To add some more recent developments, there have been some discussions on adding assert_raises_with_message to minitest in the past without much luck.

Currently, there is a promising pull request waiting to be merged. If and when it gets merged, we will be able to use assert_raises_with_message without having to define it ourselves.

In the meanwhile, there is this handy little gem named minitest-bonus-assertions which defines exactly that method, along with few others, so that you can use it out of the box. See the docs for more information.
