Allows to test uniqueness of members of a list

-0 on this one because the algorithm is quadratic, the name is opaque, and because the common case can already be clearly expressed with sets.

It looks pretty niche. I do not remember a single case in which such method would help.

Indeed, can do 
assertNotEquals(len(the_list), len(set(the_list))

I think you meant assertEqual(len(alist), len(set(alist))).  I agree with others.

Of course. Wanted a shortcut. Can close it if you want.
