It all seems to work pretty well. How do you think we should consume the coverage reports @paudmir? We can generate the report in CI and make it available on any PR. We could go even farther and have CI fail if a PR causes coverage to drop. A middle ground would be to just track coverage for a while and make it easy to see the effect of a given PR on coverage. Looks like we can probably use https://about.codecov.io/ for free because the repo is public. I'll try it. |

@david-crespo I think tracking it for a while would be good, and add tests to cover what is missing, which I think will mostly be making things fail on purpose😄 |

I tried to clean the mess I have while I was testing different things, so I can't guarantee that this is going to work right away yet it's on the right path 😄
I did install these packages:
npm install v8-to-istanbul npm install babel-plugin-Istanbul npm install monocartI have a hunch that the monocart one might not be necessary to run what is out there.
With these, one just needs to run the playwright tests as usual (just gotta point the
testmodule to the one in thefixtures.tsso that the code coverage can run).e.g. npm run e2ec -- action-menu
This should generate a
.nyc_outputfolder with non-emptycoverage.jsonfile.To generate the HTML so you can see the report, you'll need to run this command:
npx nyc report --reporter=htmlA report would look like this:
PS. THIS IS JUST AN EXAMPLE/guide, so not intended to be deployed @david-crespo
