* Add api test (#173)

* Add unit tests for api
only added two tests, many cases are covert by frontend

* Modify tests/api_tests/test_api.py
add assert

* Add an other test
add test_wrong_body

* Remove print statements

* Remove __pycache__/test_api.cpython-311-pytest-8.3.2.pyc

* Add variables for expected values

* Update api test to new requirements

* Add test_getenphse_authorization_url.py

* Add test_getenphse_token_and_system_id
- bad redirect url
- bad redirect url with correct param
- fixtures

* Update requirements.txt
