PHPUnit的，期望的方法恰好運行兩次

Question

class TestMe 
{ 
    public function method() { } 
} 

測試：

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(); 
    } 
} 

種皮，TESTB，TESTC流逝，僅TESTD失敗，這是奇數。 testA甚至沒有調用方法，所以它應該失敗 - 但它通過了，爲什麼？ testB調用方法ONCE，但我們預計TWICE應該失敗 - 但它通過了，爲什麼？ testC是好的，沒問題 testD因此無法正常工作，沒問題

也許正好（）並不能完全符合我的預期。我使用最新的4.3.4 PhPunit。

嘗試在getMock調用中添加想要模擬的方法名稱。

爲了獲得aspected結果我修改測試類爲：

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(); 
    } 
} 

，其結果是：

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. 

希望這有助於
