qaaas-test-app

A deliberately buggy todo app for testing QAaaS.dev and PRaaS (Pull Requests as a Service).

Quick start

npm install
npm start
# open http://localhost:3111

Known bugs (for QA agent to find)

This app has 8 intentional bugs that the QAaaS browser agent should detect and PRaaS should generate fixes for:

#	Bug	Location	What happens
1	Empty todo submission	server.js POST /api/todos	No validation — submitting an empty title creates a blank todo
2	ID type inconsistency	server.js POST /api/todos	ID stored as number but compared as string in some routes
3	Toggle completion broken	server.js PATCH /api/todos/:id/toggle	Strict === compares string param to number id — always 404
4	Update overwrites todo	server.js PUT /api/todos/:id	Replaces entire object instead of merging — loses completed/priority/createdAt
5	NaN completion rate	server.js GET /api/stats	Division by zero when no todos exist — returns NaN
6	Broken About link	public/index.html nav	Links to /about which has no route — serves index.html as fallback
7	NaN% displayed	public/index.html stats	Shows "NaN%" in the UI when stats endpoint returns NaN
8	No plural for counter	public/index.html counter	Always says "X item left" even when X != 1
