我的受试者中有以下代码:
public class Widget {
private Set<Thing> things;
public Set<Thing> getThings() { return things; }
public void setThings(Set<Thing> things) { this.things = things; }
public void performAction(PerformingVisitor performer) {
for (Thing thing: getThings())
{
thing.perform(performer);
}
}
}
我的JUnit/Mockito测试看起来像:
@RunWith(MockitoJUnitRunner.class)
public class WidgetTest {
@Mock private PerformingVisitor performer;
@Mock private Thing thing;
@InjectMocks private Widget widget;
@Before
public void setUp() throws Exception {
Set<Thing> things = new HashSet<Thing>();
things.add(thing);
widget.setThings(things);
MockitoAnnotations.initMocks(this);
}
@Test
public void shouldPerformThing() {
Mockito.when(thing.perform(Mockito.any(PerformingVisitor.class))).thenReturn(true);
widget.performAction(performer);
Mockito.verify(thing).perform(Mockito.any(PerformingVisitor.class));
}
}
然而,这给了我一个错误:
Wanted but not invoked:
thing.perform(<any>);
-> at com.myclass.ThingTest.shouldPerformThing(WidgetTest.java:132)
我已经验证了代码进入了for
循环,并且应该调用实际的thing.perform(performer);
行,但我的mock似乎没有记录调用。
我认为在模拟注入之前需要initMocks
。
你能试着改变你的设置方法吗:
@Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
Set<Thing> things = new HashSet<Thing>();
things.add(thing);
widget.setThings(things);
}
希望它能在上运行
来自MockitoJUnitRunner
javadoc:
初始化用Mock注释的Mock,这样就不需要显式使用MockitoAnnotations.initMocks(Object)。
所以,如果你删除
MockitoAnnotations.initMocks(this)
从您的setUp
方法,测试通过。
