Question

单元测试：

class OtherServiceSpec extends Specification {
    def fooCacheService = Mock(FooCacheService)
    ...
}

服务：

class FooCacheService extends CacheService<String> {
    ...
}

通用基类：

class CacheService<T> {
    ...
}

堆栈追踪：

Answer 1

我没有得到任何解释为什么会发生这种情况。我只是观察到Mock（）在模拟接口的实现时遇到了问题。

我通过模拟界面解决了这个问题。所以在你的情况下，你应该用这个命令构建你的模拟：

def cacheService = Mock(CacheService)

这当然也意味着您还必须使用 CacheService 接口而不是FooCacheService来实现您所讨论的类（ OtherService ）。

希望这有帮助。
