​
Region

Each project runs in one AWS region. Empirical currently supports: Region selection is managed by Empirical. Contact [email protected] if your tests should run in a different supported region.

​
Shards

Sharding splits a suite across parallel workers to reduce run time. A project’s configured shard count is a maximum from 1 to 50; smaller filtered runs may use fewer shards so workers are not started with too little work. The run report shows each shard’s progress and logs. The public trigger API does not expose a shard override, and regular project members cannot change the project maximum in the dashboard. Contact [email protected] to adjust it.

​
Report notifications

Use Settings → Reporters to enable email reports and configure GitHub reporting. Use Settings → Slack channels to choose which connected channels receive reports and for which environments. When starting or rerunning a test from the dashboard, use the Notifications tab to choose whether that individual run sends report notifications. This setting does not change the project’s reporter configuration. See Slack notifications for notification behavior and Slack setup for channel setup.
