Just released a new version of AE, aka Assertive Expressive, a modern assertions system that can be used with any test framework. This release improves the API by moving AE’s Assertion and Assertor classes into the AE namespace where they belong. It also improves how test frameworks tie into AE, doing away with the use of Kernel extensions for the purpose, and utilizing a toplevel constant (Assertion) to dynamically reference the exception class used by a test framework to raise assertion errors.
