unit-testing - 在Grails中模拟mixin类

Question

我在对 Controller 进行单元测试时遇到了一些困难。

我有以下对象:

class User {
    String username
}

class SecurityMixin {

    User userDetails(session) {
        User user = new User()
        user.username = 'somename'
        return user
    }
}

@Mixin(SecurityMixin)
class MyController {
    def index() {
        def username = userDetails(session).username

    }
}

我将如何模拟userDetails方法？

Answer 1

我从未用过mixin做到这一点，也许您可​​以测试一下。在您的* ControllerTests中

@Before
void setUp() {
  ..
  controller.metaClass.userDetails = {
    new User(username: 'somename')
  }
}
