Sorry, I must have accidentally deleted the line when I deleted empty
lines to make the example more compact.

Yes, that works indeed. But in practice the modules_to_import list is
filled by parsing the contents of a test/*.py directory. That's why I
import dynamically with __import__.
Nevertheless, you got me on the right track. After I explicitly added
the modules to the global namespace (globals()["mytest"] =
__import__("mytest")), it works fine. Thx!
Best,
