解析器的AutoMapper测试和依赖项注入

Mat*_*teS 6 ioc-container automapper

我正在为自动映射器地图编写测试。映射中的目标成员之一需要一个值解析器,并且该值解析器具有注入的服务依赖项。我想为解析器使用真正的实现(因为那是map im测试的一部分),但我想对解析器具有的依赖项使用模拟。

当然,我想避免在测试中使用ioc容器,但是如何在没有容器的情况下轻松解决我的价值解析器的依赖性呢?

这是我相当简化的示例,在实际情况下,有几个解析器有时带有很多依赖关系,我真的不喜欢在测试中基本上实现自己的依赖解析器。我应该使用轻质的ioc容器吗?

这是一种解决方案,但基本上是 iv 已经完成的:

建议使用服务定位器,该定位器根据测试或实际实施而设置不同。
