guess it's slightly OT, but which testing framework do people use for their javascript side of their cfml apps?

I've no experience with it myself, but I've heard Jest is decent.

We use either Mocha & Chai or Jest, but Jest is the more up to date version

I've done only proof-of-concept / spike front-end testing, and swerved Jest as it seemed clumsy to me. I've used Mocha and Chai and liked them, and had a quick peek at Puppeteer (all documented here: https://blog.adamcameron.me/2021/01/part-8-testing-simple-web-page-built.html). In talking to QA automation bods recently, they are falling on the side of cypress.io though, as it's a bit more usable than Puppeteer, and is all zeitgeisty, apparently.

we use https://github.com/codeceptjs/CodeceptJS for our QA automation, it's ok, just takes a while to run. once I suggested moving to using selectors rather than waiting for text, we got less errors as copy got updated

agree with Adam on Jest, too clunky Cypress previously, now playwright

+1 for Playwright. I tried Cypress and had issues which there were open issues for but Cypress devs didn't seem very responsive even though there were a lot of people with the same issue... I then tried CodeceptJS which was nice but it's just a layer on top of another framework which is supposed to allow you to switch frameworks - but I didn't really see the benefit of that so just moved to Playwright itself. So far very happy with Playwright, great docs, good support, frequent updates and it's very fast...

This is clearly impossible!

@joechastain LOL - oh yeah I forgot to mention ... it's made by Microsoft (gasp) :)
