Steve Trefethen may be an ex-CodeGear employee, but he is still adding significant value to the developer community as a whole. Looks like he's started a series of posts where he'll talking about test automation and the advantages it gives you. Sure, everyone knows about unit-testing (at least you should), but Steve is talking about a much more holistic approach to automated testing. Here at CodeGear we have a significant internal investment in automated testing tools, especially for Delphi. So much so that we have several patents related to the technology. There are also a lot of excellent automated testing tools out there, such as TestComplete by AutomatedQA. I'm sure there will be some excellent information as he delivers the blog postings.
