Finally recognizing that non-enterprise developers want access to integrated unit testing, Microsoft has made some of its unit testing functionality available in Visual Studio Pro.
Microsoft first offered unit testing in Visual Studio 2005 Team System, along with integrated static analysis and code coverage tools. While a step in the right direction, Microsoft’s offerings are still rather limited and focused more on developers than on test engineers.
One troubling aspect of the current trend is towards unit testing is that lack of emphasis on other testing methods. Unit testing is really only part of the overall test plan for a professional grade application, and studies demonstrating its effectiveness are not readily available.
