Question

我正在尝试mockito.verify（）功能，方法调用仅一次，但是验证显示调用3次。单元测试只有一个测试，以确保该测试不会受到其他影响。 Mockito.verify（utilClass，Mockito.times（1））。hello（）; ///但调用是3次，是错误

我尝试使用日志，该日志显示调用一次。多次添加了故意调用方法utilClass.hello（），然后显示正确的调用次数。但是在给定的代码中，一次调用被显示为被调用3次。

要测试的类：

@Component
public class UtilClass {

    private static final Logger logger =  LoggerFactory.getLogger(UtilClass.class);

    public String hello() {
        logger.info("hello method invoked");
        return "Hello World,"+ hi();
    }

    private String hi() {
        logger.info("hi method invoked");
        return "Hi All";
    }
}
@Component
public class ClassWithDependency {

    @Autowired
    private UtilClass utilClass;

    public String welcome() {
        String msg = utilClass.hello();
        return msg;
    }

}

测试用例


@InjectMocks
private ClassWithDependency classWithDependency;

@Mock
private UtilClass utilClass;

@Before
public void init() throws Exception {
        PowerMockito.when(utilClass,"hi").thenReturn("Hi Java");
        PowerMockito.when(utilClass.hello()).thenCallRealMethod();
    }


    @Test
    public void testMock() throws Exception {
        final String msg = classWithDependency.welcome();

        final String msgExpected = "Hello World,Hi Java";
        logger.info("welcome method called:{}",msg);

        PowerMockito.verifyPrivate(utilClass, Mockito.times(1)).invoke("hi");
        Mockito.verify(utilClass, Mockito.times(1)).hello();

        Assert.assertTrue(msg.equals(msgExpected));
    }

我希望mockito.verify成功，但会出错

org.mockito.exceptions.verification.TooManyActualInvocations： utilClass.hello（）; 想要1次： -> com.sd.demo.powermock.test.injectmock.InjectMockTest.testMock（InjectMockTest.java:54）但是是3次： -> com.sd.demo.powermock.injectmock.ClassWithDependency.welcome（ClassWithDependency.java:13） -> com.sd.demo.powermock.injectmock.ClassWithDependency.welcome（ClassWithDependency.java:13） -> com.sd.demo.powermock.injectmock.ClassWithDependency.welcome（ClassWithDependency.java:13）在com.sd.demo.powermock.test.injectmock.InjectMockTest.testMock（InjectMockTest.java:54）在org.junit.internal.runners.TestMethod.invoke（TestMethod.java:68）在org.junit.internal.runners.MethodRoadie $ 2.run（MethodRoadie.java:89） .............

最后使测试正常工作，解决方案是'SPY'..间谍util类，以便不告诉哪个方法进行真正的调用。我不确定如何注入间谍，所以使用了二传手。

@InjectMocks 私人ClassWithDependency classWithDependency;

private UtilClass mockUtil;

@Before
public void init() throws Exception {
    UtilClass utilClass = new UtilClass();
    mockUtil = PowerMockito.spy(utilClass);
    classWithDependency.setUtilClass(mockUtil); 
}

@Test
public void testMock() throws Exception {
    PowerMockito.when(mockUtil,"hi").thenReturn("Hi Java"); 
    final String msg = classWithDependency.welcome();
    final String msgExpected = "Hello World,Hi Java";
    logger.info("welcome method called:{}",msg);
    PowerMockito.verifyPrivate(mockUtil, Mockito.times(1)).invoke("hi");
    Mockito.verify(mockUtil, Mockito.times(1)).hello();
    Assert.assertTrue(msg.equals(msgExpected));
}

mockito.veify（）给出错误的调用计数
