SimplePractice, a healthcare practice-management SaaS with a 20-plus developer engineering team, wanted to shorten total build times without heavy setup and maintenance overhead.

The solution

The team used Semaphore's parallel test workers to distribute tests and reduce total build time versus its prior file-size-based grouping approach.

The results, in context

SimplePractice reported decreasing total build time by around 15-20% using Semaphore's parallel test workers compared with its previous parallelization approach. The figure is quoted from Semaphore's published story and dated January 21, 2020.
