Case Study: DHL Parcel reduces test execution time by 65% with Cypress Cloud

DHL Parcel cuts test execution time by 65% with Cypress

DHL Parcel, a leading global parcel delivery provider, relies on a sophisticated software infrastructure that requires robust automated testing to support its high-volume operations. Their software team, which performs over 400 deployments annually, faced a significant challenge as their Cypress test execution times were exceeding build durations. This hindered development velocity and made engineers reluctant to add new tests. Initial attempts to improve efficiency through parallelization introduced new problems like unbalanced test suites and wasted CPU capacity.

The solution implemented using Cypress Cloud focused on optimizing parallelization. By configuring additional machines in Jenkins and utilizing Cypress's automatic test time monitoring, the team identified key areas for improvement. They further optimized CPU load and integrated Docker Compose with a Cypress image to seamlessly manage test execution. As a result, Cypress helped DHL Parcel reduce its test run time by 65%, from over 7 minutes down to just 3.5 minutes. This led to a notable increase in feature coverage and enhanced overall testing satisfaction.
