Creating a Dummy Apple ID for App Testing: Best Practices and Developer Strategies

Hello everyone! I have a question (issue). I need to write a test for an app, and everything is okay with my tests, but I need to test login with an Apple ID, and I don't want to use my private Apple ID because I plan to post this test on GitHub. Is there any possibility to create, for example, a dummy Apple ID account? Or how do developers typically handle this situation?
