Test reporter for multi-project sbt

I have a build.sbt with about two dozens of project having hundreds of test. I would like a test reporter that can aggregate tests from all projects in build.sbt into a single table, so I don't have to look into every project to see test results.

Any solution, either a custom test listener or junit-style xml-file aggregation would work for me.

I would the reporter do both:

• display a list of tests with statuses in the console output of sbt test and
• have the same report in a single file.

The main goal it to have a single report for all projects in build.sbt.

Thank you
