使用Mockito，如何验证方法是否具有某个参数？ [英] Using Mockito, how do I verify a method was a called with a certain argument?

问题描述

我正在使用Mockito 1.9.0。我如何验证一个方法只被调用一次，并且传递给它的一个字段包含一定的值？在我的JUnit测试中，我有

I'm using Mockito 1.9.0. How would i verify that a method got called exactly once, and that one of the fields passed to it contained a certain value? In my JUnit test, I have

@Before
public void setupMainProg() { 
    // Initialize m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc
    ...
    m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
}   // setupMainProg

@Test
public void testItAll() throws GeneralSecurityException, IOException { 
    m_prog.work();  
}

方法work调用方法m_orderSvc（其中一个传递给对象的参数）。 m_orderSvc又包含一个成员字段m_contractsDao。我想验证m_contractsDao.save只被调用一次，并且传递给它的参数包含一个特定值。

The method "work" calls a method of "m_orderSvc" (one of the arguments passed in to the object). "m_orderSvc," in turn contains a member field, "m_contractsDao". I want to verify that "m_contractsDao.save" got called exactly once and that the argument passed to it contains a certain value.

这可能有点令人困惑。让我知道如何澄清我的问题，我很高兴这样做。

This may be a little confusing. Let me know how I can clarify my question and I'm happy to do so.

推荐答案

首先你需要创建一个模拟m_contractsDao并进行设置。假设该类是ContractsDao：

First you need to create a mock m_contractsDao and set it up. Assuming that the class is ContractsDao:

ContractsDao mock_contractsDao = mock(ContractsDao.class);
when(mock_contractsDao.save(any(String.class))).thenReturn("Some result");

然后将模拟注入m_orderSvc并调用您的方法。

Then inject the mock into m_orderSvc and call your method.

m_orderSvc.m_contractsDao = mock_contractsDao;
m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
m_prog.work(); 

最后，确认模拟被正确调用：

Finally, verify that the mock was called properly:

verify(mock_contractsDao, times(1)).save("Parameter I'm expecting");
