Case Study: United Guaranty reduces development risk, cuts testing costs, and expedites loan processing with Parasoft Jtest

United Guaranty Reduces Development Risks, Cuts Testing Costs, and Expedites Loan Processing

United Guaranty, a leading mortgage insurance provider, set out to transform from paper-based underwriting to a fully online service with its Java J2EE Ml Guide platform to speed loan origination and reduce costs. Early deployments suffered reliability problems—most notably connection leaks that caused intermittent downtime—which threatened availability and the company’s aggressive delivery schedule.

United Guaranty integrated Parasoft’s Jtest into its automated build process, created custom rules, and enforced code compliance before integration testing; Jtest now scans for over 60 error types. The tool helped find and fix 500+ critical errors, freed developers to spend at least 10% more time on new features (equivalent to four developers), saved roughly $440,000 annually, and delivered the stable, high‑availability applications needed to expedite loan processing and support the company’s online business model.
