Hi @Jean85 , I noticed in some of the previous issues opened there was a request for this and based on the discussion there and based on my personal project requirements I implemented the --print-failed-early option in the MR accompanied with this issue and on my rewrite of paraunit.

Note: I implemented the same for version 2.x but I noticed you have not exposed the TestResut class there and you are only referencing the outcome TestOutcome | TestIssue and those do not have access to the Failures -> message printer but I will look into some options how that can be achieved there as well.
