How to specify a specific junit test to run

what is the gradle syntax for running a specific junit test (or suite for that manner) - the mantle-usl AccountingActivities test, for example. I know it has something to colon separated paths, but I cannot find an example

Ha! found it in my own notes:

./gradlew :runtime:component:agenda:test --tests “StoreAgendaFacadeServiceTest”

Actually when I run that line, I get:

Project ‘agenda’ not found in project ‘:runtime:component’

If i use ‘mantle-usl’ instead of ‘agenda’ it works. What do I need to do to make gradle think ‘agenda’ is a project? I would have guessed the ‘component.xml’ file by setting it to ‘agenda’ didn’t work.

It is having a ‘build.gradle’ file in the component’s directory
