我正在关注本教程：http: //jtreminio.com/2013/03/unit-testing-tutorial-part-5-mock-methods-and-overriding-constructors/。一个很棒的教程，用于了解 PHPUnit 的工作原理。
但我无法理解，因为测试没有通过。
失败是：
Method was expected to be called 1 times, actually called 0 times.
在这部分代码：
$badCode->expects($this->once())
->method('checkPassword')
->with($password);
但这是不可能的，因为下一个软断言在 checkPassword 方法中运行并通过了测试。
$badCode->expects($this->once())
->method('callExit');
它失败是因为是一个模拟方法并且行为不同？还是代码错了？
为了便于理解，我附上了所有文件，这是一个小例子。

BadCodeTest.php
<?php
namespace phpUnitTutorial\Test;
class BadCodeTest extends \PHPUnit_Framework_TestCase
{
public function testAuthorizeExitsWhenPasswordNotSet()
{
$user = array('username' => 'jtreminio');
$password = 'foo';
$badCode = $this->getMockBuilder('phpUnitTutorial\BadCode')
->setConstructorArgs(array($user))
->setMethods(array('callExit'))
->getMock();
$badCode->expects($this->once())
->method('checkPassword')
->with($password);
$badCode->expects($this->once())
->method('callExit');
$this->expectOutputString('YOU SHALL NOT PASS');
$badCode->authorize($password);
}
}
有人可以帮助我吗？谢谢！
更新
博客的作者用解决方案更新了教程。不能对模拟方法做任何断言，只能做存根。
