Add GitHub Action to run tests

Changes

Added tests.yml:

• This file sets up GitHub Actions to automatically run tests whenever a Pull Request is opened, synchronized or there is a push to branches main and develop.

How to test

1. After this Pull Request has been opened, check if:
   • GitHub Actions run as expected and all test cases succeed;
2. Make a minor change to the code and commit. Verify that:
   • The actions run once again and all test cases succeed (except if the change made is a breaking change);
