I recently discovered a handy feature of rails system specs I wanted to share. This only works if you’re using the iTerm terminal on Mac. Generate a new system test: rails generate system_test example Make sure the generated system test fails, for example by adding a the following: assert_selector "h2", text: "I should fail!" Run the test with the RAILS_SYSTEM_TESTING_SCREENSHOT ENV variable set to inline: RAILS_SYSTEM_TESTING_SCREENSHOT=inline rails test:system The failing test triggers a screenshot and renders it directly in the terminal, making it easy to debug the failure visually....
