AWS CodeBuild now supports test splitting and parallelism

You can now split your tests and run them across multiple, parallel-running compute environments. Based on your sharding strategy, CodeBuild will divide your tests and run them across the specified number of parallel environments. AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs tests, and produces ready-to-deploy software packages.

As the number of tests in a project grows, the total testing time also increases when using a single compute resource. Running tests in parallel across multiple compute resources reduces the overall testing duration in your CI/CD pipeline. This leads to faster feedback cycles and improved developer productivity.

The parallel testing feature is available in all regions where CodeBuild is offered. For more information about the AWS Regions where CodeBuild is available, see the AWS Regions page.
