SOFTWARE VERIFICATION & VALIDATION

The document discusses two software verification and validation tools: NUnit and HP LoadRunner. NUnit is a unit testing framework for .NET that provides features like assertions, setup/teardown functionality, and test runners. It is used to verify code meets specifications. HP LoadRunner performs load and performance testing to validate systems can meet service level agreements under certain user loads. It generates virtual users, runs tests via a controller, and provides analysis to identify bottlenecks. Both tools are used in later software development phases like implementation and verification to help ensure quality.
