Ranked in these QuestionsQuestion Ranking
Pro Works great with modern node.js features
Pro Runs a real browser
Unlike the other options here, this is a real browser, just without the GUI parts. This means the quality of the test is much higher, and lets you do things like save to PDF or images.
Pro Actively developed and promoted by Google
Pro Complete API for Chromium included
Chromium tests depend on the same API that Puppeteer gives you access to, so all the features are included
Con Not good for Cross Browser Tests
Since it only tests via Chromium, it won't help you test inconsistencies between browsers like Edge or Safari. There are projects to get around this, but they aren't mature.
