java - PowerMock で同じクラスの void 静的メソッドと静的メソッドを抑制する

Question

私は現在、PowerMock 1.4.10 を使用していくつかのレガシー コードで単体テストを行おうとしていますが、静的な void 呼び出しと静的な非 void 呼び出しの両方を持つテストしようとしているメソッドがあります。静的な void 呼び出しを抑制しながら、静的な非 void 呼び出しをモックする方法はありますか?

@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassUnderTest.class)
public class TestClass {

    @Test
    public void test() {
        MemberModifier.suppress(StaticClass.class.getDeclaredMethod("logRandom"));

        PowerMock.mockStatic(StaticClass.class);
        expect(StaticClass.isLogOn()).andReturn(true);
        PowerMock.replay(StaticClass.class);

        ClassUnderTest test = new ClassUnderTest();
        test.methodToTest();

        assertTrue(test.tested);

        PowerMock.verify(StaticClass.class);
    }
}


public class ClassUnderTest {
    public boolean tested = false;

    public void methodToTest() {
        if (StaticClass.isLogOn()) {
            StaticClass.logRandom();
        }
    }

}

public class StaticClass {

    public static void logRandom() {
        System.out.println("Do something");
    }

    public static boolean isLogOn() {
        return (Math.random() > .5);
    }
}

しかし、これを実行しようとすると、次の stackTrace が表示されます。

これに対処する方法についてのアイデアはありますか？
