### User Story
As a < developer >, I want < a separate test database > so that < tests do not affect the dev database >.

### Description
At the moment the test and development database are one and the same.
I find it unconvenient and would like to improve the situation.

### Definition of Done
Tests are running on their own database, separate from the dev one.
