You probably are using automatically registered test units. These are registered
in single shared test framework as soon as you load these libraries and they are
loaded in memory as they are dependencies of the library you want to test. Thus
you end up with all test units in all loaded libraries.

You can specify the test case belonging to the Mydll1 using --run=TestMyDll1 and
you'll get only 1 test case being executed.

I think this is correct behavior overall. What you got here is implicit
dependency between test units you can't be sure TestMyDll1 working until you
tested all of it's dependent test cases which are in this case reside in
corresponding libraries.
