- In a configuration file
{ failFast: true } - On the CLI
$ cucumber-js --fail-fast
By default, Cucumber runs the entire suite and reports all the failures. failFast allows a developer workflow where you work on one failure at a time. Combining this feature with rerun files allows you to work through all failures in an efficient manner.
A note on using in conjunction with Retry: we consider a test case to have failed if it exhausts retries and still fails, but passed if it passes on a retry having failed previous attempts, so failFast does still allow retries to happen.
