Shared libraries

Git-Mastery maintains reusable libraries that support exercise verification and testing.

These libraries are most relevant when you are working on reusable grading behavior rather than a single exercise.

Main libraries

• repo-smith: repository construction for unit tests
• git-autograder: grading helpers and verification abstractions

When to use which library

• Reach for repo-smith when your test needs a specific repository history or working tree state.
• Reach for git-autograder when multiple exercises would benefit from the same verification helper or abstraction.

Scope of this section

This section focuses on the shared libraries that Git-Mastery contributors are most likely to touch while working on verification behavior or test infrastructure.
