Install the Test Harness App

Test Harness is distributed as an installable app package, not via the Apple App Store or Google Play Store. As a developer tool, it’s intended to be installed into and used with a working development environment. The installation process, prerequisites, and compatibility details are consequently a bit more involved than with a normal mobile app.

Test Harness Prerequisites

To make full use of Test Harness, you need a complete working mobile development environment. If you haven’t set up your mobile development tools yet, see the following resources for guidance.
