 - All individual unit tests are independent of each other. We don't use any shared state between tests.
 - Test environment includes `sakila` sample database and any change to it by a test is reverted before running other tests.
 - While running unit tests, it tries to connect to mysql server running on `localhost:3306` with username `root` and password `password`(which can be configured) and if not found, it will use `sqlite` as a fallback, hence no requirement of any sql server to run tests.
