Android: Virtual Device Testing on multiple modules

I have instrumentation tests in about 5 different gradle modules. Each should be run with different build flavors.

The current setup just allows instrumentation tests for (simple?) projects which rely on a single module.

It would be great if this structure would be supported.

Thanks for the #feature-request @PaulWoitaschek!

Possible workarounds in the meantime (if you’d have to run instrumentation tests on Firebase TestLab for multiple separate APKs/modules):

If you’d have any questions just let us know! :wink:

Another work around is to use parallel flows: https://blog.bitrise.io/start-multiple-builds-with-the-same-trigger

Hi @viktorbenei, do you have a solution in the workings for this?

I’d like to run UI tests (Virtual Device Tests) for two different build flavors in the same module. However, this also produces two different APK files.

Unless your account allows for build parallelization, I guess the only option still is to create a separate App for each build flavor that needs Virtual Device Testing?

Cheers,

Hy!

there is no need for 2 separate apps, use 2 separate workflows with workflow specific env vars to specify which one you would like to run.

Hi @fehersanyi-bitrise!

This works if we run the workflow after the other, or only if we have parallel workflows?

Cheers

Hy👋

only works if they are run after another, because on the same app you can’t run 2 firebase tests parallel unfortunately.

Hi again @fehersanyi-bitrise.

I tried to do that but unfortunately I’m still getting the same error (Failed to start test: 403, error: {“error”:“Build already exists”}).

Maybe I misunderstood something or I’m doing something wrong.

This is my bitrise.yml:

I encountered the same situation, and it seems that bitrise doesn’t support multiple virtual device testing in one workflow (see: https://devcenter.bitrise.io/testing/device-testing-for-android/ ).

I fixed this in our project by adding separate workflows for each module that i want to test.
