如何使用PowerMockito模拟从构造函数调用的私有方法

@RunWith(PowerMockRunner.class)
@PrepareForTest(YourClass.class)
public class YourClassTest {
    // 测试方法
}

@Test
public void testPrivateMethod() throws Exception {
    YourClass instance = PowerMockito.spy(new YourClass());
    PowerMockito.when(instance, "privateMethod").thenReturn("mockedValue");
    
    // 调用被测试方法
    String result = instance.methodUnderTest();
    
    // 断言结果
    assertEquals("mockedValue", result);
}
