Looks awesome! Love the Github Actions automation :D

Did you consider Cypress? Personally, I prefer Cypress over Puppeteer for E2E tests, mainly because it has a really great development experience and also has handy tools like outputting screen recordings for debugging.

I think you can achieve all the same stuff in Puppeteer but it is just a little more effort.

I didn't know of Cypress- seems to have few advantages, so I can swap it out if others prefer. I haven't used either extensively, but I do know Puppeteer takes screen shots (but perhaps not recordings?).

Only one test written so far using Puppeteer (launch Dasher, take screenshot) so before writing others, now would be good to decide

Yeah definitely good to decide before we start writing lots of tests.

My vote would be Cypress. Its worth noting that there is also a paid for service (thats free for OSS) you can use with Cypress that allows you to view your test runs in a nice UI, although its by no means required and can be added later if we end up with a huge suite of tests. You can still export videos as an artifact from actions without it. Its also worth noting that cypress has a prebuilt github action, to make running it slightly simpler.

Shameless plug, you can see an example of all this in action on the AceCentre website repo 😉

Updated to use Cypress- Testing Check passes- currently failing ESLint rules (in a future PR).

Does it run the tests on every commit or only on commit to main?

[jcope]

Tests can be run locally, but the actions are setup to run on every push. So if the commit is pushed to Git, then it will trigger a run.
