Test Component accessible from src/test/java and src/androidTest/java

[James S]

Hi guys,

I have have an app that uses Dagger 2.0.1, Robolectric 3.0, Espresso 2.2.1.

My app has both src/test/ folder (for Robolectric and unit tests) and src/androidTest (for Espresso and unit tests). There are 2 build types in Gradle: release (no test code included) and debug (includes test code). Currently I have a single Dagger AppComponent in /src/main/java

question 1: What is the best practice about adding a TestAppComponent? Would I place it under  src/androidTest or  src/test? What I like to do is to be able to access it from both types of tests.

question 2: I cannot seem to generate a Dagger code for TestAppComponent when I place my component code annotated with @Component under either src/androidTest or  src/test.  What gradle task would I run to generate Dagger code?

Thanks for any help!

Q1 - AFAIK android studio 2.0 allows you to share code between both types of test project

[Jake Wharton]

It allows both source sets to be active for refactoring purposes. You have always been able to share code between the two by adding a folder to both source sets. Example: http://blog.danlew.net/2015/11/02/sharing-code-between-unit-tests-and-instrumentation-tests-on-android/

Regarding your second question, you probably need to have the Dagger compiler run in the androidTest or test scope. I imagine the apt gradle plugin has an androidTestApt or testApt accordingly
