@esteve Sorry we never got a chance to look at this. Since I was passing through this repository, I took the opportunity to rebase it, clean it up, and get all combinations of the tests working using the newer CMake infrastructure. Hope you don't mind. Have a look and let me know what you think.

Note: Do you think we could we extend the current publisher / subscriber and test_publisher_subscriber templates rather than adding another set of talker and listener scripts? This would also allow testing different message types and custom node names / topic names that have proven to cause flaky tests when nodes from the previous tests haven't finished shutting down properly

Hm, yeah, that's a good point. It is probably possible; let me take a quick look and see how hard it will be.

marking this as connecting to #214 and removing question label

[jacobperron]

I'm going to close this due to its age and inactivity. We still have the open issue if someone wants to revisit testing QoS combinations: #214
