Case Study: DirecTV achieves near‑100% regression coverage and 60–70% fewer escaped defects with Parasoft API Testing

Extreme Automation Enables DirecTV to ”Shift Left” API Testing

DirecTV’s Enterprise Integration team, responsible for the REST and SOAP APIs that connect billing, programming, and support systems, faced shrinking test windows as development velocity increased — risking defects that would directly harm customer satisfaction. They needed a way to maintain exhaustive, repeatable validation across disparate systems and through a multi-year middleware migration without slowing releases.

By adopting Parasoft’s API Testing solution and applying “extreme automation,” the team automated complex test construction, execution, and validation, integrating results into HP ALM and developers’ Eclipse workflow. In the same three-day window that once ran ~500 manual tests, they now run ~3,500 tests (adding 400–1,000 per release), with 5,000+ automated validations and nearly 100% regression coverage; escaped defects have fallen about 60–70%. Reusable, environment-agnostic tests speed migration, enable earlier developer testing, and let DirecTV deliver higher-quality releases faster.
