Help running tests in a browser in GitHub Actions

[ericoporto]

Hey, I have a wasm/js/HTML thing built. I would like to run it on a browser in GitHub Actions CI and print the console.log output to the CI log and if possible also grab a file that is generated in the MEMFS/IDBFS.

Any ideas on this are welcome. Asking here because I imagine more people have the need to test their code in CI pipelines that are also here.

In general you can run browsers in headless mode on CI. Here is where Emscripten itself does that:

emscripten/.circleci/config.yml

Line 311 in ecdca7b

CHROME_FLAGS_HEADLESS: "--headless=new --remote-debugging-port=1234"

Note the use of "new" headless mode in Chrome there, which works better in our experience.

Running with emrun should log out stdout/stderr to the console. I don't think it captures console.log as well but that should be easy to hook up too.

Nice, that is really useful information! Thank you!!

You can also use the selenium webdriver to drive your tests. Googling "selenium github actions" gives a bunch of resuts.
