Test Tools Overview

Open Beta Documentation Amazon offers this technical documentation as part of a pre-release, open beta. The features described might change as Amazon receives feedback and iterates on the features. For the most current feature information, see the Release Notes.

Testing your app thoroughly and continuously ensures it delivers a seamless experience and meets platform standards. This page explains how to use Vega's testing tools throughout your development process.

The following tools support different testing needs during app development:

IAP App Tester

App Tester allows you to unit test the In-App Purchasing (IAP) functionality of your app in sandbox mode before you submit the app for publication.

Appstore DevTest

Use Appstore DevTest when implementing and testing In-App Purchases (IAP). The tool manages test users, validates purchase flows, and simulates transactions. DevTest logs all test results and transactions to help you verify IAP functionality works correctly.

Appium

Appium is an open-source automation framework that enables user interface (UI) testing across mobile, web browsers, desktop apps, TV interfaces, and Vega (through Appium Vega Driver). By using the Appium Inspector tool, you can inspect apps and create custom test scripts to validate core functionalities on both physical and virtual devices. The scripts seamlessly integrate with test runners, reporting tools, and CI/CD pipelines.

Live App Testing

Before full release, use Live App Testing to validate real-world scenarios. The tool helps manage testers, test IAP flows at scale, and collect usage data. You receive detailed feedback reports and performance metrics from actual users.

Best practices

Begin your testing strategy early in development using Appium to write functional, regression, and end-to-end tests.
Create thorough test cases covering core functionality, edge cases, and error scenarios.
Document your testing process and success criteria.
Test across multiple devices to ensure consistent behavior.
Test IAP flows immediately after implementation.
Maintain testing baselines and isolate testing resources.
Track test results consistently and address any issues promptly.
Regularly update test cases for new functionality and edge cases
Engage real users through Live App Testing before submission.
