Acceptance test are compose of New feature and regression test (existing feature), e.g. most of the April release is regression
The user manual is updated at each release not yet done for April as communicated (done after the release) details on the different documentation will help to understand what was meant.
The system/integration test should be launch at each Pull Request by travis-ci
in the QA platform, we can create a bug linked to the test case meaning we have the way to repeat
the system test ARE part of the code repo
Travis has changed pricing model - free version no longer available, free minutes for OS projects can be requested, but have to be refreshed regularly
