The files in this directory serve as plumbing for running tests under Kokoro, our internal CI tool. If there are any changes required to these config files, please file an issue.

The build script runs each time a PR is opened, or when a commit is pushed to an open PR, or when an a PR is merged into the master branch. The script runs on a Google Compute Engine machine hosted in our own Google Cloud project, with public access to the logs.

The script downloads the dependencies it needs, compiles, builds, and unit tests the code, and then uses Firebase Test Lab to run instrumentation tests. Code coverage reports are then uploaded to Codecov, where they are displayed on the GitHub Pull Request/Repo Homepage.

WARNING:Do NOT run the script on your local machine.
