This is very good to read!!
Please consider adding some information on when it is recommended to use @Import or @JmixModule (see here), @ContextConfiguration, … there are a lot of options and there’s very little information on their differences when applied to Jmix projects.
Wether there is / will be some @DataJpaTest equivalent, Mainly an annotation for tests that do not rely on UI and ones that do.
Wether @SpringBootTest is the way, or if other more lightweight options apply for unit tests.
That will save us lots of “let’s try this and see if it works” !
