What is the importance of Regression Testing in Agile Methodology for Software?
Software Testing involves many complex techniques and methodologies before a smooth delivery to clients. The best Application Development approach is the Agile Method and it involves Regression Testing for software.
Agile method is used widely for software testingservices due to its many advantages over other project development methods.
Agile methodology increases the visibility at an early stage of the project development life-cycle thereby decreasing the Project risks. Regression checks the stability of the system after new additions to it. So, the importance of regression testing in agile methodology for software development grows manifold.
What is Regression Testing?
It is one of the most widely used software testing technique. Usually, developers while fixing a bug or an error write and publish new code within the existing functionality.
Sometimes the code affects that functionality adversely. The Regression Tests provide accurate information and reports to confirm is the new code has altered the functionalities in any way.
What is an Agile Software Development Methodology?
Agile helps with performance testing with its unique benefits in software development and testing life-cycle. It is based on iterative and interactive sprints to evolve a great software product.
In other words, the Agile development process is divided into parts called sprints. With each incremental sprint in SDLC, it revisits the previously developed sprints that recognize the improvements or hidden requirements and adapt them in the next sprints.
In this manner, Agile testing allows the developer to continuously develop iterative sprints to improve the undiscovered bugs in the next sprint.
Performing regression testing in agile methodology confirms that the newly developed sprint does not affect the existing code or business functionality adversely.
Since, Regression test selection focuses on the effects due to new development and Agile Methodology is the concept of iterative development, it makes sense to use Regression testing and Agile Method to serve incremental and iterative development of business applications.
What are the benefits of performing Regression Testing in Agile Software Development?
As Regression testing complements Agile Software Development method, there are many tangible benefits for developers and clients like:
Finding a defect at an early stage of software development life cycle can prevent from excessive rework hence developing the product on time.
Continuous testing helps in the overall quality and stability of the software.
It decreases the probability of missing the hidden requirements by uncovering them while early testing.
Identifying the defects and eliminating them earlier in the software development life cycle gives a foresight of the entire system.
Improves overall user experience for the developed software.
Regression testing is a time consuming and a repetitive process, so it is advisable to use the automated regression testing script for performance tuning and assessment of the existing software.
Moreover, it allows developers to increase the test coverage in a short time.
In regression testing, test cases call regression test suite once requirements for functional testing are finalized. Users must update the suite of there are any changes with the requirement or test scenarios within the software of functionality.
The process of updating the regression test is long but it helps in achieving all the goals to stabilize the software.
It is recommended to use the regression testing automation by trained quality employees who understand the whole process and keep the user/ client expectations at the center.
The whole testing exercise with regression is to find maximum defects within the software and agile makes it easy and comprehensive to use delivering a high-quality software.
