[PATCH 0 of 1] progress counter when running tests

[Idan Kamara]

not sure if this is really wanted but I often find myself wondering how many tests are left to run.
this adds a progress counter every 10 completed tests.

before:
..................................s.......................sssssss..

after:
..........[10/413]..........[20/413]..........[30/413]....s.....[40/413]..........[50/413]........ss[60/413]sssss..
