Find the Commit that Broke the Tests with `git rebase –exec`

Nice tip by Kamran Ahmed:

Find the commit that broke the tests

$ git rebase -i –exec "yarn test" d294ae9

This will run "yarn test" on all the commits between d294ae9 and HEAD and stop on the commit where the tests fail

If you want to go back X commits use a regular HEAD~X:

git rebase HEAD~3 --exec "yarn test"
