Reasons Why Software Testing is Important

In the present-day world, billions of software are in usage to accomplish several tasks simultaneously. But unsurprisingly, we end up making mistakes of which some are negligible, and some have detrimental effects. In software development projects, errors can appear in any of the stages of development; some of them even remain undiscovered.

When any software is created, it has to go through a number of test cases to confirm whether its target operations function as planned. By definition, Software testing is a procedure to find defects within a software system and to ensure it is bug-free when it is ready for usage.

Software testing is a process of checking software applications and products for bugs/errors (and fix them) to ensure performance is efficient. It involves the execution of software/system components using manual or automated tools to evaluate one or more properties of interest. Testing in software engineering is a fundamental process of creating reliable — and usable — software products.

A software bug is an error, flaw or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.

So, in software development to identify errors/problems before they occur is crucial. When designing a software product, it’s important to check everything because things can go wrong. Here are the reasons why Software Testing is really important:

Saving Money

It is always harder and more expensive to correct a mistake than to prevent it. Software development consists of many stages, and if errors are not detected in the earlier stages, it will be much harder to fix them.

Clients always demand bug-free software products, and thus, software testing is unavoidable in the Software Development Life Cycle (SDLC). Software testing helps to make sure that the product functions properly and serves the intended purpose.

The iterative approach of the Agile model perfectly fits in the well-known concept of testers “test as soon as possible and even more often.” Indeed, every critical stage of software development ideally should end with testing.

Customer Satisfaction

The effectiveness of any software is valued through customer satisfaction. The real test that software’s created for the people undergo is that of consumer usage and how it has adequately fit into their daily lives and so software and apps should be tested to bring the best user experience.

Owning the best software product in the market will help you gain loyal clients which will have significant long-term effects. If users of your software have great customer experience, they will tell their friends and word to mouth is the best way of marketing.

Also, in marketing as of recently, the first impression is important; otherwise, users will find another product that meets their needs.


To shed some light on the importance of software security, In May of 1996, a software bug caused the bank accounts of 823 customers of a central U.S. bank to be credited 920 million U.S. dollars. Like this situation, most hackers use some of the bugs to target software products. That is the reason people are looking for trusted software products that they can rely on.

Companies must assure top-notch quality products to customers and be more careful with their users’ data because of personal information and what we do with it should stay as private as possible.

How testing can help your product security

  • The user gets a trustworthy product;
  • Keeps user’s personal information and data protected;
  • Problems and risks are eliminated beforehand;
  • Saves a lot of troubles later on;

Product Quality

Products always serve users in some ways, so releasing quality products with a lot of bugs will surely not satisfy the users working with it.

To ascertain that your software product brings the value it promises, it should work properly to ensure a great customer experience.

Furthermore, due to the variety in the telecommunication company products, In case you are planning to launch an application, it is important to check its compatibility on different operating systems and devices.

Control Process

Software development processes should always be monitored, and you should measure whether it goes against the established requirements or not.

Behind every quality software product, there is a ton of work done, and it doesn’t matter what kind of software product you’re trying to create, software testing is the best way to verify each aspect of the software.

The best software application must be efficient and user-friendly that appeals to the customers.
