> PS: What has failed for you in `sage -t
src/sage/rings/finite_rings/integer_mod_ring.py`?
The failures do not look deterministic. With the current state of your
branch, all tests passed when I did `sage -t integer_mod_ring.py` for the
first time. Then I tried again and repeatedly got:
{{{
$ sage -t src/sage/rings/finite_rings/integer_mod_ring.py

Integers(15).fraction_field()
Expected:

TypeError: self must be an integral domain.
Got:
Ring of integers modulo 15

sage -t src/sage/rings/finite_rings/integer_mod_ring.py # 1 doctest

}}}
But I'm unable to reproduce this behaviour from the sage command line.
I will run the tests again after rebuilding sage from scratch.
