I've just about got it working. cypress runs and can see the baseUrl I tell it to go to, but it can't access the actual localhost:3000 server, says it isn't running. I tried npm start on both windows and wsl2 ubuntu to no avail, now what I'm doing is setting the

--entrypoint=""

running

/bin/bash

, running

npm start

, then opening another terminal and running

docker exec -it container_id cypress run

at the same time. that seems to work, but ONLY if i copy the spec files from cypress/e2e to cypress/integration, which is odd, as the latter is a legacy folder, I believe. if I don't do the last step, cypress complains that

cypress/integration

is empty!
