Visual Basic for Testers [PDF ebook] 

The goal of Visual Basic for Testers is to teach you how to use Visual Basic to increase your level of sophistication as a tester. You’ll learn how to use VB to write an automated testing project and what to look for in a well-written VB program. Author Mary Sweeney will help you gain the experience necessary both to use VB to support an automated text project and to text a commercial application written in VB.Since testers often want to move to development tracks, Sweeney also presents information on programming and the issues involved in maintenance and debugging.
