Test Orchestration
Test orchestration coordinates the execution of many different tests — across suites, environments, and stages — managing scheduling, parallelization, dependencies between test stages, and result aggregation, so a complex pipeline of tests runs efficiently and reliably rather than as a fragile, manually sequenced process.
As a pipeline grows to include unit, integration, end-to-end, performance, and security tests across multiple environments, simply running them all in one long serial sequence becomes impractically slow — orchestration determines what can run in parallel, what must wait for a prerequisite stage, and how failures in one stage affect whether later stages run at all.
CI/CD platforms (GitHub Actions, GitLab CI, Jenkins) provide the underlying orchestration primitives — job dependencies, parallel matrix builds, conditional stages — but designing an efficient test orchestration strategy on top of those primitives is a real engineering discipline of its own, not just default configuration.
