Case Study: Trane Commercial achieves a smooth C++ migration and faster, higher-quality development with Parasoft’s Development Testing Platform

Trane Smoothly Transitions to C++ Aided by Parasoft’s Development Testing Platform

Trane’s Global Modeling and Analysis team, responsible for the company’s mathematical models, moved from a long‑running legacy system to object‑oriented C++ to enable component reuse, multiple user interfaces, and faster responses to business needs. To meet Six Sigma requirements and maintain uniform reliability, performance, and maintainability standards, the team sought a way to automate code review and validation because manual reviews threatened the project schedule and budget.

They adopted Parasoft’s Development Testing Platform for C++ and .NET, gaining automated unit testing, Visual Studio integration, C++ static analysis, and reusable tests with nearly 100% coverage. The platform caught errors early, reduced debugging and downstream costs, taught developers best practices, enabled regression testing, and freed the team to spend time adding new features.
