如何表明PHPUnit测试预计会失败？

Question

是否可以使用PHPUnit将测试标记为"预期失败"？这在执行TDD时很有用,并且您希望区分真正失败的测试和由于尚未编写相关代码而导致失败的测试.

Answer 1

我认为在这些情况下,简单地将测试标记为跳过是相当标准的.您的测试仍将运行且套件将通过,但测试运行器将提醒您跳过的测试.

Answer 2

处理此问题的"正确"方法是使用$this->markTestIncomplete().这将标记测试不完整.它会在返回时返回,但会显示提供的消息.有关更多信息,请参见http://www.phpunit.de/manual/3.0/en/incomplete-and-skipped-tests.html.

Answer 3

我认为这是一个不好的做法,但你可以用这种方式欺骗PHPUnit:

/**
 * This test will succeed !!!
 * @expectedException PHPUnit_Framework_ExpectationFailedException
 */
public function testSucceed()
{
    $this->assertTrue(false);
}

更干净:

  public function testFailingTest() {  
    try {  
      $this->assertTrue(false);  
    } catch (PHPUnit_Framework_ExpectationFailedException $ex) {  
      // As expected the assertion failed, silently return  
      return;  
    }  
    // The assertion did not fail, make the test fail  
    $this->fail('This test did not fail as expected');  
  }
