如何为 PHPUnit Mock 重置 expects()?
我有一个 SoapClient 的模拟,我想在测试中多次调用它,重置每次运行的期望值。
$soapClientMock = $this->getMock('SoapClient', array('__soapCall'), array($this->config['wsdl']));
$this->Soap->client = $soapClientMock;
// call via query
$this->Soap->client->expects($this->once())
->method('__soapCall')
->with('someString', null, null)
->will($this->returnValue(true));
$result = $this->Soap->query('someString');
$this->assertFalse(!$result, 'Raw query returned false');
$source = ConnectionManager::create('test_soap', $this->config);
$model = ClassRegistry::init('ServiceModelTest');
// No parameters
$source->client = $soapClientMock;
$source->client->expects($this->once())
->method('__soapCall')
->with('someString', null, null)
->will($this->returnValue(true));
$result = $model->someString();
$this->assertFalse(!$result, 'someString returned false');
最佳答案
经过更多调查,您似乎只是再次调用了 expect()。
然而,这个例子的问题在于 $this->once() 的使用。在测试期间,无法重置与 expects() 关联的计数器。为了解决这个问题,您有几个选择。
第一个选项是忽略它被 $this->any() 调用的次数。
第二个选项是使用 $this->at($x) 来定位调用。请记住 $this->at($x) 是模拟对象被调用的次数,而不是特定方法,并且从 0 开始。
以我的具体例子来说,因为mock test两次都是一样的,预计只会被调用两次,所以我也可以使用$this->exactly(),只有一个expects()语句。即
$soapClientMock = $this->getMock('SoapClient', array('__soapCall'), array($this->config['wsdl']));
$this->Soap->client = $soapClientMock;
// call via query
$this->Soap->client->expects($this->exactly(2))
->method('__soapCall')
->with('someString', null, null)
->will($this->returnValue(true));
$result = $this->Soap->query('someString');
$this->assertFalse(!$result, 'Raw query returned false');
$source = ConnectionManager::create('test_soap', $this->config);
$model = ClassRegistry::init('ServiceModelTest');
// No parameters
$source->client = $soapClientMock;
$result = $model->someString();
$this->assertFalse(!$result, 'someString returned false');
Kudos for this answer that assisted with $this->at() and $this->exactly()
