As WordPress Playground continues to mature, it has become a viable testing alternative to local test/staging sites. New testers benefit from free and instant access to a WordPress environment, and even experienced testers can appreciate transient instances for tasks ranging from smoke tests to Gutenberg PR testing.

The Test Handbook should include an informational "how to" page that guides testers in the use of Playgrounds for testing and triage, highlights its strengths and limitations, and offers known solutions/workarounds for certain test scenarios (e.g. setting wp-config.php values via the Blueprints API).

This new page would be Test Team-focused, and be cross linked with existing "getting started" environment setup and Contributor Day content.
