Rubocop

I get my system test working at the start of video but the problem is it works so well that it still passes even after I re-introduce the bug when it should have failed. Crap! That means my test is not working correctly.

I spend the rest of the video trying to figure out why the test is not failing when it should and get very frustrated. So frustrated this became my longest video yet at over two hours! End up digging into the RuboCop code to try and figure out what is going on. I do figure out the problem at the end of the video in a ah-ha moment. Spoiler: the problem was I didn’t link to the Standard config file correctly.

The older I get the more I appreciate code linters. Something that can detect and often correct my formatting errors? Great! One less thing I have to worry about. Then I can spend my time on more important tasks such fixing the bug, adding a new feature, or uniting/conquering the world.

The default linter for Ruby is Rubocop. It works great but I find it’s default rules to restrictive. You can change the defaults but that is time consuming and confusing. At least confusing to me. While searching for a Rubocop config that I liked I came across Standard.
