Users demand a consistent experience from the application across all versions, regardless of what operating system or browser is used to access them. They also expect that if a feature works once, it will always work.
Regressing is a type of testing that guarantees everything that was functioning properly before the changes in the code continue to function correctly after the changes. Additionally, it makes sure that an application’s new improvements maintain its already functional features and usefulness across many platforms.
But regression testing demands a detailed analysis. While performing regression testing manually is an option, automated testing solutions can complete the task more rapidly. After every change to the applications, automated regression testing tools run the tests again to make sure that no functionality has been broken. They can increase productivity, optimize processes, cut expenses, and accelerate the development process.
There are several regression testing tools available right now, anyone trying to integrate them into their application is likely to become confused. Additionally, if the incorrect one is chosen, the situation will worsen. To prevent this from happening this article includes a brief overview of some of the top current regression testing tools for Web and Mobile Apps. This will enable choosing a tool that best complements the team and the practices.
Let’s first learn more about regression testing, its advantages, the reasons for its necessity, and finally the selection criteria for choosing the best regression test tool, before moving on to regression testing tools.
Regression Testing
Regression testing involves rerunning all functional and non-functional tests on a modified version of an application that has already been tested to find any bugs that were hidden or made obvious by the modifications. This implies making sure that a new build or change won’t impair functionality that was previously functional.
Regression tests are crucial to ensuring that the application continues to function as intended. It aims to find new flaws in functionality, while new feature testing concentrates on confirming the functionality of new code.
Regression testing, to put it simply, is a process where testers run test cases on an application that has the newest code and check to see if it is compatible with the older, stable codebase. It includes checking for performance problems, new features, and UI modifications.
What Are Regression Testing Tools?
Automated Regression tests are performed using tools to ensure that updates to an application have not resulted in any new bugs or issues that were not present in earlier versions. Tools for regression testing automate the laborious and time-consuming process of running previously run test cases to make sure the application continues to function as intended even after changes introduce fresh changes.
To find any changes or problems that may have been introduced, these tools can compare the findings of the most recent test run with the results of the previous test run. They are essential for having an efficient and accurate process in place to identify bugs and problems as soon as they arise.
Regression testing: Why it’s Important
Regression testing offers a variety of advantages. A few of them include
- Reducing the possibility that modifications to the codebase will damage the functionality that is already in place.
- Check to see if the previously functioning functionalities have any issues caused by the new code.
- Helps to identify different problems before they become difficult to uncover and cause trouble for users. This ultimately saves time and hassle and boosts people’s confidence in new releases.
- Increases application quality by making sure that new features can be added more quickly and with less time spent on troubleshooting.
Regression testing tool selection criterion
Here are some of the most crucial factors to take into account while choosing the most effective regression automation test tool.
User Experience
When choosing a regression testing tool, the user interface (UI) is crucial to take into account because it influences how simple and effective testing activities may be completed. A UI that is badly designed can cause dissatisfaction, failures, and decreased productivity. While a well-designed user interface (UI) makes it easy for testers to swiftly navigate the tool, comprehend its functionality, and easily generate and run test cases.
Usability
Usability should also be taken into account because it has a direct impact on the effectiveness and efficiency of the testing process. Regression testing can be carried out more thoroughly and accurately if testers have access to an intuitive and user-friendly tool that makes it simple for them to build, run, and analyze test cases. On the other hand, a tool that is challenging to use or demands extensive training, might waste time and resources and even lead to mistakes during testing.
Integrations
The ability of a regression testing tool to support continuous integration and continuous deployment is another crucial requirement. Software integrations are necessary to assess how well the tool works with other systems and tools in the testing environment. Testers may quickly interchange data and information from the same platform using integration features, which also improve workflows and lessen the chance of errors or inconsistencies.
Quick and simple scriptwriting
As more features are added, the number of regression tests grows significantly, reaching thousands. A regression testing tool that facilitates script creation is typically a viable option for this.
Regression testing tools for Web and Mobile Apps
When programming is done on existing code for corrections, updates, or improvement purposes, the test team must have a robust regression testing process. This is done to check the functionality and stability of both the updated and original code. This process can be managed with the aid of regression testing tools, which can track issues and set priorities for solutions. The top tools for web and mobile app regression testing are listed below.
