Following are the 10 reasons why software testing is important -
Better Software Quality: Software testing is important because it helps ensure the quality of the software.
Testing helps identify defects, errors, and bugs and errors that can impact the performance and user experience of the software.
Better User Experience: Testing helps ensure that the software is easy to use and meets the needs of its intended users. This helps enhance the user experience and can lead to greater user satisfaction and adoption.
There is a dedicated section in quality assurance that pays attention to ensuring enhanced UI and UX.
Cost Reduction: Early identification of defects in the development cycle, testing can help reduce the cost of fixing defects later in the cycle or after the software has been released.
There have been cases when the bugs released to production have caused tens of millions of dollars in losses to the companies. It's better to catch bugs in the development stage.
Enhanced Reliability: Testing helps ensure that the software is reliable and performs as expected under a variety of conditions.
This can help build trust in the software and increase its adoption.
Ensures compliance: Testing can help ensure that the software complies with industry and regulatory standards, such as security and privacy regulations.
The software testing process begins at the time of requirements gathering stage of the SDLC. This makes sure that developers are aware of what the customer expectations are; and can develop the software accordingly.
The software QA teams can write proper test plan to aim for 100% compliance.
Increases efficiency: Testing can help identify areas of the software that can be optimised or automated, which can lead to greater efficiency and productivity.
Enhances security: Testing helps identify security vulnerabilities and weaknesses in the software, which can be addressed before the software is released and deployed.
For mission critical software, security needs to tested for. Imagine launching a rocket without properly tested software - it's bound to fail.
Enables continuous improvement: Testing is an ongoing process that can help identify areas for improvement in the software, leading to continuous improvement over time.
Helps with risk management: Testing can help identify potential risks and issues with the software, which can be addressed before they become major problems.
Enhances reputation: High-quality software that has been thoroughly tested can enhance the reputation of the software developer, company and corporation and increase customer loyalty and retention.
Note that every software needs to be thoroughly tested before it's released.
