/**
 * NOTE: The firebase emulator must be running for the test to work. I recomend putting you rules test in a different folder
 * from the rest of your code and use `vitest --dir path-to-test-dir` to seperate them.
 * you can use the `firebase emulators:exec --only firestore` to create a firestore instance before running the tests and 
 * it will also shut down automatically,
