Ejemplo: archivo de especificaciones de prueba de Device Farm que muestra un host de prueba de Android

El siguiente fragmento es un ejemplo de un archivo de especificaciones de prueba de Device Farm que configura una ejecución de prueba de NodeJS de Appium con el host de pruebas Amazon Linux 2 para Android:

version: 0.1

# This flag enables your test to run using Device Farm's Amazon Linux 2 test host. For more information,
# please see https://docs.aws.amazon.com/devicefarm/latest/developerguide/amazon-linux-2.html
android_test_host: amazon_linux_2

# 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. To lean about which
  # software is included with the host, and how to install additional software, please see:
  # https://docs.aws.amazon.com/devicefarm/latest/developerguide/amazon-linux-2-supported-software.html

  # Many software libraries you may need are available from the test host using the devicefarm-cli tool.
  # To learn more about what software is available from it and how to use it, please see:
  # https://docs.aws.amazon.com/devicefarm/latest/developerguide/amazon-linux-2-devicefarm-cli.html

  install:
    commands:
      # The Appium server is written using Node.js. In order to run your desired version of Appium,
      # you first need to set up a Node.js environment that is compatible with your version of Appium.
      - devicefarm-cli use node 18
      - node --version

      # Use the devicefarm-cli to select a preinstalled major version of Appium.
      - devicefarm-cli use appium 2
      - appium --version

      # The Device Farm service automatically updates the preinstalled Appium versions over time to
      # incorporate the latest minor and patch versions for each major version. If you wish to
      # select a specific version of Appium, you can use NPM to install it.
      # - npm install -g appium@2.1.3

      # For Appium version 2, Device Farm automatically updates the preinstalled UIAutomator2 driver
      # over time to incorporate the latest minor and patch versions for its major version 2. If you
      # want to install a specific version of the driver, you can use the Appium extension CLI to
      # uninstall the existing UIAutomator2 driver and install your desired version:
      # - appium driver uninstall uiautomator2
      # - appium driver install uiautomator2@2.34.0

      # We recommend setting the Appium server's base path explicitly for accepting commands.
      - export APPIUM_BASE_PATH=/wd/hub

      # Install the NodeJS dependencies.
      - cd $DEVICEFARM_TEST_PACKAGE_PATH
      # First, install dependencies which were packaged with the test package using npm-bundle.
      - npm install *.tgz
      # Then, optionally, install any additional dependencies using npm install.
      # If you do run these commands, we strongly recommend that you include your package-lock.json
      # file with your test package so that the dependencies installed on Device Farm match
      # the dependencies you've installed locally.
      # - cd node_modules/*
      # - npm install

  # The pre-test phase contains commands for setting up your test environment.
  pre_test:
    commands:

      # Appium downloads Chromedriver using a feature that is considered insecure for multitenant
      # environments. This is not a problem for Device Farm because each test host is allocated
      # exclusively for one customer, then terminated entirely. For more information, please see
      # https://github.com/appium/appium/blob/master/packages/appium/docs/en/guides/security.md

      # We recommend starting the Appium server process in the background using the command below.
      # The Appium server log will be written to the $DEVICEFARM_LOG_DIR directory.
      # The environment variables passed as capabilities to the server will be automatically assigned
      # during your test run based on your test's specific device.
      # For more information about which environment variables are set and how they're set, please see
      # https://docs.aws.amazon.com/devicefarm/latest/developerguide/custom-test-environment-variables.html
