Comment (by ghseeli):
Alright, I added some negative unit tests. However, I am now having
trouble getting the following test to pass:
{{{
sage: R.<x> = QQ[]
sage: BA = BrauerAlgebra(2, x, R)
sage: BA.ambient().has_coerce_map_from(BA)
True
}}}
However, when I run these commands in Sage, the result comes out as
expected. Any ideas on why this is happening?
