Starting with IG-XL version 10.40, the new feature, .NET Development in IG-XL, will support the ability to alternatively write test methods in the VisualBasic.NET language. The Microsoft .NET environment consists of a rich and powerful programming ecosystem and utilizes the Microsoft VisualStudio IDE for highly efficient code development. Flexible concepts for code modularity, reuse, refactoring and maintenance – well-recognized throughout the software industry – can now efficiently be applied to create and maintain IG-XL based test programs. This presentation highlights some of the most fascinating features and demonstrate how they are used. With examples selected to have a strong ATE relevance, the audience will learn how to apply these techniques to their workflows for better code quality and more efficient project execution.
