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 client requirements or specifications. There are many instances when minor flaws in software have resulted in both human and monetary loss. That is why; software testing has already become 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 the programmers and testers working as a single team and working together to improve the software’s quality. As an integral part of SDLC, the software testing process aims to assess the software’s completeness, correctness, and quality before its delivery. Simultaneously, the test results help businesses check if the software meets all requirements or specifications of the client.
Why is Software Testing Important for Modern Businesses?
Several 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 the 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 companies must perform various tests to identify and eliminate all defects, bugs, or flaws in the application before it is delivered to the client.
Each modern user has the 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 assessed 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 a 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 the testing environment and production environment are identical, the software’s performance 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.
Modern websites and web applications must be compatible with multiple operating systems, devices, and web browsers. So the enterprises must assess the web application’s performance on various devices, platforms, and browsers. The seasoned testers use advanced tools to assess the website’s compatibility across multiple platforms and devices. The test results further help developers make changes to the code to enhance their compatibility and accessibility.
Many businesses deploy independent QA professionals to protect their goodwill in the competitive market. The online forums and social networks have made it easier for modern users to highlight the defects or flaws in a particular software application. So the enterprise needs to ensure that the end-user detects no bugs or flaws. When the software is tested thoroughly, the chances of bugs detected by users are eliminated. Thus, software testing will help developers impress users and stay in business for a longer time.
With more and more businesses adopting agile development methodologies, software development and testing have become inseparable. Each business has to invest in comprehensive software testing to get higher returns, enhance its reputation, and retain clients.
