Clean code principles dictate that we reuse these fixtures across tests and make them as abstract as possible. For example, if two tests require speaking to a database, then it would be obvious to reuse the same database connection code for both. It is important to try and avoid duplicating the fixture code across those tests. The more code duplication you have in your tests, the greater drag the tests will have on refactoring the actual.

- Refactor using Scala
- Override
