如何测试 Laravel 5 控制器方法

Question

我们有 Laravel 5 控制器方法：

public function getInput()
{
    $input = \Request::all();
    $links = $input['links'];
    $this->startLinks =  explode("\n", $links);
    return $this;
}

我们如何测试这个单一的方法？如何将带有数据的 POST 请求传递给此方法？以及如何在我的测试方法中创建此控制器的实例 class？

Answer 1

这看起来像是一种可能不应该属于控制器的方法。如果您认真对待测试，我强烈建议您阅读存储库模式。测试时，将所有内容从控制器中抽象出来会让您的生活变得更加轻松。=

尽管如此，这仍然是非常可测试的。主要思想是找出需要测试的内容并只测试它。这意味着我们不关心依赖项在做什么，只关心它们在做什么并返回方法的其余部分需要的东西。在本例中，它是 Request 门面。

然后您要确保正确设置了变量，并且该方法返回了该 class 的一个实例。它实际上最终非常简单。

应该看起来像这样...

public function testGetInput()
{
    $requestParams = [
        'links' => "somelink.com\nsomeotherlink.com\nandanotherlink.com\ndoesntmatter.com"
    ];

    // Here we are saying the \Request facade should expect the all method to be called and that all method should
    // return some pre-defined things which we will use in our asserts.
    \Request::shouldReceive('all')->once()->andReturn($requestParams);

    // Here we are just using Laravel's IoC container to instantiate your controller.  Change YourController to whatever
    // your controller is named
    $class = App::make('YourController');

    // Getting results of function so we can test that it has some properties which were supposed to have been set.
    $return = $class->getInput();

    // Again change this to the actual name of your controller.
    $this->assertInstanceOf('YourController', $return);

    // Now test all the things.
    $this->assertTrue(isset($return->startLinks));
    $this->assertTrue(is_array($return->startLinks));
    $this->assertTrue(in_array('somelink.com', $return->startLInks));
    $this->assertTrue(in_array('nsomeotherlink.com', $return->startLInks));
    $this->assertTrue(in_array('nandanotherlink.com', $return->startLInks));
    $this->assertTrue(in_array('ndoesntmatter.com', $return->startLInks));
}

我想你正在寻找 this。

如果您的测试 class 扩展 TestCase，您将获得很多辅助方法，它们将为您完成繁重的工作。

function testSomething() {
    // POST request to your controller@action
    $response = $this->action('POST', 'YourController@yourAction', ['links' => 'link1 \n link2']);
    // you can check if response was ok
    $this->assertTrue($response->isOk(), "Custom message if something went wrong");
    // or if view received variable
    $this->assertViewHas('links', ['link1', 'link2']);
}

Codeception 进一步扩展了此功能。
