Swtiching a over to cakephp 2.1 and just starting to learn unit testing...

When I ArticlesControllerTestCase::testView()

and run 

$this->testAction('articles/view/1'); 
debug($this->view); 
debug($this->contents); 
die;

both $this->view and $this->contents is equal to null

I've emptied the beforeFilter calls and beforeRender calls to try and elimitate that...

I noticed that in the controller action, if I set $this->render('view'); at the end of the method I get $this->view = 'what it is suppose to be', but $this->contents = 'to the same thing and does not contain the layout

any idea why this would be happening?

如果您被重定向，例如，如果会话数据不符合预期，某些身份验证代码会重定向到登录页面，则可能会发生这种情况。如果您没有在测试中设置所需的环境，您将被重定向。您可以通过检查以下值来检查$this->headers：

debug("Headers: " . print_r($this->headers));

如果您将其放入测试中并看到类似的array('Location' => 'your_login_page')内容，请确保您的测试环境包含使您的身份验证系统（或任何其他可能插入重定向）满意所需的一切。

您需要捕获 $this->testAction 的结果并指定要返回的内容（http://book.cakephp.org/2.0/en/development/testing.html#testing-controllers）

例如

$result = $this->testAction('articles/view/1', array('return'=>'content'));

debug($result);

如果您计划执行单元测试，您应该真正考虑测试每个单独的单元。话虽这么说，PHPUnit 在集成到 CakePHP 时相当健壮，可以提供您需要的东西，例如数据和方法模拟。

当我编写单元测试时，它看起来有点像这样：

function testSomeTestCaseWithDescriptiveMethodName(){
    $this->testAction("controller/action/arguments");
    $this->assertEqual([some value or data set], $this->vars["key"];
}

这将允许您在不进行集成测试（包括视图、数据库访问等）的情况下针对创建的值进行测试。

我希望这有帮助。:)

我想我知道导致问题的原因。您需要为 testAction() 提供方法。

$this->testAction('articles/view/1', array('method'=>'get')); 
debug($this->view); //should output the view
debug($this->contents);  //should output the contents

恕我直言，文档（http://book.cakephp.org/2.0/en/development/testing.html#testing-controllers）看起来默认是 GET。默认值实际上是 POST - 因此“发布”到文章/视图/1 将一无所获。
