AWS has introduced parallel test execution in CodeBuild, addressing the issue of prolonged test execution times in continuous integration workflows. This feature enables developers to run test suites concurrently across multiple environments, thus speeding up the process. By allowing tests to be distributed intelligently using strategies like equal distribution and stability, developers can optimize their CI pipelines, shortening feedback loops and enhancing productivity. This innovation reflects AWS's commitment to improving developer experiences in increasingly complex project environments.
Parallel testing lets us do more while waiting less. It's an essential tool to keep sharp and ready so we can always establish a fast feedback loop.
CodeBuild provides environment variables to identify the current node and the total number of nodes, enabling intelligent test distribution.
