[FR] ADD MORE TESTING!

[reactiveclown]

Is your feature request related to a problem? Please describe. As the name suggests we need more testing. Right now there is only one class with tests for a single request.

Describe the solution you'd like As the name suggests, add more tests :)

Describe alternatives you've considered No alternatives, just add more tests.

Additional context I still do not know, would that be enought if I'll only add a unit tests. Maybe also the integration tests should be added.
