The team at PlanetScale successfully migrated all integration tests written in Python to Go over a period of four months, resulting in improved ease of use and contribution for open source Vitess. The project required the development of a test framework in Go that could support running multiple tests in parallel without port conflicts, among other features. This migration has also led to improvements in the CI pipeline for Vitess, enabling larger compute+memory instance types, no limit on concurrent jobs, and quicker feedback on pull requests. These changes make it easier and faster to develop new integration tests and get started with contributing to the project. The end result is a more reliable and efficient development process for the open source Vitess community.
