php - 软断言和模拟方法测试失败

Question

我正在学习本教程:http://jtreminio.com/2013/03/unit-testing-tutorial-part-5-mock-methods-and-overriding-constructors/ .了解 PHPUnit 工作原理的绝佳教程。

但是我无法理解，因为测试没有通过。

失败是:

Method was expected to be called 1 times, actually called 0 times.

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 方法中运行并通过测试。

        $badCode->expects($this->once())
            ->method('callExit');

它失败是因为是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

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。 不能对模拟方法进行任何断言，只能对 stub 进行断言。

BadCode.php

<?php

namespace phpUnitTutorial;

class BadCode
{
    protected $user;

    public function __construct(array $user)
    {
        $this->user = $user;
    }

    public function authorize($password)
    {
        if ($this->checkPassword($password)) {
            return true;
        }

        return false;
    }

    protected function checkPassword($password)
    {
        if (empty($this->user['password']) || $this->user['password'] !== $password) {
            echo 'YOU SHALL NOT PASS';
            $this->callExit();
        }

        return true;
    }

    protected function callExit()
    {
        exit;
    }
}

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'))

        $badCode->expects($this->once())
            ->method('callExit');

        $this->expectOutputString('YOU SHALL NOT PASS');

        $badCode->authorize($password);
    }
}

Answer 1

作者在这里 - 我捏造了那部分，AppFog(我的主机)在使用免费帐户(我的)时遇到问题，所以我现在无法更新它。

此外，是的，它应该是 checkPassword() 中的 $this->user
