The text discusses the importance of faster feedback loops in software development, particularly in agile development and CI/CD workflows. It highlights the need for pre-merge and post-merge tests to maintain system health, but acknowledges that running all tests can be time-consuming and slow. The authors propose dividing tests into "pre-Merge" and "post-Merge" buckets, with faster pre-merge tests catching bugs early and more stable post-merge tests ensuring code health after deployment. They also introduce the concept of a merge queue, which acts as a gatekeeper, managing code merges and orchestrating the deployment process. The merge queue validates changes before merging them into mainline, allowing for fast feedback to developers while maintaining system stability. This approach improves developer productivity by providing faster feedback loops and reducing the impact of failed tests on the development cycle.
