saucectl Architecture

This document provides an overview of the saucectl CLI architecture to help you better understand how it works.

Architecture Components​

The following provides a high-level overview of the saucectl CLI architecture.

  1. saucectl sends the test payload (mobile app, test app, or project files) to the app storage.
  2. Depending on the capabilities of the underlying test framework (e.g., Playwright or Espresso), saucectl will call the appropriate device cloud that is capable of running your tests.
  3. The device cloud allocates a device for your request, retrieves the payload from app storage, and runs the tests.

This diagram illustrates at high level how saucectl interacts with the Sauce Labs environment.
