Parallel Testing Calculator

Parallel testing allows you to run multiple tests simultaneously across various browsers, devices, and OS combinations. This approach enables more tests to be run at once, significantly decreasing overall testing time. Faster build times mean faster releases and less time spent waiting for builds to complete.

Use this calculator to understand how parallel testing can help you achieve your test coverage and build execution time goals. Simply input your current testing setup and desired build time to calculate the optimal number of parallel tests needed.
