# This flag enables your test to run using Device Farm's Amazon Linux 2 test host when scheduled on
# Android devices. By default, iOS device tests will always run on Device Farm's macOS test hosts.
# For Android, you can explicitly select your test host to use our Amazon Linux 2 infrastructure.
# For more information, please see:
# https://docs.aws.amazon.com/devicefarm/latest/developerguide/amazon-linux-2.html

# Phases represent collections of commands that are executed during your test run on the test host.
phases:

  # The install phase contains commands for installing dependencies to run your tests.
  # For your convenience, certain dependencies are preinstalled on the test host. 

  # For Android tests running on the Amazon Linux 2 test host, many software libraries are available
  # from the test host using the devicefarm-cli tool. To learn more, please see:
  # https://docs.aws.amazon.com/devicefarm/latest/developerguide/amazon-linux-2-devicefarm-cli.html

  # For iOS tests, you can use the Node.JS tools nvm, npm, and avm to setup your environment. By
  # default, Node.js versions 16.20.2 and 14.19.3 are available on the test host.
