A Closer Look at The Curious Case
The traditional testing way is not the best choice anymore, because it is time-consuming, and we all know – time is money. Many IT companies try to keep up by applying Agile software development and testing methodology. Immediately after presenting, Agile approach became an integral part of every business that wanted to increase their success and profitability. The Agile approach focuses on quick delivery, constant feedback, and customer service. But, it is also very challenging to implement it with complete success. What is Agile testing (by software testing definition), how it works and what its principles are – learn in this article.
What Is Agile Approach by Software Testing Definition?
Agile testing is by software testing definition a practice that leans on fundamentals of Agile software development. Agile testing means testing software from errors or performance issues inside the context of a flexible workflow. The word agile itself means characterized by quickness, lightness, and ease of movement. Precisely this agility and fast responding to changes are essential features of Agile testing. In Agile development, software developing goes in cumulative, rapid cycles. So, testing goes the same way. When testing in cycles, the result is releasing small incremental part of the product, where each release continues one to another and its functionalities. It is important to ensure software quality in each release, so testing becomes a vital part of every development process phase. When Agile approach starts to implement well, it will provide greater efficiency and release of the creative potential of software production team.
It’s All About the Communication
Developers and testers need to collaborate closely in Agile approach. By software testing definition, developers are code creators and testers code breakers, but actually, they are two sides of the same coin. Here in Agile approach, developers need to think more like testers, regularly checking their code for possible errors. Testers need to think more like developers, softening their destructiveness and participate more in the creative process. Here is the core of Agile software development methodology – to build a great team of development and tester thinking, with the same vision of software product. This team, except developers and testers, also includes managers and customers. Everyone needs to work together closely. Constant feedback from every member of this team is important because everybody has their vision of the final product.
If the team is working closely together, it will lead not only to better communication with clients and each other but better and faster reaction when it comes to changing project requirements. The goal for the whole team needs to be the same – to deliver flawless product to the market that will satisfy all of the customer’s requirements.
How it Works – the Iteration Cycle
In the Agile approach, software development goes incrementally in the phases called iterations. Every iteration should last equally – between two to eight weeks, and every phase should deliver a working product. The team that works on software development will decide at the beginning which features are essential that they will develop in the first iteration. If developers can not realize some planned features, they will take place in the next iteration or subsequent iterations, depending on priority. Generally, in each project will be ten iterations. At the end of every iteration, the customer will receive updated working software with the features planned for that iteration.
This approach to software developing is great because it provides constant interact with clients. When each iteration finishes, the customer can send his feedback, so if he requires some changes, it will be possible and easy to implement it.
Today, it is essential to understand how Agile testing is working and that it is crucial to apply it in your company’s daily routine. It is different from any other traditional form of software development and testing. While traditional way separates jobs and functions, and maintain exact order in software development, Agile software development considers some feature done only after completing all of the phases: design, development, testing and rework.
Principles of Agile Testing
Agile testing aspires to unite teams around several principles – collaboration, simplicity, transparency, flexibility, and responsiveness to feedback. Every company that decides to implement Agile testing needs to understand its principles deeply:
Testing moves the project forward
By Agile software testing definition, a product in emerging needs to be error-free from the beginning. This testing provides feedback on an ongoing basis. While software development lasts, the product is in constant checking phase, to see if it meets business requirements. Testers and developers need to collaborate well, not be on opposite sides.
Testing is not a Phase
Testing is a continuous process, not a phase. If testing continuously, you will be sure that features implemented during a particular phase of development are done. That is the only way to ensure constant progress in software developing process.
Testing is everybody’s responsibility. Testers, but also developers execute tests. It is not like in traditional software testing definition, that testers are the only ones who are in charge for testing activities. The whole team needs to collaborate. Every iteration of software development needs checking. If checking is left out, it means that team cannot do as much as they planned to. That is the indicator of mismatch between testers and developers. Sometimes developers progress too quickly and leave no time and space for testing. But, they need to realize if the testing phase is not done, product and its features are not ready for releasing, so their job is not done either. Deal with it – everybody test.
Shortening Feedback Loops
In traditional software development, time in which developer waited for feedback about his code behavior was too long, and then a feedback loop was created. These loops can last for a long time if the software product goes under test only at the very end of development phase. But, decreasing loops with Agile testing implementation is possible. In Agile approach, testing runs from the beginning of the software development and testers check product on several levels.
Automated tests check the behavior of individual functions and object interactions. They run on ongoing base, provide fast feedback and check system thoroughly. Manual testing requires more time to execute, and feedback comes too slowly. Manual testing depends on humans, so it may not begin immediately, and even when it starts, it can be prolonged to days, weeks or months. Although manual testing is not worthless, Agile testing appreciates more that feedback loop is shortened as much as possible, so that risk and rework are cut down.
Keep the Code Clean
Agile developers and testers have their routine that is pretty strict. Their code is clean because they are disciplined. As soon as they found some bug, they need to fix it. It is a great approach, because if removing bug is delayed, it will be only hard to find and fix it later, and the result may not be satisfying.
Because of daily meetings and collaborations with the team, there is no comprehensive test documentation. Even when it is necessary, Agile approach suggests reusable checklists and using lightweight documentation tools. It records ideas in charts, focusing on the essence of the testing. Agile testing use one test artifact both for manual and automation testing. One manual test can become automated when the developers connect the test to the software.
Implementing and testing
Developers need to understand that they will finish some feature only when testing is done. The story is not finished only by implementing. Agile teams count on both of processes before releasing the software product.
The traditional approach to testing derived tests from requirements documentation. So, testing comes second, at the end of the project. In an Agile way, testing lasts from the beginning to an end and gives an example what means when software meets its requirements. That helps in creating and accomplishing a common goal for all the Agile team.
Software development and testing progress every day. When the traditional way of software production was replaced by new, modern and better one – by the Agile approach, that was a big reversal. Agile methodology brings collaboration inside the team and with customers, ensuring better respond to the changes and delivers working software in every iteration of the project. It represents a departure from traditional approaches and traditional software testing definition. All IT companies seek for effective, time and money saving way to streamline processes of developing software project. Agile approach steps out and becomes number one in managing software developing and testing projects.
