Why is Software Testing Important? [7 Core Reasons]

Key Takeaways:

If you want to know why is software testing important, here are the three core reasons.

  • Software testing helps identify and rectify bugs and errors in the software, ensuring optimal performance, usability, and quality throughout the development process.
  • Testing your software under various conditions and environments ensures its efficiency and compatibility, which ultimately builds customer trust and improves your brand reputation.
  • Integrating software testing within the development phase enhances the overall quality of your product, reduces costs, and ensures better security, functionality, and customer satisfaction.

When developing a software application, you want it to function well, provide a good user experience, and prevent any data breaches.

But, how do you ensure the security, performance, and usability of your software?

The answer lies in robust software testing, a process that’s integral to software development. However, it’s not enough to conduct arbitrary or random tests.

To make the testing process thorough and effective, you need to follow a structured approach for testing that is STLC. By following the software test lifecycle, you can deliver error-free solutions. If you want to learn in detail about each step, read this guide on phases of the software testing life cycle.

Now, you might wonder what happens when you don’t perform software testing. Why is software testing important before releasing your software to end users?

In this blog post, you get the answer to your question. We have written 7 key reasons for the software testing importance and why it is an important part of the software development life cycle.

By knowing these reasons, you will learn about the core areas where testing is important and how it significantly helps to develop high-quality software applications and gain the trust of your end-users.

7 Core Reasons for the Importance of Software Testing

Let’s start with the first reason which is identifying the bugs and errors within your software.

  1. Rectifies the Bugs and Errors of Your Software

    Conducting testing during the entire software development life cycle helps software testers to rectify the hidden or missed bugs that could be potential threats. Bugs could be regarding performance issues, functionalities issues, security issues, or usability problems for the end-users.

    This is why incorporating testing at an early stage helps to identify the bugs and errors during the development stage only. This results in faster test feedback and development of your software by maintaining its quality, performance, and usability.

  2. Ensure the Performance of Your Software is Efficient in Every Condition

    When you develop software, you want to ensure that it performs well in most conditions:

    • Works on different environments (Cross-platform compatibility)
    • Handles a sudden high user loads
    • Performs under different network conditions (Network latency and connectivity)
    • Adopts different languages, currencies, time zones, and regional settings
    • Ability to recover from software failures or crashes or database corruption

    Testing your software in real-time environments and conditions helps you to resolve potential issues before your software reaches your end users. Delivering robust and reliable software products to your end-users helps you to gain trust and build a brand reputation.

  3. Reduces Costs of Your Software Application

    Generally, the cost of fixing the issues and bugs of your software increases as it moves from development to testing, and deployment in the production environment.

    The reason is when your software becomes more complex, the testing becomes more time-consuming. Thus, it becomes more costly to fix the bugs of software at the later stage of development.

    This is why early detection and resolution of your software bugs or fixes are and also become a cost-effective option.

    To know more about testing, you can read our brief explanation of software testing.

    Software testing helps to identify bugs related to issues:

    • Code quality
    • Architecture
    • Maintainability
    • Performance
    • Security

    Moreover, early detection of your software bugs helps you to avoid post-release issues which might be costlier than testing your software afterwards.

  4. Ensures the Security of Your Software

    Protecting the data of your customers is important to build trust in your software. If your software has potential vulnerabilities and weaknesses, there are chances of exploitation by any hacking groups. In such a case, security testing is helpful to validate input, authentication, authorization, and applying encryption to secure data.

    In addition to that, during testing, properly managing the patches and updates ensures that vulnerabilities of your software are addressed and reduces the chances of attacks on your software.

    Automated tools like Test Sigma, Selenium, Cucumber, and LamdbaTest are a few of the testing tools that help to perform proper software testing. So, there are no issues found after deployment.

  5. Validates Your Software Functionalities

    Performing end-to-end testing of your software application helps you to check if your software is aligned with your business goals. During quality assurance, it is necessary to check the functionalities and features of your software application.

    Testing the functionalities and features of your software product help you to know whether your software performs as per the original requirements. This way, you ensure your software meets your user’s needs and expectations.

    Let’s understand the above paragraph with a real-life example.

    For example, if you have created a bank application for your end users. The software product has different functionalities like checking account balances, transferring bank funds, paying bills, and viewing transaction history.

    Now, if any user clicks on any of these functionalities, they should get accurate and proper results. If a user clicks on check account balance, then they should know their account balance. However, view account balance functionalities should work perfectly without any issues.

  6. Builds Customer’s Confidence and Trust in Your Software

    Your primary goal after launching your software is to build the trust of customers in your software application. But, if your software has several bugs and issues or provides a poor user experience, it becomes difficult to gain the confidence of customers in your software.

    This is where performing efficient testing helps. By following the software testing life cycle, you ensure that your software works perfectly fine and meets end-users’ expectations.

    As you earn the trust of your users and customers, they are likely to purchase your services and potential users are likely to end up being your customers. The first impression of your software is the last impression. So, ensure to provide the best quality software to your customers as they have put trust in your product and have paid their hard-earned money.

  7. Improves the Software Development Life Cycle

    When you incorporate manual testing or automated testing within your development phase, it helps you to enhance the overall quality of your software.

    Because software testers and developers collaborate to provide your high-quality software application that is according to your business requirements and performs well.

    The software testing process becomes simple as software testers would be parallelly finding the bugs in your application and the software development team would be fixing them in no time. So, thoroughly tested software helps you gain the trust of your customers.
