Here is where a Mobile Device Testing Lab makes sense.

Mobile testing lab ensures that your mobile app works impeccably on different devices and under diverse conditions. This article will examine the need for mobile device testing and how to build a great test lab that will result in improved app performance.

What Exactly is Mobile Device Testing Lab?

The term mobile device testing lab refers to a highly controlled environment consisting of several smartphones, which are primarily used to test websites, applications, and other mobile services. Such a lab would essentially create a simulated scenario in which the testers can test the behavior of an app or service in different device types, operating systems, and network environments.

In simple terms, a Mobile Device Lab is a designated area where a variety of mobile devices are placed for testing purposes, mainly software applications and websites. Such labs help developers and QA testers make sure that their products are optimized for different device configurations and OS combinations.

Building a Device Lab Typically Involves:

  • Hardware collection: Assembling a range of smartphones and tablets representing the market’s major brands, models, screen sizes, and operating systems.
  • Dedicated testing space: Establish a spacious, calm location where these devices can charge, be accessed, and be tested easily.
  • Monitoring systems: Software that can help in managing these devices and monitor tests, errors, and other activities.
  • Software Requirements: In order to manage and automate the testing process, you’ll need mobile testing software. The use of tools such as Appium, Calabash, and Xamarin can be helpful in both manual and automated testing.

Setting Up an Environment for Testing Mobile Applications

Testing environments are like labs for testing the effect of different elements on the end-user experience, so it depends on how they are set up and whether your tests will be successful. In order to set up an environment for mobile app performance testing, you should take the following steps:

  1. The Environment Should be Isolated.

As part of the testing, it’s important to know how many users are simultaneously operating and what operations they are performing. If two teams perform parallel tests in the same environment, test results could be compromised, and the process could be slowed. The isolation of the environment guarantees the accuracy of the experiment and keeps it precise.

  1. Make Use of Test Data Generators.

It is important to pay attention to the actions of writing, reading, and deleting data, as these operations could halt the app to its fullest potential. To simulate real-world data without copying sensitive data from the production environment, you can use data generation tools, such as Datprof or EMS Data Generator.

  1. The network should be isolated.

It is impossible for most networks to support multiple concurrent activities without affecting the application’s performance. Therefore, it is highly recommended, even if it is not an absolute must.

  1. Take Proxy Servers Off the Network Path.

An application can suffer from performance issues if a proxy is used between the client and the server. It may be possible to solve the problem by conducting tests in an isolated environment.

How Mobile Testing Can Help Your App?

It is important to note that currently, apps must be tested on a plethora of mobile devices and operating systems to ensure compatibility, usability, and consistency. Automation testing can be used to develop applications that are scalable and accessible.

Regression and performance testing is a repetitive task that can be easily done by automation since manual testing is time-consuming, costly, and prone to errors.

The testers will use automated testing that will enable them to validate the new or recent updates or changes in the application for errors, defects, and vulnerabilities with speed. Additionally, it helps them to:

  • Run multiple tests in parallel on different devices.
  • Reuse tests
  • Get enhanced coverage
  • Achieve better ROI
