Hey all, we are planning to implement a GitHub app. Can't figure out how to setup a testing environment. Any ideas?

Not from experience yet, but i assume doing it private first and following thier guide ? https://docs.github.com/ja/enterprise-cloud@latest/apps/publishing-apps-to-github-ma[…]using-the-github-marketplace-api-in-your-app/testing-your-app

Take a look at this, this contains step by Step implementation guidelines on how to place ur app and perform a CI https://docs.github.com/en/apps/creating-github-apps/guides/creating-ci-tests-with-the-checks-api
