Testing commands
Test PRs
Make sure you are in the base branch of the PR (mostly develop). You also aren't allowed to have any not checked in changes.
Then run:
git fetch origin pull/<PRnumber>/head && git checkout FETCH_HEAD
This only works for PRs which don't depend on another PR which hasn't been applied up to now. For the other case you either need to locally merge the PRs in a temporary one or merge them in a fork on Github.
When you are done with testing the PR just run this to get back to the develop branch:
git switch develop
