Amazing! Glad my work was a useful starting point, but it sounds like you’ve made it a lot better!
I like the system you have for keeping all the travis stuff in a separate repo, rather than having to copy the .travis.yml file around. It would be nice to have an ‘official’ version of this for plugin developers to use (and for us to use in core plugins).
Cool! I had no idea you could control the folding just by echoing a string! A pull request to add this would be welcome, as long as it is behind an ENV variable.
This is interesting, I think it’s probably worth starting a new topic to discuss any core changes that would be useful for coverage reporting.
