@jburel : if you plan to go back through all the travis files, does adding -i (or some form of verbosity) make sense so that we can see what tests were run? (a la ome/omero-gateway-java#1 (review))

[jburel]

We discussed that with @dominikl last week I am a bit worried that it is too verbose
If people think it is useful then yes

[joshmoore]

Yeah, I know the feeling. An alternative might be to update one of the plugins to print a single line per test.

Edit: not that we need anything this elaborate, but https://github.com/radarsh/gradle-test-logger-plugin looks nice. I've failed though to activate it via -I init.gradle due to gradle/gradle#1322 cc: @manics )

[jburel]

This will require a bit of investigation. Something for another round of work
