Phpunit，期望一个方法正好运行两次

Question

class TestMe
{
    public function method() { }
}

测试:

class TestTest extends PHPUnit_Framework_TestCase
{
    public function testA()
    {
        $stub = $this->getMock ('TestMe');
        $stub->expects ($this->exactly(2))->method('method');
    }

    public function testB()
    {
        $stub = $this->getMock ('TestMe');
        $stub->expects ($this->exactly(2))->method('method');
        $stub->method();
    }

    public function testC()
    {
        $stub = $this->getMock ('TestMe');
        $stub->expects ($this->exactly(2))->method('method');
        $stub->method();
        $stub->method();
    }

    public function testD()
    {
        $stub = $this->getMock ('TestMe');
        $stub->expects ($this->exactly(2))->method('method');
        $stub->method();
        $stub->method();
        $stub->method();
    }
}

testA、testB、testC 通过，testD 仅失败，这很奇怪。 testA 甚至没有调用该方法，所以它应该失败了——但它通过了，为什么？ testB 调用该方法一次，但我们预期调用两次，所以它应该失败了——但它通过了，为什么？ testC没问题，没问题 testD 失败所以没问题

也许 exactly() 并没有像我预期的那样工作。我正在使用最新的 4.3.4 PhPunit。

尝试在 getMock 调用中添加您要模拟的方法名称。

为了获得方面的结果，我将测试类修改为:

class TestTest extends \PHPUnit_Framework_TestCase
{
    public function testA()
    {
        $stub = $this->getMock ('TestMe',array('method'));
        $stub->expects ($this->exactly(2))->method('method');
    }

    public function testB()
    {
        $stub = $this->getMock ('TestMe',array('method'));
        $stub->expects ($this->exactly(2))->method('method')->withAnyParameters();
        $stub->method();
    }

    public function testC()
    {
        $stub = $this->getMock ('TestMe',array('method'));
        $stub->expects ($this->exactly(2))->method('method')->withAnyParameters();
        $stub->method();
        $stub->method();
    }

    public function testD()
    {
        $stub = $this->getMock ('TestMe',array('method'));
        $stub->expects ($this->exactly(2))->method('method')->withAnyParameters();
        $stub->method();
        $stub->method();
        $stub->method();
    }
}

结果是:

PHPUnit 4.3.4 by Sebastian Bergmann.

There were 3 failures:

1) Acme\DemoBundle\Tests\TestTest::testA
Expectation failed for method name is equal to <string:method> when invoked 2 time(s).
Method was expected to be called 2 times, actually called 0 times.

2) Acme\DemoBundle\Tests\TestTest::testB
Expectation failed for method name is equal to <string:method> when invoked 2 time(s).
Method was expected to be called 2 times, actually called 1 times.

3) Acme\DemoBundle\Tests\TestTest::testD
TestMe::method() was not expected to be called more than 2 times.

希望对你有帮助
