@Test

        MainActivity mainActivity = PowerMockito.mock(MainActivity.class);
        PowerMockito.when(mainActivity.checkStringPrivate()).thenCallRealMethod();
        PowerMockito.when(mainActivity, "isOkPrivate").thenReturn(true);//isOkPrivate是私有方法，但是模拟了MainActivity，可以通过公有方法间接调用测试
        Assert.assertTrue(mainActivity.checkStringPrivate());
