# Parallel testing using Cloud Runner

Parallel testing using the Cloud Runner involves execution of tests within a suite in parallel.

Parallel testing of the tests within a single suite starts as soon as you run the suite. When you run a suite using the Cloud Runner, all the tests within the suite run in parallel ignoring the execution order and abort on failure. Parallel testing using Cloud Runner is different from parallel testing without Cloud Runner.

**Note:** Parallel testing without Cloud Runner involves running of more than 1 suites in parallel.
