# Testing

> Test API commands and device responses with the Command Testing Suite.

The **Testing** tab (Test → Command Testing Suite) lets you test your product's
API commands and inspect device responses — a focused harness for verifying that
a command does what you expect before you ship.

## What you do

* Pick a command your product defines (see [API Commands](/studio/api-commands))
* Provide test parameters
* Send it and inspect the response
