HOW DOES SOFTWARE TESTING ENSURE HIGH-QUALITY DEVELOPMENT?
Let’s say you find an ideal development team that creates the perfect app you order. How do you know it’s not just a pretty picture, but a perfect piece of engineering software that will give you a good profit? That is why the practice of quality control, including software testing, were created.
Quality control is an integral part of the software development process, focused on fulfilling quality requirements. The purpose of quality control is to find flaws and defects in software products and to eliminate them before the final release. Testing is one of the most important measures of quality control software. And as a customer, you have to understand, how the testing guarantees perfect quality of your product.
Today most of the software development company employing Agile development to produce new applications quickly and cost effectively. In agile methods, software testing is integrated into the development process, the developers and testers often compare notes and think beyond their designated roles to ensure high quality products.
So how exactly do software testing work? Let’s take a peek behind the scenes of the testing procedures of Agile development processes.
STEP FOUR TESTING
Although testing is a continuous practice during the development process, can be divided into four important steps. We’ll go through them one by one for you to understand how software testing works.
The initial analysis of Quality Requirements
Before starting construction, you will have a very important meeting with your project manager and Quality Assurance (QA) specialists. Each of the parties concerned must be 100% aware of the needs of the product so that no problems will arise after construction is completed. initial requirements analysis will allow QA specialists to form the initial test plan, including the test specification.

ISO 9126 software quality characteristics split into six categories. To meet all requirements of the standard, the software developed to be functional, reliable, use, efficient, maintained and portable. Each of these requirements must be tested. You should be able to check the test results through a clear and concise documentation.
Testing in Iteration
agile development desired product split into a number of iterations. Intermediate results of each iteration is a version of a product with reduced functionality. This approach allows you to introduce changes to the product requirements and received the results of a rapid transition every step of the way. As mentioned earlier, Agile development tools, parallel development and testing process.

Therefore, testing is done in each iteration to correct any problems and does not transfer to the next iteration.
First, QA specialists to plan the testing process as a whole and determine its specific: types of testing required and software environment, the features to be tested and the testing criteria for each feature. Next, test documentation is created. This can take the form of a checklist or test cases, depending on the scope of the project and needs.

Once the initial phase is completed, the actual testing can begin. According to the plan iterations, the examiner checks to find any defects or problems. When the bug is fixed, it’s time for regression testing. It checks the quality of correction implemented and determine their negative effects on other components of the application. iteration is complete after the test results are analyzed, and the test report is compiled.
End Testing and Verification Before Release
When the developer is finished, it is time for testers to roll up their sleeves and get down to work. In the final stage, you will not be able to change your needs lots. All you have to do is wait for the testing to be completed before the final release of your software.

Testers working full-time on checking and re-checking code, finding and fixing bugs and polishing the finished product. This step is very important and never miss because only now testers get their hands on the entire functionality of the product and can test the final version. Do not try to rush testing together, as a sloppy quality control can lead to a number of problems of post-release.
Post-Release Maintenance and Support
In a world that is always changing, no application can last forever without any updates. Each new version needs to be tested with the same attention to detail as the first release. And even if you do not plan to launch an upgraded version in the near future, it’s a good idea to invest in some post-release maintenance. There must have been some unexpected problems that require instant fix. quality control and quality assurance measures are as important post-release, because they are before the final launch.

PEOPLE BEHIND TESTING
Testing is typically assigned to a separate part of the team to ensure that each test is completed to compliance with quality assurance standards, strategies, and guidelines. Dedicated professionals have the experience and methodological skills required to plan, analyze and perform all kinds of necessary testing. Testers continue to improve methodologies and their tools to meet varied demands of the market and to optimize existing techniques.

Most of the tests (about 80%) is automatic. They require regular results with various repetitions in one or more iterations. test load and other types of tests that are difficult to do manually is also automatic. The test requires environmental testing and specialized software to ensure solid results. The remaining 20% of the tests carried out manually to assess the utility of the product, accessibility, and other characteristics.
Now you know how the testing helps ensure the high quality of your software. But remember that testing is only one of the reactive part of the management of quality control and quality assurance system. There are many proactive measures focused on ensuring confidence that your quality expectations will be met. But that’s a story for another time.
