A flawed software application can have a huge impact on the developer’s revenue, credibility and reputation in the longer run. So before delivering the software to the client, each company needs to ensure that it is working flawlessly and meeting all requirements or specification of the client. There are many instances when minor flaws in software have resulted in both human and monetary loss. That is why; software testing has already becomes an integral and significant part of the software development life cycle (SDLC).
The agile software development principles further do not consider software development and software testing as two separate processes. The agile methodology emphasizes on the programmers and testers working as a single team, and work together to improve the quality of the software. As an integral part of SDLC, software testing process aims to assess the completeness, correctness and quality of the software before its delivery. At the same time, the test results help businesses to check if the software meets all requirements or specifications of the client.
Why Software Testing is Important for Modern Businesses?
A number of studies have indicated that the cost of fixing bugs in the software increases, if they are not identified and fixed early. When the defects or bugs in the software are detected early, it becomes easier for programmers to eliminate them. That is why; most companies nowadays introduce testing in early phases of SDLC. They further deploy independent QA professionals to assess the software during various stages of development.
Nowadays, IT companies to develop custom and mission-critical software applications. A minor bug in the mission-critical software application can result in both financial and human losses. For instance, a minor flaw in the software used by an aircraft can result in irreparable losses. That is why; the IT company must perform a variety of tests to identify and eliminate all defects, bugs or flaws in the application before it is delivered to the client.
Each modern user has option to choose from thousands of identical software applications. So to keep the users interested and engaged, each enterprise must deliver high quality software. When the software is tested thoroughly and repeatedly, its quality can be assesses more effectively. Based on the test result, the company can launch a high quality product that will stay in the market in the longer run.
Software testing further becomes essential for businesses due to the differences between the development and production environments. While developing the product, programmers focus mainly on its features and functionality. But the features and functionality will have different effect on individual users. When the application is assessed in the testing environment, it becomes easier for QA professionals to assess the user experience accurately. As testing environment and production environment are identical, the performance of the software can be assessed more accurately.
Often clients require developers to include new features in the software during different phases of development. Each time a new feature or functionality is added to the application, the code needs to be tested thoroughly. The QA professionals perform regression testing to ensure that both legacy and new features are working flawlessly. The tests will further help the business to assess the quality of the updated product before it goes live.
