7 Basic Reasons: Why Software Testing is Necessary

Software Testing

Software testing – it is a process of checking software applications/products for bugs and errors to ensure efficient performance – is pivotal to effective software development. It is essential to understand as to why the need for Quality Assurance in software development is so important.

The usability, ensuing to popularity of any software product is directly correlated to its quality. Software testers help with detecting any errors and mistakes that can affect the quality of your software before it reaches customers and causes them to lose confidence in your product. It makes sure that the end-product can perform the way it is expected to.

Below are 7 important reasons as to why software testing must be considered mandatory.

1. To gain customer confidence

Customer confidence

Software testing makes sure that the software is user-friendly and thus, leads to satisfaction of the customer. Testers carry out the testing while keeping customer requirements in mind and therefore, help in making software easy-to-use and reliable.

Hence, testing proves instrumental in increasing the customer’s confidence in the product.

2. To check software adaptability

Cross-platform Testing

There are many devices, operating systems and browsers available today and it is necessary for software to be compatible with all platforms in order to offer users a smooth user experience.

If the functionality of software is affected by the change of devices, it can count towards a negative user experience. Testing eliminates such errors in the performance while adding to the compatibility and adaptability of the software.

3. To identify errors


Software testing helps to rid products of errors before the product goes into the hands of a client. Testing will lead to better functioning of the product as hidden glitches will be exposed and fixed.

The end result is the software will be exceptional in performance before it goes on wider release.

4. To avoid extra costs

It is a common misconception that software testing costs a lot and testers break the software. Instead in reality, if you ignore testing, it can result in additional expenses where bugs or mistakes come to the surface later.

Testing alleviates the need for a constant cycle of upgrades and fixes, as software testers identify bugs and errors before problems can arise. This cost-effective approach leads to efficient software development.

5. To accelerate software development

Software testing and software development if run in parallel  can accelerate the software development process and make it more efficient.

It allows quick fixation of errors and makes the released version of the software far less error prone.

6. To avoid risks

Software that is meant for implementation throughout an organisation, must be free of serious risks. Any bugs, errors or loopholes can lead to vulnerability.

Errors in software can result in huge loss of information and communication breakdowns. Therefore, it is essential to make sure that the software works optimally to minimize the chances of data loss and privacy breaches.

7. To optimise business

Optimise business

Testing allows the end-product to achieve a higher quality standard before being made live.

It also adds to the company’s brand image as well as its profitability through reduced support costs. Ultimately, customer retention and service reliability become entrenched in the software provider’s reputation.


Finding bugs and errors in software is a common phenomenon. Leaving them unaddressed will cause serious harm to not only your client’s business but to the supplier’s reputation as well.

By making software as error free as possible, testing enhances the user-experience and cuts down maintenance costs as well. Software quality highly depends on its smooth performance.

Therefore, role of software testing is something that the developers ignore at their company’s peril. The earlier it is done and the more thoroughly it is performed the better it is for developers and users alike, leading to a win-win outcome.
