Suite-Scheduler README

Developer Setup


suite-scheduler is an AppEngine Standard Python Environment V1 application. You need the Google Cloud SDK's AppEngine Python component to develop and deploy this application:

  • Install Google Cloud SDK:
    • Follow the instructions to install the Python App Engine component.
  • Log in to gcloud: gcloud auth login <username>
  • Install App Engine Python extensions
    • ./install_gcp_reqs

Developer environment

Suite-scheduler development must be done in the standard Chrome OS source checkout but entirely outside the Chrome OS chroot environment.

suite-scheduler uses depot_tools/vpython to provide a stable environment for development and release.

First, make sure you have depot_tools installed and stored within your $PATH

Then, to (re)initialize developer environment, run


For testing changes beyond to the configs/ directory, and for deploying suite-scheduler, you must also obtain certain service credentials used by suite-scheduler.

  bin/setup_environment --load-creds

If you get failures when trying to download credentials,

  • Double check you're logged into the Google Cloud SDK by running gcloud auth list.
  • Contact Test Platform team or one of the OWNERS to be allowlisted.

Testing your changes

Changes must be validated with the full test suite:

  bin/run_tests --debug  # More verbose

These tests include some integration tests that can take over 5 minutes to run.

** WARNING: suite-scheduler unittests do not currently run in presubmit. You MUST ensure that unit-tests pass locally for your change. **
