📝 Walkthrough

Walkthrough

Adds a test:watch script (jest --watch) to package.json and appends two new subsections to README.md documenting the npm run test:watch and npm run test:coverage commands for Jest usage.

Changes

Jest Watch Mode Script and Docs

Layer / File(s)	Summary
test:watch script and README documentation package.json, README.md	Adds test:watch (jest --watch) to package.json scripts; appends "Watch Mode" and "Coverage Reporting" subsections to README.md with the corresponding npm run commands.

⚠️ Note: README.md documents npm run test:coverage, but package.json removes the test:coverage script rather than retaining it alongside the new test:watch entry. The linked issue explicitly requested both scripts to coexist.

Poem

🐇 Hop hop, a watcher appears,
No more rerunning tests to calm my fears!
jest --watch now lives in the script,
But coverage docs and code got a rift —
One command's documented, yet nowhere defined,
A mismatch a careful bunny would find! 🔍
