Goal: Make sure users can sign up, log in and complete a purchase without errors on desktop and mobile.
What I did:
- Wrote a test plan and 12 test cases for login, cart and checkout
- Ran manual functional, UI and cross-browser testing
- Built automated regression suites (30 tests) for the key user flows
- Logged 6 bugs with severity, steps to reproduce, screenshots and recordings
Result: Found a critical checkout bug on Android Chrome that would have blocked customers from placing orders.
