GitHub Copilot and ChatGPT are strictly prohibited on this repository.

For Anime/Manga list tests Sakura-sou no Pet na Kanojo (Anime#13759 and Manga#28107) will be used.

The test cases will create a backup of your list in the anime-list.txt and manga-list.txt files. Make sure you fix your ratings and any other information that might be overwritten by this test.

Ignore test failures for these known issues: ⚠️ External Issues.

For local tests you can use Java 8+, however only methods in the Java 8 API may be used. The src/main/java9 and src/main/java11 folders should not be marked as a source root.

Run tests locally by adding a text file named client.txt that contains the client ID in the src/test/java/resources directory.

Please note that the client ID being used for tests must not have a client secret and must have an app redirect url of http://localhost:5050.

Tests can be run using GitHub Actions by running the MyAnimeList CI workflow manually in the actions tab of your fork. Note that this requires two secrets, a MAL_CLIENT which contains the client ID, and a MAL_TOKEN which contains the OAuth token (ex: Bearer <oauth token>).
