.NET helper classes serve as an interface between Silk Performer’s BDL language and the .NET language. Although Silk Performer is able to call the .NET Framework through the basic functions that it offers, helper classes are required to enable .NET to call back to Silk Performer. With helper classes, which are generated automatically with .NET Explorer and the Visual Studio .NET Add-On, .NET developers can take full advantage of developing test code in .NET and don’t need to learn BDL. The test code that developers deliver to QA, by making use of helper classes, can be called from Silk Performer or scheduled in load tests using Silk Central.
