Question

public class Service1 {

private Service2 service2;

// FunctionA
private FuncA(Object1 obj1) {

    /*
    code to make Obj2 from Obj1
    */

    service2.FuncB(obj2);
  }

}

public class Service2 {
  // FunctionB
  private FuncB(Object2 obj) {
    obj.field=value;  
  }

}

我正在尝试为Func A编写单元测试用例（如上所述），并且需要模拟Func B（如上所述）。 PLS。帮助我如何在Java 7中做到这一点。

您需要将要测试的service2类中的Service1成员设置为模拟框架创建的模拟对象。这看起来像这样：

public class Service1Test {

    @Mock
    private Service2 service2;

    @InjectMocks // service2 mock will be injected into service1
    private Service1 service1;

    @Before
    public void setUp() throws Exception {
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void doTest() {

        Object someObject = null; // create object matching your needs
        service1.FuncA(someObject);

        Object someOtherObj = null; // create object matching your needs
        verify(service2, times(1)).FuncB(someOtherObj);

        // perform additional assertions
    }
}

如何模拟一个在java中没有返回任何内容的函数
