How to share resources between unit test and instrumentation test in android?

问题

I'm following this post, http://blog.danlew.net/2015/11/02/sharing-code-between-unit-tests-and-instrumentation-tests-on-android/, to share code, but how to share an asset?, like a fixture file?, I want to mock an api response, so I have a JSON file to do it, but I try this: https://gist.github.com/nebiros/91a68aaf6995fa635507

In Unit Test, this works:

ClassLoader.getSystemResourceAsStream("some_response.json");

but in Android Intrumentation Tests, it doesn't, where can I put those fixture files?.

I found this way, to share fixture files from test to androidTest:

• Add your fixture files to the resources folder of your test one, here: src/test/resources.

• Add test resources folder to androidTest, resources.srcDirs += ['src/test/resources'], here's an example:

  android {
      sourceSets {
          String sharedTestJavaDir = 'src/sharedTest/java'
  
          test {
              java.srcDirs += [sharedTestJavaDir]
          }
  
          androidTest {
              java.srcDirs += [sharedTestJavaDir]
              resources.srcDirs += ['src/test/resources']
          }
      }
  }
  

• Access fixture files from your androidTest env this way: this.getClass().getClassLoader().getResourceAsStream(filename);
