Humanitec implemented social authentication with GitHub on their Internal Developer Platform (IDP) to provide users with a one-click experience, making it easier for them to access the application. Social authentication offers several benefits, including increasing registrations, making authentication easier, and automating email verification. The implementation faced challenges, such as parallel test runs using the same user, security verifications, and controlling the state of GitHub users and organizations. To overcome these challenges, Humanitec used test automation to continuously verify the implementation of social authentication. Test automation allows developers to run multiple tests per day without human error, providing fast and concise feedback, which is essential for supporting developers in a rapidly changing environment.
