I see there are 3 (count'em!) underscores here.
It isn't really a full \__init__ test, but only tests the '.concrete' aspect, so arguably it should be called  "```Test___init____concrete```".
( as in "```Test_/name_of_public_method/__/aspect_of_method```" --> "```Test_/__init__/__/concrete```". )

In fact, a good job this has been renamed, or it would be "```Test___init_____concrete```".
Five in a row -- could this be a record ?? ;-)
