Gwen can generete JSON reports enabling you to feed evaulation results into other Gherkin report formatters or your own custom one.

Generate reports​

Launch Gwen with the -f json option to generate JSON reports when executing your features.

Example

Execute features in the gwen/features/todo folder and generate JSON reports only.

yarn gwen -b -f json gwen/features/todo

Execute features in the gwen/features/todo folder and generate HTML and JSON reports.

yarn gwen -b -f html,json gwen/features/todo

Gwen Launcher

Output​

  • Reports will be generated in the gwen/output/reports directory as per the default gwen.launch.options.report setting
    • The JSON report files will be generated at gwen/output/reports/json/*.json.
    • The HTML report will be generated at gwen/output/reports/index.html.
    • If you want reports generated in a different directory, you can either:
      • Amend the above setting to change the default
      • Or include the -r|--report CLI option and specify a directory on every launch
