Regression Testing in Mobile App Development

In this article, we will discuss what regression testing is, its importance in mobile app development, and how to perform regression testing on a mobile app.

In recent years, the demand for mobile apps has exploded. With an app for just about everything, the need for mobile applications that are efficient, functional, and user-friendly is at an all-time high. However, developing an app that meets all of these requirements can be a complex process. There are numerous steps involved in taking an app from the initial development stages to its deployment in the market. One of the most critical steps in this process is mobile application testing.

Mobile application testing is the process of assessing a mobile app’s functionality, performance, and user experience across various devices and operating systems. It is an essential step in ensuring that an app performs optimally and provides a seamless user experience to all users. Regression testing is a crucial component of mobile application testing.

What is Regression Testing?

Regression testing is the process of re-running functional and non-functional tests to confirm that previously designed and tested software continues to work after a change. In other words, it involves testing an application to ensure that any new feature releases or updates do not affect the existing functionality of the software.

The primary goal of regression testing is to ensure that the software remains stable, even after multiple updates and releases. With the rapid pace of technological advancements, regression testing has become an integral part of testing to ensure that mobile apps provide optimal user experience across multiple devices and operating systems.

Things to Consider for Regression Testing:

It is essential to consider the following important things while doing regression testing.

Mobile Devices and OSs used by End Users

One of the essential factors to consider in regression testing is the variety of mobile devices and operating systems used by end-users. To ensure that your app is effective, it should be tested on as many platforms or devices as possible. However, this may add complexity to the testing process, especially if your target customers use diverse devices and operating systems.

Therefore, it is crucial to gather information about the target customer’s devices and operating systems before beginning regression testing. This information will help you design an effective testing strategy that accounts for the range of devices and operating systems used by your customers. It is recommended to start with a core user base and gradually extend testing to cover a broader range of devices.

Work on Critical Application Flows

Critical application workflows are the primary paths that end-users follow to complete tasks using your app. These critical journeys are the most commonly used processes in the app, and it is essential to test them thoroughly during regression testing. This helps to ensure that the app functions correctly, is secure, and that users can complete their tasks smoothly without any issues.

Consider Multiple User Conditions

Mobile devices are often used in various conditions and situations. Regression testing should consider these conditions to ensure that the app functions correctly. The app’s performance may be affected by network conditions. These conditions include low or unstable network connectivity and interruptions from other apps, phone calls, and SMS.

Testing under various conditions can provide insights into how the app functions in real-world scenarios. This helps to ensure that the app performs well under all conditions. This information can help developers identify issues and fix them before they affect users.

Parallel Testing

Parallel testing is a powerful testing approach that can help companies save time and money by testing multiple versions or components of an application simultaneously on different systems using the same data. This method is crucial in regression testing and provides cloud scalability to support multiple transactions per day.

By executing tests in parallel, businesses can save valuable time and reduce costs associated with testing. It is essential to consider the number of tests running in parallel and the frameworks that best suit your needs, based on the skill sets of your developers, engineers, and manual testers.

Importance of Regression Testing in Mobile App Development

Regression testing is an essential component of mobile app development as it ensures that the software remains functional, even after multiple updates and releases. When an app undergoes multiple updates, it can introduce new bugs, which can affect the overall functionality and user experience. Regression testing is crucial in identifying these bugs and finding timely solutions to fix them.

Here are some of the key reasons why regression testing is critical in mobile app development:

  1. Ensures the stability of the app: Regression testing ensures app stability even after multiple updates. App stability is crucial because it guarantees that users can use the app without major bugs or crashes.

  2. Reduces development costs: Regression testing can identify bugs and issues early in the development process, reducing overall development costs. Fixing bugs during later stages of development can be expensive as it may require rewriting entire sections of the code.

  3. Improves user experience: By ensuring that an app remains stable and functional, regression testing helps improve the overall user experience. This is important because a good user experience is key to the success of any mobile app.

How to Perform Regression Testing on a Mobile App

Performing regression testing on a mobile app involves a series of steps. Here’s a step-by-step guide on how to perform regression testing on a mobile app:

Step 1: Determine the scope of the regression testing. This involves identifying which parts of the app need to be tested and which areas are most likely to be affected by any updates or changes.

Step 2: Create a test plan. This should include a list of test cases that need to be run, the expected results, and any tools or software needed for testing.

Step 3: Run the test cases. This involves executing the test cases and recording the results.

Step 4: Analyze the results. This involves reviewing the results of the test cases and identifying any bugs or issues that need to be fixed.

Step 5: Fix any bugs or issues. This involves working with the development team to fix any bugs or issues that were identified during testing.

Step 6: Re-run the test cases. This involves re-running the test cases to ensure that the fixes have resolved the issues.

Step 7: Report the results. This involves documenting the results of the testing and reporting them to the development team.


Regression testing is a critical component of mobile app development. It ensures that an app remains stable and functional even after multiple updates and releases. By identifying bugs and issues early on in the development process, regression testing can help reduce overall development costs and improve the overall user experience.

By following the step-by-step guide outlined in this article, you can perform effective regression testing on your mobile app and ensure that it provides a seamless user experience to all users.
