AndroidX espresso tests not running, Tried a sample app and can make it work, not on a scaled project with many modules

Issue

I have a scaled project that has at least 12 modules. I would like to start the app module and run the project. Every time I try to start it, I keep getting the message that

$ adb shell CLASSPATH=$(pm path androidx.test.services) app_process / androidx.test.services.shellexecutor.ShellMain am instrument -r -w -e targetInstrumentation *** ... *** androidx.test.orchestrator/androidx.test.orchestrator.AndroidTestOrchestrator
Client not ready yet..
Started running tests
Test running failed: No test results. 

I read through the AndroidX documentation of espresso usage and have

• included the ANDROIDX_TEST_ORCHESTRATOR
• have included the required libraries using the useLibrary function
• set up the test runner to use androidx-testRunner.

I was able to generate the tests using the Espresso test runner but every time I try to run it, I get this message. Just to be sure I made a sample app and tested the whole thing out and I am able to make instrumentation tests on the sample app.

Does anyone know what could happen in a multi-module project that uses dependency injection?

Solution

It had nothing to do with modules or project size, removing the ANDROIDX_TEST_ORCHESTRATOR made it work.
