Stop waiting for your tests by making them 3x faster

This post introduces the concept of running tests in parallel across multiple workers to achieve significant speedups (3x faster). It contrasts the cost of parallel testing on other platforms (Travis, CircleCI) with the affordability of self-hosted runners with GitLab CI. It also announces free CI hosting for private projects on ci.gitlab.com and offers cloud hosting credits (Google Cloud Platform, Digital Ocean) for users to set up their own runners.
