AI Test Generator (Pre-commit)

This project includes a pre-commit workflow that uses Codex to generate or update tests for the current git changes, then runs only those managed tests before allowing a commit.

What it does

• Builds or refreshes test-memory.json from package.json to capture framework, versions, and test setup.
• Sends the current git diff and test-memory.json to Codex for test generation or updates.
• Tracks all test files written by the hook in test-memory.json and runs only those files.
• Stages generated tests and test-memory.json automatically.
• Blocks the commit if Codex fails or managed tests fail.

How it works

1. Read package.json to detect framework, language, and test setup.
2. Load or create test-memory.json.
3. Build the git diff (staged + unstaged).
4. Run codex exec with the diff and memory.
5. Register any changed tests in test-memory.json.
6. Run npm test -- --watchAll=false --runTestsByPath <managed_files>.
7. Allow the commit only if tests pass.

Files

The workflow generates and maintains internal metadata and logs as part of the pre-commit process.
