Step By Step Regression Testing in Mobile App Development

News & Blog

Mobile app development is rapidly becoming more complex and time-consuming. Developers are constantly searching for ways to make their apps more reliable and secure. One of the best ways to ensure quality is by performing regression testing.

Regression testing is a technique used to verify that changes made in one version of an application don’t impact existing features or functionality of earlier versions. It helps to identify bugs that may have been introduced during the development process and can help to reduce the risk of unexpected errors and crashes. Most developers implement these techniques to ensure that their apps are bug-free and ready for production.

Step-by-Step Guide to Regression Testing

The key to successful regression testing is to create a test plan that will thoroughly cover all features, functions, and scenarios of the app. Below are the basic steps of regression testing for mobile apps.

As you gain experience, you may want to add additional tests to your test plan or change how you execute them. It’s important to be diligent in your approach, as regression testing is one of the best ways to ensure that your app is ready for production.

1. Set Up the Environment

First, you must establish an environment where you can perform regression tests. This could be a physical device or an emulator. Depending on your development environment, you may need to install the app on multiple devices or emulators to test it properly.

2. Select Test Scenarios

Next, select scenarios that will effectively cover every feature and functionality of your app. This includes selecting tests that exercise UI elements, navigation paths, as well as any back-end services connected to the app. It’s important to cover all possible scenarios, as any bugs in these areas could cause serious issues with your app.

3. Execute Tests

Once the test environment is set up and the scenarios have been identified, you can execute the tests. This involves running each scenario manually or automatically to ensure that everything works as expected. Depending on the complexity of the app, this could take anywhere from a few minutes to several hours.

4. Record Results

As you execute each test, it’s important to record the results to compare them against previous tests. This will help you identify any bugs that may have been introduced and document how they were resolved.

5. Analyze the Results

Once all tests have been completed, it’s time to analyze the results. This involves verifying that each test passed and that no new bugs were introduced. If any issues are found, they must be addressed before moving on to the next step.

6. Create a Report

Create a report of the tests that were executed and the results. This will help you track progress and document any issues that need to be addressed. The report will also serve as a reference for future regression testing.

7. Monitor Post-Release

Finally, after the app has been released, monitor reports from users and ensure that all bugs have been addressed. This is especially important for apps that receive frequent updates and feature changes. It also contributes to the continuous monitoring of your mobile app’s security. Monitoring reports will help you identify potential performance issues or other problems users may be experiencing, so you can quickly find a solution.

Additional Tips for Implementing Regression Testing in Mobile Apps

Many technicalities come with regression testing, so developers must always be prepared and have the necessary resources to conduct such tests. To be effective, developers must consider regression testing throughout the development cycle. This means running tests at each stage of the development process.

Additionally, effective regression testing requires attention not only to the software development process but also to the hardware infrastructure, including proper cable management, to ensure that mobile app features are rigorously tested and bug-free. Here are some more tips to make regression testing effective in your mobile app development process:

Run automated regression tests.

Automated tests are often more reliable than manual testing and can save time by quickly testing multiple conditions. Automated regression tests should be run after any code changes, bug fixes, or updates to ensure that existing functionality has not been affected.

Address bugs as soon as possible.

As with any software development process, it’s essential to address any bugs or issues that arise as soon as possible. This will help reduce the time spent on regression testing and limit any changes’ impact on existing features. This is especially important if your app deals with fintech, such as mobile payment options or banking because any bugs or glitches could cause serious concerns for users.

Implement a QA process.

It’s important to implement a Quality Assurance (QA) process to ensure that changes made to the codebase are thoroughly tested. A comprehensive QA process can help you identify any hidden bugs or issues and save time by finding them earlier in the development process.

Keep your regression tests updated.

As your app evolves, make sure to update your regression tests accordingly. This will help you ensure that changes made to the app don’t affect existing features and functions, and keep your app up to date with the latest technology.

Final Word

Regression testing is essential for ensuring that mobile apps are bug-free and perform as expected. By following the tips outlined above, you can ensure your regression tests are effective and help ensure a successful launch of your app. Taking the time to properly test your app before releasing it can save you from costly mistakes down the road and is also key to staying ahead of the curve.
