Case Study: Leading Financial Services Organization achieves 85% code coverage and major developer productivity gains with Parasoft Jtest

AI-Driven Java Unit Testing Boosts Developer Productivity for Financial Firm

A leading multinational financial services firm managing hundreds of Java microservices faced mounting DevOps pressure to speed delivery while improving quality. Much of the estate was legacy code with low test coverage, which correlated with higher defect rates; developers were spending excessive time manually creating unit tests, causing late-cycle rework and unpredictable timelines.

The company piloted and adopted Parasoft Jtest’s AI-enabled unit testing—using one‑click test generation, an IDE Unit Test Assistant, test impact analysis, aggregated coverage views and Spring support—to automate and focus testing. In a few weeks they raised coverage on critical services from ~20% to 85%, doubled the speed of unit-test creation, cut CI/CD regression test time by 90%, reduced defects by over 20%, reclaimed 4–10 developer hours per week (≈20,000 hours/year for 100 devs) and achieved ROI in under three months.
