thanks for that ... this way I deffiitely can get a better feeling for the

I know hamcrest for quite some time as the original author of the flexmojos
plugin liked hamcrest too.
Haven't used it that much in the past though.

Personally, I find the AssertJ (and practically all other attempts at this)
less powerful and harder to work with, as the DSL is not necessarily
intuitive, well it isn't for me when writing it, although one can guess
what it means when reading it, but perhaps that is the case for Hamcrest
too for other people. Additionally, if you ONLY know JUnit4, then a subset
of Hamcrest is already included inside the JUnit jar file. In essence, both
AssertJ and Hamcrest was a "solution" to the older JUnit assertion
In AssertJ, there seems to be a "bias" towards creating your own Unit Test
Assertion classes, so that the tests reads more nicely. And in Hamcrest,
the "bias" is towards creating a ever-growing library of generic assertions
independent of the unit tests at hand. IMHO, the former can still be done
in Hamcrest, but I have not seen that, and I have also seldom seen anyone
creating their own AssertJ assertion classes.
Across the Java community, more people are comfortable with Hamcrest than
AssertJ, probably due to Junit's inclusion of some of it.
My recommendation is to use JUnit4 + Hamcrest library + creating PLC4X
specific Matchers (if needed).
I spent this morning changing the AssertJ to Hamcrest across all tests. You
want a PR?
