Introduction to AWS Device Farm

This lab provides the basic hands-on experience of AWS Device Farm Service, which provides a test harness for mobile app developers. It will demonstrate the basic steps required to load an example Android app and run a series of tests, using several common mobile device platforms from Samsung, LG, Amazon, and others.

Overview

This lab shows you how to use AWS Device Farm to test a sample Android mobile app. In this lab, you will use the AWS Device Farm console to create a project, upload a sample .apk file, run a suite of standard tests, and then view the results.

Topics covered

By the end of this lab you will be able to:

  • Create an AWS Device Farm Project
  • Upload a sample Android mobile app into the AWS Device Farm Project
  • Test the mobile app using a basic suite of tests in AWS Device Farm
  • View the results of the test suite run

Prerequisites

Some familiarity with mobile application development and deployment platforms, and concepts of application testing, will be helpful, but not necessary to run the lab.

AWS Device Farm Introduction

AWS Device Farm is an app testing service that enables you to test your iOS, Android and Fire OS apps on real, physical phones and tablets that are hosted by AWS. The service allows you to upload your own tests or use built-in, script-free compatibility tests. A test report containing high-level results, low-level logs, pixel-to-pixel screenshots, and performance data is updated as tests are completed.

Device Farm allows you to upload your own tests or use built-in, script-free compatibility tests. Because testing is automatically performed in parallel, tests on multiple devices begin in minutes.

Device Farm supports native and hybrid Android, iOS, and Fire OS apps, including those created with PhoneGap, Titanium, Xamarin, Unity, and other frameworks.

AWS Device Farm Terminology

Device Farm introduces the following terms that define the way information is organized:

  • project: A logical workspace that contains runs, one run for each test of a single app against one or more devices. Projects enable you to organize workspaces in whatever way you choose. For example, there can be one project per app title, or there can be one project per platform. You can create as many projects as you need.
  • run: A specific build of your app, with a specific set of tests, to be run on a specific set of devices. A run produces a report that contains information about the results of the run. A run contains one or more jobs. For more information, see the AWS Documentation for AWS Device Farm Runs.
  • report: Contains information about a run, which is a request for Device Farm to test a single app against one or more devices. For more information, see the AWS Documentation for AWS Device Farm Reports.
  • job: A request for Device Farm to test a single app against a single device. A job contains one or more suites.
  • suite: The hierarchical organization of tests in a test package. A suite contains one or more tests.
  • test: An individual test within a test package.

AWS Device Farm Test Types

Device Farm currently provides support for the following test types:

For Android:

For iOS:

If you do not have your own tests, you can use a built-in fuzz test. The built-in fuzz test randomly sends user interface events to devices and then reports results.

This hands on lab will demonstrate this feature. For more information on the tests implemented in Fuzz, see Built-in: Fuzz (Android and iOS).

Task 1: Locate or Download an Example Android *.apk or iOS *.ipa File

If you are a mobile developer, and you have a compiled Android *.apk or iOS *.ipa file that you would like to use for this lab to test, locate the compiled *.apk or *.ipa at this time.

If you do not have your own mobile app to test, below are some examples available publicly to test in this lab. These examples may move or change from time to time. The test results may vary and may not all pass or fail. Each will provide interesting test results nonetheless.

  1. Please download one of the following files to your computer:
  1. In the AWS Management Console, on the Services menu, click Device Farm.

  2. If you see Get started, click it.

  3. At the AWS Device Farm window, configure:

  •  Mobile Device Project
  • Click Create project

If you type a project name other than myProject, be sure to use it consistently throughout this lab.

Task 2: Upload and Test the Example Application

  1. Click  Create a new run

  2. On 1 - Choose application, configure the following:

  • Click the Android and Apple   icons
  • Click  Upload
  • Browse to and select the application that you downloaded.

AWS Device farm processes and analyzes the mobile app. A progress bar is displayed, and when complete, a summary of the analysis is presented.

  1. At the bottom of the screen, click Next step

  2. Ensure the following values set:

  • Test: Built-in Fuzz
  • Event count: 
  • Event throttle: 
  1. Click Next step

  2. On the Select devices page, click Next step

You will use the Top Devices pool.

A device pool in Device Farm represents a collection of devices that typically share similar characteristics such as platform, manufacturer, or model. For more information, see Devices.

You will skip specifying the device state. However, if you'd like, you can adjust the parameters on the Specify device state page. On the Specify device state, you can do any of the following:

  • Provide additional data for Device Farm to use during the run, next to Add extra data, choose Upload, and then browse to and choose the .zip file
  • Specify whether Wi-Fi, Bluetooth, GPS, or NFC will be enabled during the run, next to Set radio states, select the appropriate boxes
  • Preset the device latitude and longitude for the run, next to Device location, type the coordinates
  • Reset the device locale for the run, choose the locale in Device Locale
  1. In the left navigation pane, click Review and start run.

Task 3: Run Test and View the Run's Results

  1. On the Review and start run page:
  • Review your settings
  • Click Confirm and start run

Device Farm should start the run as soon as the requested devices are provisioned and available, typically within a few minutes. Until the run starts, Device Farm will display a calendar icon. After the run starts, results will appear as tests are completed. During this time, Device Farm will display a progress icon .

You'll know the run is complete when the progress icon changes to a result icon. Depending on the complexity of the application, a full test run can take from less than a minute to ten minutes or more.

  1. Click the test result to view the run's results.

A summary page that includes the following information is displayed.

  • A list of devices and test results for each
  • The total number of suites, by outcome
  • Lists of tests with unique warnings or failures
  • Screenshots captured during the run, grouped by device

Conclusion

 Congratulations! You now know how to:

  • Create an AWS Device Farm Project
  • Upload a sample Android mobile app into the AWS Device Farm Project
  • Test the mobile app using a basic suite of tests in AWS Device Farm
  • View the results of the test suite run

Additional Resources

Logging AWS Device Farm API Calls by Using AWS CloudTrail

Device Farm is integrated with CloudTrail, a service that captures API calls made by or on behalf of Device Farm in your AWS account and delivers the log files to an Amazon S3 bucket you specify. Examples of these API calls include creating a new project or run in Device Farm. CloudTrail captures API calls from the Device Farm console or the Device Farm APIs. Using the information collected by CloudTrail, you can determine which request was made to Device Farm, the source IP address from which the request was made, who made the request, when it was made, and so on.
