If we wanted e2e tests / CI, here's the steps as I see it:

• Add some basic unit tests (jest) and run those first in the CI build
• Pull the server repo
• Set up a Mysql instance
• create a npm run resetdb method to reset the database with the test data before each test
• Use the mock version of Google Places API and make sure all test-run queries are prepared
• build and start the PHP Lumen API in "testing" mode with CI .env config
• Run cypress tests

Still leaves open the question of how to handle the email / confirmation step for posting a score / grade. Possibly tail the PHP logfile for the emailed link (since the tests use the "log" email driver and write the emails to the log, rather than sending).
