Farmer

A web client built to interact with AWS Device Farm's remote access API.

The client was designed to be imported as a dependency in beak to interact directly with our devices on Device Farm.

Local development

• Clone this repo locally
• Run npm install
• Run npm run start to start a webpack dev server build, this should automatically open a browser tab at http://localhost:8080/ with example/index.html as content
• In Rainforest repo run bundle exec rails console to open rails console
• first create a device farm client:

device_farm = Aws::DeviceFarm::Client.new(region: 'us-west-2', credentials: Aws::Credentials.new(GetEnv['DEVICE_FARM_PUBLIC_KEY'], GetEnv['DEVICE_FARM_SECRET_KEY']))

• Get a project arn by running device_farm.list_projects
• Get a device arn from https://admin.rainforestqa.com/devices
• Create a remote session on device farm:

remote = device_farm.create_remote_access_session({
  project_arn: PROJECT_ARN,
  device_arn: DEVICE_ARN,
  name: "Remote Session Test",
  configuration: {
    billing_method: "METERED",
  },
})

• to get our websocket session endpoint keep on running the following until endpoint is not nil (status should be RUNNING). It will take ± 2min for the remote session to provision and this to return an endpoint.

access = device_farm.get_remote_access_session({arn: remote.remote_access_session.arn})

• Get the endpoint value

access["remote_access_session"]["endpoint"]

• Open the tab with http://localhost:8080/

• Paste the endpoint value into the input form at the top

• Set the right device dimensions into the form fields, this is important for click events to end up on the right places, the dimensions are stored in the remote_access_session attributes

• Click 'Launch Farmer' button

• Profit!

• Remember to close the remote session after you're done testing

device_farm.stop_remote_access_session({arn: remote.remote_access_session.arn})

Deployment

A new version of the package has to be published to NPM. Depending projects have to update their package.json to use the latest version.

Publishing a new version to NPM is automated via CircleCI workflows that kick off when changes with a new package.json version are merged to the master branch.
