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.

Salesforce DX Setup

Set Up Your Development Environment for Lightning Web Components
Set Up Your Development Environment for LWC Offline
Preview Lightning Web Components on Mobile
Set Up Xcode (required for iOS simulator)
Set Up Android Studio (required for Android emulator)

You don’t need to set up both Xcode and Android Studio unless you want to use Test Harness in virtual devices on both platforms.
