Test Parallelization helps you reduce CI testing time by distributing test files across CI nodes or local workers. It uses Test Optimization data to detect which test files should run, estimate their duration, and create an execution plan. When used with Test Impact Analysis, Test Parallelization runs only files with non-skipped tests. It also helps reduce CI costs by choosing only as many CI nodes as needed, which can reduce CI resource usage.
To qualify for this Product Preview, you should already be using Datadog Test Optimization for Ruby.
