Mobile Testing Case Study: Why It Matters in App Development

Mobile testing is the process of testing software applications developed for mobile devices. Today, mobile applications have become an integral part of businesses, and it's rare to find a business venture that functions without a mobile application.

According to Transparency Market Research (TMR), the adoption of test automation will be boosted by the growth in mobile applications. Here's why mobile app testing is critical for enterprises today.

Mobile Testing Case Study: Why Mobile Testing Matters in App Development

  1. Mobile Application Testing is Strategic: Mobile Application Testing enables enterprises to build applications that are scalable and accessible across multiple platforms. It’s a process to build an application software by testing it for its functionality, usability, and consistency. This can be done by automation as well as with manual testing.
  2. The Need for End-to-End Testing: Mobile applications are getting complex, and there is a need for end-to-end testing. Right from whether the application is downloadable effectively, works seamlessly, and gives the same kind of experience across various devices.
  3. The Increasing Proliferation of Mobile Applications: The increasing proliferation of mobile applications across multimedia travel, communications, utilities, and productivity is presently identified as a key factor in the test automation market. Besides these, the increasing deployment of cloud applications is also bolstering the scope of the test automation market.

Mobile Testing Case Study: What Do We Need to Consider When Preparing a Testing Strategy?

When preparing a mobile testing strategy, it is important to consider the following:

  1. Determine the right combination of manual and automation testing.
  2. Create separate suites for manual test cases and automated test scripts as needed.
  3. Identify reusable automation scripts and modify them as required.
  4. Consider using a nine-step checklist for creating a mobile app testing strategy.

Introduction to 3 Different Types of Test Cases

1. Functional Testing Test Cases

There are a lot of hands involved in creating a mobile app. These stakeholders may have different expectations. Functional tests determine if a mobile app is in compliance with these various requirements and uses. It examines and validates all functions, features, and competence of a product. Here are twelve functional test case scenarios questions:

Is the application working as designed whenever it starts and stops?

  • Does the app perform accordingly on various mobile and OS versions?
  • Does the app behave accordingly when faced with external interruptions? (e.g. receiving an SMS, minimized during an incoming phone call, etc)
  • Is the user able to download and install the app without issues?
  • Is the device able to multitask as expected when the app is in use or running in the background? • Can other applications perform satisfactorily once the app is installed?
  • Are social network options such as sharing, posting, etc. working as required?
  • Are mandatory fields working as required?
  • Does the app support payment gateway transactions?
  • Are page scrolling scenarios working as expected?
  • Can you navigate between various modules as expected?
  • Are appropriate error messages received as necessary?

There are two ways to run functional testing: scripted and exploratory. And when it comes to the tools, try the APP Functional Testing by WeTest, which is a professional testing service provider with an expert team experienced in various industries. They provide fast and in-depth functional testing services, covering top models and complete test scenarios. Results are presented clearly in a professional report.

2. Performance Testing Test Cases

Performance testing ensures that the app is stable and performs well under various conditions, such as heavy loads and network changes. Here are some performance testing test cases to consider:

  • Can the app handle projected load volumes?
  • What are the various mobile app and infrastructure bottlenecks preventing the app from performing as expected?
  • Is the response time as expected?
  • Is battery consumption, memory leaks, GPS, and camera performance within the required guidelines?
  • Is the current network coverage able to support the app at peak, average, and minimum user levels?
  • Are there any performance issues if the network changes to/from Wi-Fi and 2G/3G/4G?
  • How does the app perform during intermittent phases of connectivity?
  • Are existing client-server configurations providing the optimum performance level?

3. Compatibility Testing Test Cases

Imagine your app on different devices, with different operating systems, sizes, and resolutions. Will it work just as well on all of them? That's where compatibility testing comes in. By testing the app across various platforms and environments, you can ensure that it works consistently no matter where it's used. Here are some specific compatibility testing test cases to consider:

  • Have you tested on the top mobile app testing devices and operating systems?
  • How does the app work with varying parameters, such as bandwidth, operating speed, and capacity?
  • Does the app work properly with various mobile browsers like Chrome, Safari, Firefox, and Microsoft Edge?
  • Does the app’s user interface (UI) remain consistent, visible, and accessible on various screen sizes?
  • Is the text readable for all users?
  • Does the app work seamlessly across various configurations?
