How it started

• Cucumber JSON, hurray!
• I really like Maven

–Me to myself
„Just because you have all the data,
you don’t have to show all the data.“

What is Cluecumber?
• Java library or Maven plugin for Cucumber
JSON reporting
• Focus on clear and concise information for
testers
• First open-source release in November
2017

12. softwaretester.blog | Benjamin Bischoff
Why JSON and not messages?
• It is easy to parse
• It is ready at the end of a run
• Works with other frameworks

13. softwaretester.blog | Benjamin Bischoff
What’s inside?
Parse, aggregate and
pre-process
Cucumber JSON files
