java - JMockit 没有。 API 调用次数

Question

我正在测试当异常发生时 doSomething 方法是否再次在 catch block 中被调用。如何验证“doSomething”是否被调用了两次？

要测试的类:

@Service
public class ClassToBeTested implements IClassToBeTested {

@Autowired
ISomeInterface someInterface;

public String callInterfaceMethod() {
 String respObj;
 try{
     respObj = someInterface.doSomething(); //throws MyException
 } catch(MyException e){
    //do something and then try again
    respObj = someInterface.doSomething();
 } catch(Exception e){
    e.printStackTrace();
  }
 return respObj;
 }
}

测试用例:

public class ClassToBeTestedTest
{
@Tested ClassToBeTested classUnderTest;
@Injectable ISomeInterface mockSomeInterface;

@Test
public void exampleTest() {
    String resp = null;
    String mockResp = "mockResp";
    new Expectations() {{
        mockSomeInterface.doSomething(anyString, anyString); 
        result = new MyException();

        mockSomeInterface.doSomething(anyString, anyString); 
        result = mockResp;
    }};

    // call the classUnderTest
    resp = classUnderTest.callInterfaceMethod();

    assertEquals(mockResp, resp);
}
}

Answer 1

以下应该有效:

public class ClassToBeTestedTest
{
    @Tested ClassToBeTested classUnderTest;
    @Injectable ISomeInterface mockSomeInterface;

    @Test
    public void exampleTest() {
        String mockResp = "mockResp";
        new Expectations() {{
            // There is *one* expectation, not two:
            mockSomeInterface.doSomething(anyString, anyString);

            times = 2; // specify the expected number of invocations

            // specify one or more expected results:
            result = new MyException();
            result = mockResp;
        }};

        String resp = classUnderTest.callInterfaceMethod();

        assertEquals(mockResp, resp);
    }
}
