In the blog Functional/System testing with Visual Studio/Test Manager we talked about unit testing. Testers in the near future are going to need unit testing skills. Now that is a very scary statement given 70% of testing is done manually. Now is the time to start learning by taking programming courses, unit testing courses, pairing with developers to learn and searching the web.
In the Visual Studio magazine Jeff Levinson article Take Unit Testing to the Next Level talks about how to add unit tests to requirements to show test coverage. Jeff supplies code you can download and instructions on creating simple unit tests then how to link them to requirements. If you have Visual Studio give it a try.
