More information about that one: minitest 5 requires everything that includes MiniTest::Assertions to provide an "assertions" accessor. See minitest/minitest#286

A word: I'm trying to take over the maintenance of flexmock. It's unfortunately bit-rotting since Jim's passing, and that's really a pity - both for his memory as a great contributor to Ruby's community and as a really nice piece of software.

I've fixed that particular issue, as well as added minitest-specific support and some other things
there: https://github.com/doudou/flexmock. I'm going to try and get the rights to push new gems versions, but I really don't know if it's going to happen.
