我有这个Java代码:
@Service
public class TestService {
@Inject
private AnotherClass anotherClass;
public boolean isEnabled() {
return anotherClass.getSomeValue().equals("true");
}
}
然后我有了Groovy测试类:
class TestServiceTest {
@Mock
private AnotherClass anotherClass;
private TestService testService;
@Before
void initMock() {
MockitoAnnotations.initMocks(this)
testService = new TestService()
}
void isEnabledTest() {
when(anotherClass.getSomeValue()).thenReturn("true")
assert testService.isEnabled() == true;
}
}
上面的测试是在Java类中的anotherClass.getSomeValue()语句上引发java.lang.NullPointerException。看起来TestClass已正确设置。我不明白问题出在哪里。
您需要注入您的模拟。只需添加@InjectMocks
到私有TestService testService;
您将不需要 testService = new TestService();
class TestServiceTest {
@Mock
private AnotherClass anotherClass;
@InjectMocks
private TestService testService;
@Before
void initMock() {
MockitoAnnotations.initMocks(this)
}
void isEnabledTest() {
when(anotherClass.getSomeValue()).thenReturn("true")
assert testService.isEnabled() == true;
}
}
