I'm not sure if I understand your question. This codec operates on raw Git objects. The test fixtures contain objects of the types blob, commit, tag and tree, which seem to be all types that Git supports.

What are you missing? Can you give examples of such Git objects?

tree only record file list
tag is just tag info
commit didn't has file info

so where is file change record ( rename , delete, add, edit )?

AFAIK, those things are not stored in Git, they are calculated. For more information about renames, https://chelseatroy.com/2020/05/09/question-how-does-git-detect-renames/ is a good read. And for Git internals I recommend the "Git Internals" chapter from the Git book
