Cutthroat competition and customers’ expectation encourages businesses to build more powerful tools by enhancing or adding new features. Whether these changes are small or big, simple or complex, it affects the existing functionality as well and brings unexpected issues. Hence, it is important to test existing features of the application to ensure induction of new changes has not impacted them. This is called “Regression Testing”. Regression testing is indispensable to identify the underlying bugs and other technical flaws within the software program. In its simple terminology, Regression Testing refers to the retesting of the previous changes to a software program ensuring its optimum efficacy in the current operating environment. QA testers and web application testing professionals must understand the benefits of regression testing and use the same extensively.
Testing forms an important part of the application development process to confirm the apt software coding by the developers. It is a highly technical operation requiring an immense level of knowledge and experience in software and application development process.
Benefits of Regression Testing
Thanks to timely intervention by quality software testers, and use of high-quality testing tools like actiWate, QTP, Selenium, SilkTest, Rational Functional Tester and Watir that automatically test the software and prevent any further mess.
Considering the efforts and time, regression-testing tools are faster, prompter, safer and more accurate than manual software testing. That’s the reason why every software firm opts for regression testing tools of its each enhancement, patches, and configuration changes. It can save 80% in testing – which is far more difficult and cumbersome than an automated testing.
1) Increase More Test Coverage In Less Time:
Testing takes the considerable efforts and time to coverage entire software. However, regression testing executes the selected scenarios and ensures functionalities work smoothly. Moreover, data inputs or devices can be changed on every run.
2) Know the Problematic Bugs Earlier:
Regression testing lets a firm knows which bug is causing problems to application following the software changes. Engineers can easily modify or replace the application code with the apt value to remove the bugs.
3) High-quality Software:
Regression testing ensures system stability while enhancing the application continuously. It executes the same steps repeatedly and allows the team with shorter development cycles by ensuring the high-quality of software.
4) Increase Efficiency and Cost Effective:
Automation of regression test cases allows the firms to keep the cost low by minimizing the team and involvement of human interaction. At the same time, resources can focus on more strategic and important tasks.
5) Timely Intervention:
Regression testing gives the firm opportunities to identify the problematic area in the system, and replace the same with appropriate programs to enhance the processing of the app and offer efficacious solutions to the business. Regression testing helps create a suitable way to record GUI response as an automated input.
6) Software Upgrade:
Regression testing helps to keep the technology up-to-date. Also, it is a long-lasting and effective solution to keep the software for proper usage, and reusable. Such a software testing generates high ROI and is less time to consume since the entire testing is processed via automated software.
A recent survey by a leading IT giant revealed that around 1000 bugs and technical gnaws were found in 47 different areas. Without regression testing, the software’s functionality could have fallen into jeopardy.
Factors to Consider Before Conducting a Regression Testing
1) Skill and Expertise:
Skilled or experienced software personnel should conduct the regression testing. Without proper knowledge, a person handling the test could draw erroneous inferences from the result concealing the real picture of the operating environment. Subject Matter experts should be always entrusted with the responsibility of supervising such testing procedure.
2) Documenting Process:
Whether a firm is conducting regression testing for itself or any other company, the documentation process needs to be astute. New releases and updates should be rolled out from time to time for security purposes. All results relating to the testing should be recorded in a chronological manner for quality assessment purposes.
3) Updated System and Physical Infrastructure:
Regression testing should be done using the latest software coding practices under the guidance and supervision of an experienced subject matter expert with a proven track record in this field. The computer, hardware, wire, and other tools necessary for the test should be up to date and of high quality, or else it may not reflect the actual picture of the software result.
By careful implementation of the regression testing method, a firm can ensure that users won’t encounter any problems relating to the opening of a web page or using a particular app. Usually, the team leader and QC (Quality Control) analyst cross-examine every minute details preventing any future error or technical bug.
In a Nutshell
These are the nagging problems leading to browser crashes, and often dent the image of the developing firm. Utmost focus and dedication should be diverted towards regression testing to ensure that the upcoming software is up to date and ready with related patches before it is rolled out to the public.
