如何在功能模块中对 Android 资源进行单元测试？

Question

My app is using feature modules. One of the feature modules declares a bunch of strings in an xml resource, and then accesses them from my kotlin code: eg getString(R.string.dialog_title) . I want to run Junit tests to prove that the correct string content is retrieved.

The Robolectric documentation page suggests using the function getApplicationContext<MyApplication>() . However, you don't have access to the Application when unit testing a feature module. I guess that's because feature modules exist separately to the application?

Any help appreciated. :)

Robolectric will slow your unit tests a bit. You can just mock context object and then do something like: when(context.getString(any()).thenReturn('any/empty string')
