验证时，Powermock比实际调用计数更多

Question

是Powermock的错误还是我做错了什么?

下面的测试应该通过，但是失败了:

trackBugPartialMockCountMore(com.xiaomi.finddevice.test.testcase.PowerMockBug)
org.mockito.exceptions.verification.TooManyActualInvocations: 
classToMock.foo();
Wanted 1 time:
-> at com.xiaomi.finddevice.test.testcase.PowerMockBug.trackBugPartialMockCountMore(PowerMockBug.java:24)
But was 3 times. Undesired invocation:
-> at com.xiaomi.finddevice.test.testcase.PowerMockBug.trackBugPartialMockCountMore(PowerMockBug.java:22)

当我删除@PrepareForTest(ClassToMock.class)，一切都很顺利，测试通过了。

import org.junit.Ignore;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import static org.mockito.Mockito.verify;
import static org.powermock.api.mockito.PowerMockito.mock;
import static org.powermock.api.mockito.PowerMockito.when;
@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassToMock.class)
public class PowerMockBug {
    @Test
    public void trackBugPartialMockCountMore() {
        ClassToMock mock = mock(ClassToMock.class);
        when(mock.foo()).thenCallRealMethod();
        mock.foo();
        verify(mock).foo();
    }
}

class ClassToMock {
    public int foo() { return 0x10; }
}

版本:powermock-mockito-junit-1.6.3

在您的示例中，您不需要使用PowerMock，因为您没有模拟/监视final或静态方法。你可以安全地删除@RunWith和@PrepareForTest注释。您只需要mockito
