Thank you Jan, really useful to get updated on the challenges on community packages.
meteor-mocha & meteor-mocha-core
The Mocha packages are part of Meteor Testing. Both packages will get releases during Hacktoberfest in preparation for Meteor 3.0 release. In the meantime you can help with fixing bugs and for example working on better integration with VS Code.
As mentioned here, I already expeirmented with test packages for Meteor 3.0 by removing the fibers. I am not sure if I should proceed there with a PR since I don’t know if those changes are already covered or assigned. The post you wrote reflect that it will get releases and I assume someone is in charge since you ask help for other issues.
My change is a minor change to remove a single point using fibers and have compatibility with latest Meteor versions.
Regarding meteor-browser-tests, I use it on my projects but I had to adapt a bit the driver I use “puppeteer”. However, I saw the issue you mentioned and found the github issue of having problems with chromedriver too and surely it happens through all drivers since newer selenium 4,x changed the API and produces breaking changes. I will be reviewing them as I have time to dedicate to OS,
The initial PR for this:
