Question

我有一个片段，它从另一个Util类调用静态方法。

 public class DummyFragment extends Fragment {

    public void dummyMethodCall(){
      UtilClass.dummyStaticMethod(Arg arg);
    }

 }

如何使用PowerMockito验证在Mockito测试中是否已调用UtilClass.dummyStaticMethod（）？以下是我当前的测试：

    @RunWith(RobolectricGradleTestRunner.class)
    @PowerMockIgnore({"org.mockito.*", "org.robolectric.*", "android.*"})
    @Config(constants = BuildConfig.class, sdk = 19, packageName = "com.dummy.package", application = DummyApplication.class)
    @PrepareForTest({UtilClass.class})
    public class FragmentTest {

    private DummyFragment mDummyFragment;

    @Rule
    public PowerMockRule rule = new PowerMockRule();

    @Before
    public void setUp() {
        mDummyFragment = new DummyFragment();
    }

    @Test
        public void dummyMethodCall_success() {

            PowerMockito.mockStatic(UtilClass.class);
            mDummyFragment.dummyStaticMethod();
            PowerMockito.verifyStatic();
        }

    }

如果要检查它是否在实际测试中调用，可以在您的UtilClass中添加一个布尔静态成员，您在dummyStaticMethod（）中设置为true，然后在测试中调用后检查该值。

如果您只想检查它是否有用于调试目的，可以在调试模式下运行并在dummyStaticMethod中设置断点，或者将System.out.print添加到方法中。
