Android 测试依赖于库项目上的测试类

Question

so my project has two modules:

• app
• library

In the addroidTest directory of the app, I have some classes that depends on classes located in the addroidTest directory of the library.

The structure is:

:library /src/main
            /androidTests

:app     /src/main
            /androidTests

They compile finely in Android Studio, but when I run the tests I get:

Error:(6, 32) error: cannot find symbol class XXXX Error:Execution failed for task [...]

Compilation failed; see the compiler error output for details.

[....]

Execution failed for task > ':app:compileProductionDebugAndroidTestJavaWithJavac'.

It seems that when gradle executes the task ':app:compileProductionDebugAndroidTestJavaWithJavac' it cannot find classes located in the test directory of the library.

Any idea how can I solve this?

Answer 1

test source sets are not added to the outputted jar and therefore do not exist when app looks for library code in androidTest . You can place your shared classes in the main lib code and reference it from your app there, but I don't think it's possible for you to depend|extend on test classes of another module.

Answer 2

I've worked with Junit and it was located in libs folder as you mentioned. for your test classes you can try these steps:

1- in androidTest folder, make sure you place your test classes in a path like this: androidTest -> java -> com.examples.bla (the same as the project) ->the test class.

2- Go to run/debug configuration ->defaults -> Android Tests (add it if it's not there), then choose "All in Module" for test option, and also make sure that Gradle-aware Make is added at the bottom of the configuration window.
