通缉但未调用 Mockito

Question

您好，我的testRegLogin() 测试出现"Wanted but not invoked" 错误，但是我的其余测试都通过了。 我的测试如下。此代码测试Login.java 代码，该代码检查输入JTextField 的详细信息，然后根据数据库检查它们。如果发生正确登录，它会调用 Controller 类。

Answer 1

Mockito 在您的 testRegLogin() 方法中告诉您您期望 login.register() 被调用一次，但 Mockito 告诉您它从未被调用过。您可以通过更改来验证这一点

verify(login, times(1)).register();

到

verify(login, never()).register();
