While writing minitests or rspec tests in Rails many of us might have or might want to see if the error and it’s message is reported by the application or if some custom error and its message match with the one we added ourselves.

rails test test/models/example_test.rb -
After this change now it is possible to do the above thing in a much cleaner way without having to store it in a variable.

assert_raises instead of having to use both
assert_match for doing the same.
