Mock partial static method with PowerMockito

我們可以透過PowerMock的mockStaticPartial去mock部分的static method:

		PowerMock.mockStaticPartial(System.class, "getProperty");
 
		System.getProperty("test");
		PowerMock.expectLastCall().andReturn("test").anyTimes();
 
		PowerMock.replayAll();
 
		System.out.println(System.getProperty("test"));
 
		PowerMock.verifyAll();

如果想用PowerMockito該如何做呢? 我們可以使用spy:

		PowerMockito.spy(System.class);
		PowerMockito.doReturn("test").when( System.class, "getProperty", "test");
 
		System.out.println(System.getProperty("test"));

另一種寫法如下:

		PowerMockito.spy(System.class);
		PowerMockito.doReturn("test").when( System.class);
		System.getProperty("test");
 
		System.out.println(System.getProperty("test"));
 
		PowerMock.verifyAll();

如果是沒任何回傳值的method，可以使用PowerMockito.doNothing()。

友藏內心獨白: 實際應用會遇到更多問題的!

• Use doReturn to partially mock static method with PowerMockito
• Is it possible to use partial mocking for private static methods in PowerMock?
