Junit4和Jmock

Question

我已经检查了所有关于这方面的堆栈溢出问题。但我找不到合适的解决方案。

public class TestAuthenticate {
private RestService rs;
private String token_actual = token1;
private Mockery context;
private Authenticate authenticate_object;


@Before
public void setup(){
context = new JUnit4Mockery() {{
    setImposteriser(ClassImposteriser.INSTANCE);
}}; 

rs = new RestService();
}

@Test
public final void testAuthenticate() {

    authenticate_object = context.mock(Authenticate.class);

    context.checking(new Expectations() {
        {
            oneOf(authenticate_object).authenticate_method("username", "password");
            will(returnValue(token1));
        }
     });
    String token = rs.authenticate("username", "password");
    System.out.println(token);

    assertEquals(token_actual, token);
    context.assertIsSatisfied();
}

}

这是调用实际的身份验证方法，而不是模拟身份验证类。谁能告诉我我哪里做错了？

public class RestService {
public string authenticate(String user, String pass){
Authenticate auth = new Authenticate();
String res = auth.authenticate(user,pass);
}
return res;
}

Answer 1

通常，您将使用某种形式的依赖项注入将模拟AuthenticationService注入到RestService中。试着重写你的RestService，比如

public class RestService {
    private final AuthenticateService auth;
    public RestService(AuthenticateService auth) {
       this.auth = auth;
    } 
    public string authenticate(String user, String pass){
        return auth.authenticate(user,pass);
    }
}

然后在你的测试中

 rs = new RestService(authenticate_object);
