Feature: Rerun formatter The rerun formatter writes an output that's perfect for passing to Cucumber when you want to rerun only the scenarios that have failed. You can save off the rerun output to a file by using it like this: `cucumber -f rerun --out .cucumber.rerun` Now you can pass that file's content to Cucumber to tell it which scenarios to run: `cucumber \`cat .cucumber.rerun\`` This is useful when debugging in a large suite of features.
