[Pharo-dev] Which tests should be run in CI?

I notice that several builds are green, though I added a breaking test to Pharo 3. That probably means that those builds don't run all of the Pharo tests. Most builds probably don't need to run all tests (all the time), but it might be useful to be able to mark tests as integration tests, that are expected to be run by all downstream builds. Concrete, every Pharo 3 build that loads Grease should currently be red. Stephan
