给出您要求的答案（使用JMockit的部分模拟）：
public class MyClassTest{ @Tested MyClass myClass; @Test public void test_MyClass_methodA_enters_if_condition() { final CustomObject object1 = new CustomObject("input1"); final CustomObject object2 = new CustomObject("input2"); new NonStrictExpectations(myClass) {{ invoke(myClass, "methodB", object1, object2); result = true; }}; assertEquals("Result", myClass.methodA(object1, object2)); } @Test public void test_MyClass_methodA_skips_if_condition() { final CustomObject object1 = new CustomObject("input1"); final CustomObject object2 = new CustomObject("input2"); new NonStrictExpectations(myClass) {{ invoke(myClass, "methodB", object1, object2); result = false; }}; assertEquals("Different Result", myClass.methodA(object1, object2)); }}但是，我 不 建议这样做。通常，
private不应模拟方法。而是模拟被测单元的实际外部依赖关系（
CustomObject在这种情况下）：
public class MyTestClass{ @Tested MyClass myClass; @Mocked CustomObject object1; @Mocked CustomObject object2; @Test public void test_MyClass_methodA_enters_if_condition() { new NonStrictExpectations() {{ Something thing = new Something(); object1.getSomething(); result = thing; object2.getSomething(); result = thing; }}; assertEquals("Result", myClass.methodA(object1, object2)); } @Test public void test_MyClass_methodA_skips_if_condition() { new NonStrictExpectations() {{ object1.getSomething(); result = new Something(); object2.getSomething(); result = new Something(); }}; assertEquals("Different Result", myClass.methodA(object1, object2)); }}
