Before you get started with application testing, you need to get some applications installed on your Windows or Mac computer and ensure these applications are running properly. Please refer to the Installation Guide for detailed list of installations on Windows and Mac.

On your Windows computer:

• Ensure you have installed Appium, Node JS, and downloaded Android command line tools.
• Ensure you have downloaded required Android APIs using SDK Manager.
• Create or define Android device specifications using AVD Manager in case you want to use Android simulators to test your Web or Native applications.
• Start Appium by running the "appium" command in the Command Prompt window.
• Ensure you have enabled Developer Option and USB Debugging options on your Android device. For more information please refer to the section, Connecting Mobile Devices with Computer.
• Connect Android device with Windows computer and ensure it is connected properly with computer by running the "adb devices" command in the Command Prompt window. Make sure your device is listed here (emulator or physical device connected with Windows computer).

On your Mac computer:

• Ensure you have installed Appium and Xcode.
• Ensure you have downloaded required iOS simulators using Xcode.
• Ensure you have set the iOS App Path and selected desired device in the iOS Settings window in Appium (when testing iOS applications).
• Ensure you have enabled Web Inspector and JavaScript options on your iOS device (for Web application testing).
• Connect iOS device to your Mac. To ensure device is connected properly to Mac, open Simulator and on the Hardware menu, point to Devices and then click Manage Devices. Make sure device connected with Mac is listed in the left pane.
