Agile software development illustrates a suite of principles for software development, which leads requirements and solutions that evolve by way of collaborative efforts of cross-functional teams. Agile architecture recommends flexible planning, evolutionary development, delivery before time, and continuous improvement.
The application of test automation often leads to budget and schedule overruns and branch of from test objectives, which should be complemented by this application. The reason for this is that test automation is a kind of software development but it is seldom treated so. Therefore, by applying certain best practices in software development, particularly agile principles to test automation, you can bank on a reliable and maintainable solution in line with your testing as well as business objectives.
Benefits of implementing agile principles to test automation include enhanced client involvement and visibility, scope management, budget and schedule control. There are several strategies for matching agile processes, artefacts, and tools for testing automation development jobs.
Client Involvement, Changing Requirements, and Incremental Development
With agile techniques, there is better stakeholder visibility and expectation management. Customer input happens all through the development process and emphasis is given on their feedback. The inputs usually come at the beginning during requirement gathering and sometimes nearly at the end of the project. The customer might have had some requirements to start with, but after a few months, he changes his mind and hence there are changes in requirements too. You are obliged to develop the project in agreement with customer’s changed requirements. Even so, after a couple of months, there are further changes. Agile methodologies welcome changing requirements, even late during the development, but in small increments. The delivery is done in small iterations and if customer wants some changes, they can be done in the next iteration (7 to 15 days away) from that iteration. As soon as a feature is developed, it is tested and demonstrated and thus the chances of deviating from the track are pretty slim.
With agile practices, generating data for other test objectives becomes easy, executing smoke test or build verification test takes lesser time, and there’s better support for automation. Focus is given on delivering working software frequently, with minimum time span. The deployment of iterative planning and feedback in teams can continually side with delivered products that reflect clients’ expectations. A product might not be precisely as per the client’s expectation, but it’ll be delivered on time. As soon as the client provides feedback, the product that the customer envisioned will be achieved.
There’s improved scope management with improved and shorter feedback frequently. The improvement architecture level begins by defining the goal, scope, and context, resulting in an improved approach. A continuous process where improvement against desired result is checked constantly will result in continuous improvement. Also, transparency in any modifications done in scope management can be maintained.
Because of these advantages, the software developers have changed their methodology from the conventional “Waterfall (Sequential, non-iterative design process, used in software development)” to the effective “Agile methodology (Incremental, iterative work sequences, and called sprints).”
