Ruby metric reports for Jenkins. Rcov, Rails stats, Rails notes and Flog.

Rcov support

Rcov plugin parses rcov html report files and shows it in Jenkins with a trend graph.

If the build was successfuly, Jenkins generates the trend report and the graph:




Rails stats support

Once the plugin is installed we can publish rails stats reports checking the right option:

 Jenkins generates a report by each successful build and keeps an historic version while the project goes forward:


Rails notes support

Flog support

Flog measures code complexity. It shows you the most torturous code you wrote.

Check the right option in your job's configuration and add the directories that you want to monitorize, i.e app/models
