Case Study: Pacific Northwest National Laboratory achieves higher testing productivity and fewer bugs with Cypress

Pacific Northwest National Laboratory reduces test run durations by 75% with Cypress

Pacific Northwest National Laboratory (PNNL), a U.S. Department of Energy national laboratory, faced challenges with a slow and flaky open-source testing framework. This led to inefficiencies for their engineering team and an unacceptable number of bugs being shipped to production applications. The need for a reliable testing solution became paramount when developing RedEye, a critical data visualization application for cybersecurity operations.

PNNL implemented Cypress as their end-to-end testing solution, utilizing Cypress Cloud to run tests in their GitHub Actions pipeline. This provided deterministic test outcomes, a simplified developer experience, and accelerated debugging. The results were exceptional: the team achieved over 85% test coverage for crucial user stories, shipped only one trivial bug after the product trended on GitHub, and reduced overall test run durations by 75% through parallelization in Cypress Cloud.
