Automated Functional Equivalence Testing

This presentation is among the Top 27 Best Papers/Practice/Tutorials selected, out of 460+ submissions received, to be presented @STC 2012.

Presentation Abstract

Migration from legacy Visual Basic 6.0 to VB.NET or Java technology is gaining momentum as Microsoft has stopped providing support for VB6. To take benefit of newer technology and hedge risk, companies are migrating applications to .NET or Java technology. Migration projects are testing intensive. Challenge is how to ensure that functional equivalence on target application has been achieved. There aren’t too many tools that are available in the market that can be used for functional equivalence.

This Paper focuses on the methodology and techniques that Datamatics Global Services has developed to automate functional testing, when source VB project gets migrated to .NET.
This approach ensures reusable, smooth and cost effective way to achieve 100% functional Equivalence testing on any migration project.
