I've been working on an extensive update to a series of articles originally published in Clarion Magazine and titled "The Problem With Embeds". That series introduced the utility that became ClarionTest and demonstrated how to use automated testing in conjunction with classes to convert single-use, hard-to-test (and buggy) embed code to reusable, reliable, easily testable code. The rewrite is under way, but Parts 1 through 5 are now available.
