By default, if the current branch tip exists on remote origin,
the current branch is compared against its tip on GitHub.
Otherwise it's compared against 'develop'.
This script runs the following tests in all cases.
- Javascript and Python Linting
- Backend Python tests
Only when frontend files are changed will it run Frontend Karma unit tests.
If any of these tests result in errors, this script will terminate.
Note: The test scripts are arranged in increasing order of time taken. This
enables a broken build to be detected as quickly as possible.
