use the OwnableBehavior::isOwnedBy() method, but I'd quite like to know if I could get the mapped methods to work during a unit test.

推荐答案

我找到的解决方案正在替换此行：

The solution I have found is replacing this line:

$result = $TestModel->Behaviors->Ownable->isOwnedByUser(...);

具有：

$result = $TestModel->isOwnedByUser(...);

因此，只是像在应用程序中那样使用它，直接调用行为方法从模型。我不知道这是否会破坏单元测试的想法，并将其更多地用于集成测试。

So it's just a case of using it more like you would in the application, calling the behaviour method directly from the model. I don't know if this ruins the idea of a unit test and makes it more into integration testing though.
