+## Motivation
 
 The motivation behind this library is to provide a setup such that application developers don't feel the need to disable security in their apps when running tests! If you have any issues with regards to OAuth2 and tokens et. al. and consider to disable "security" when running tests please submit an issue or a PR so that we can all help developers and security to live in harmony once again (if ever..)!
