Development Edition
Microsoft Visual Studio Team System 2008 Development Edition provides developers with an advanced set of tools to identify inefficient, insecure or poor-quality code, specify coding best practices and automate software unit testing. These tools help team members write better-quality code, reduce security-related issues and avoid bugs later in the development lifecycle.

Unit testing with code coverage to test code early and often and measure the effectiveness of your tests
