Gradle multi project - sharing test code between modules

Question

ProjectA contains an abstract unit test, TestA.

ProjectB has a test called TestB, which needs to extends from TestA, to fulfil the test requirements for this specific implementation.

I've added to the build.gradle configuration file on ProjectB, ProjectA as a dependency compilation test:

testCompile project(':ProjectA')

Also, as a dependency compilation:

compile project(':ProjectA')

Although I'm able to extend from TestA, when I try to run TestB I get the next error:

error: cannot find symbol class TestA

So, is there any way to share test code between modules?

Thanks.

Did you add include under the settings file for the root project? — Daniel, Jun 17 '16 at 23:19
You mean if in the top level build.gradle are defined as dependencies both modules? If so, yes, I did that. — Víctor Albertos, Jun 17 '16 at 23:25
The settings.gradle file for project B should have something like include ':projectA'. — Daniel, Jun 17 '16 at 23:28

As mentioned in this question you should add dependency on test sources like this:

compileTestJava.dependsOn tasks.getByPath(':projectA:testClasses')
testCompile files(project(':projectA').sourceSets.test.output.classesDir)

Can you give an example for how to do this for `androidTest`s with kotlin? – B W Apr 25 '18 at 21:30
This is incorrect: 1) The second line implies the first; you don't need both. 2) This will result in the tests from projectA also being run in this project – David Nelson Jul 24 '18 at 14:44
Updated example to the latest Gradle version? – kylie.zoltan Jan 11 '23 at 14:06
