Case Study: PSCU (the nation’s premier credit union service organization) achieves 100% faster unit test generation and 85% code coverage with Parasoft Virtualize

PSCU Accelerates Unit Test Generation by 100% With Simulated Test Environments

PSCU, a St. Petersburg–based credit union service organization supporting 2,400+ financial institutions and more than 8 billion annual transactions, struggled to fully test its 400+ APIs due to heavy third‑party dependencies. Those dependencies led to testing-in-production, limited unit test generation (around 30% code coverage), slow rollouts, and long waits for customized test environments—hindering Agile delivery and increasing time to fix issues in production.

PSCU adopted Parasoft Virtualize to simulate third‑party services and generate virtual assets on demand, eliminating environment wait times and enabling comprehensive, repeatable tests. The result: unit test generation accelerated by 100%, code coverage rose from 30% to 85% within weeks (exceeding the 80% industry average), builds now enforce an 85% coverage gate, and development and CI/CD cycle times were significantly reduced.
