Playwright
Microsoft's open-source framework for end-to-end browser tests.
Best for End-to-end tests of a web app
Playwright is Microsoft's open-source framework for automating Chromium, Firefox, and WebKit. You write tests that click through the real app. It is the default here for end-to-end coverage of a vibe-coded web app, because it is free and it tests what users actually load.
Best use cases
- Clicking through signup and checkout
- Catching a broken deploy before users do
- Generating tests while an agent watches the browser
Pros
- + Open source and free
- + One API for the three major browser engines
- + Traces and screenshots make failures readable
Cons
- − End-to-end tests are slower and flakier than unit tests if you write them carelessly
- − You have to run them somewhere. CI minutes are not free
Pricing
Open source and free.
