Playwright & Vitest
Robots that click through your app and check the maths, so you don't have to re-test by hand.
1. Learn it
- Vitest checks small pieces: given this input, expect that output.
- Playwright drives a real browser: fill the form, click submit, expect the page to say thanks.
- One test of the flow that earns you money is worth fifty tests of buttons.
- Tests are how you change code without holding your breath.
Cost: Free.
2. Practice it
Simulated — nothing real happensName the one test
If you could only test one path in a paid AI app, which is it?
3. Connect it
Real — your own account- 1Add Playwright to your project and record one flow.
MessyDev never signs you up, spends your money, or touches your accounts. You do that part.
4. Use it
Once other people rely on the thing not breaking.
Honest alternatives
There is no single correct stack. Any of these would be a reasonable choice instead.
