Running tests for Android app takes > 10 mint vs 1-2 mints locally, how to speed up?

[Abdallah Abd El Fattah]

Hello,

I've been trying to use bitbucket pipelines to run unit tests in our Android app, but it seems to take way longer than it does locally!

Running locally takes 1 - 2 mints, but running the pipeline takes more than 10 mints!

I'm kinda new to this, so I'm not sure what might need to be cached for example.

Troubleshooting steps:

• I tried to cache the following,

  - maven
  - gradle
  - gradlewrapper

  but diving in the logs it says the following:
  

  Cache "maven": Downloading
  Cache "maven": Not found
  Cache "gradle": Downloading
  Cache "gradle": Downloaded 175.7 MiB in 4 seconds
  Cache "gradle": Extracting
  Cache "gradle": Extracted in 1 seconds
  Cache "gradlewrapper": Downloading
  Cache "gradlewrapper": Downloaded 250.8 MiB in 3 seconds
  Cache "gradlewrapper": Extracting
  Cache "gradlewrapper": Extracted in 2 seconds

  So it doesn't seem like it was able to find maven, and I'm not sure if it found gradle or gradlewrapper as it says that it downloaded it anyway, am I understanding this incorrectly?

• Also, going throw the logs, I can find that it downloads lots of 3rd party dependancy each time, ex stuff related to Google, Kotlin and JCenter.. I think that it might be better to cache those as well, but to be honest I don't know how to do so yet.

            - androidavd
          script:
            - echo "Start testing"
            - bash ./gradlew test -i
            - echo "done testing!"

definitions:
  caches:
    gradlewrapper: ~/.gradle/wrapper
    androidavd: $ANDROID_HOME/.android/avd

What should I do?

Any ideas, pointers, thoughts are welcome. :)
