我有以下测试方法:
@RunWith(MockitoJUnitRunner.class)
public class AccountManagerTest {
@InjectMocks
private AccountManager accountManager = new AccountManagerImpl(null);
@Mock
private AuthStorage authStorage;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
}
/* REGISTER TESTS */
@Test
public void test_whenRegister_withAlreadyExistingEmail_thenDoNotRegister() throws AuthStorageException {
String email = "foo@bar.com";
String name = "Foo";
String password = "123456";
String password2 = "123456";
doThrow(new AuthStorageException("Email already in use")).when(authStorage).registerNewUser(Matchers.any());
assertFalse(accountManager.register(email, name, password, password2));
}
}
测试以下类方法:
@Override
public Boolean register(String email, String name, String password, String password2) {
if (password.equals(password2)) {
try {
String pwd = hashPassword(password);
User user = new User(email, name, pwd);
AuthStorage authStorage = new AuthStorageImpl();
authStorage.registerNewUser(user);
return true;
} catch (NoSuchAlgorithmException | AuthStorageException e) {
return false;
}
}
// If passwords don't match
return false;
}
据推测,当调用 registerNewUser
时它应该抛出一个异常然后该方法将返回 false
,但是在调试时我发现没有抛出异常并且程序返回 true
。我做错了什么?
最佳答案
首先你不应该实例化插入模拟的对象:
@InjectMocks
private AccountManager accountManager = new AccountManagerImpl(null);
相反,使用这个:
@InjectMocks
private AccountManager accountManager;
然后如果你使用 Mockito runner:
@RunWith(MockitoJUnitRunner.class)
你不应该直接注入(inject)模拟:
@Before
public void setup() {
MockitoAnnotations.initMocks(this); //remove this line
}
最后一点:您的模拟没有意义,因为您的 register 方法中有一个局部变量:
AuthStorage authStorage = new AuthStorageImpl();
authStorage.registerNewUser(user);
这使得该类使用您的模拟对象。
