asp.net-core - 如何从单元测试访问 IApplicationEnvironment？

Question

如何从 xUnit 2 单元测试访问 IApplicationEnvironment？

我认为在多种情况下我需要这个，包括:

• 从使用单元测试构建的非嵌入式配置文件中读取
• 创建并编写与单元测​​试相关的文件

嗯，这并不理想，但你可以使用 the static service locator到达它:

var appEnv = CallContextServiceLocator.Locator.ServiceProvider
    .GetService(typeof(IApplicationEnvironment)) as IApplicationEnvironment;

I am not sure if xUnit injects framework dependencies in through the constructor and I bet it doesn't. If it does though (which would be perfect), you can just inject it into the test class through its constructor.
