Faster and better integration tests with Drupal Test Traits

Using drupal-test-traits https://gitlab.com/weitzman/drupal-test-traits you can run tests in an existing Drupal site, with all necessary configurations installed. This leads to better integration tests. Unlike default Drupal test framework, you only install all the config once, and this leads to faster integration tests.

I have used that test framework in a project at Axelerant. I would like to share the knowledge and experience in the session.
