One of the most popular and fastest growing branches in the IT industry is software testing. The demand for engineers who work in the field of software testing is increasing, which is why the offer of jobs and trainings in that area is also on a high level.

But what is Software Testing and why is it so popular?

To understand software testing and its popularity, we first need to know what software quality is. According to the official definitions from ISTQB, and for better understanding it can be divided into two parts:

Quality: the degree to which a component, system or process meets the set criteria and user needs and expectations.

Software quality: the overall functionalities and features of the software product that rely on its ability to satisfy the required or imposed needs.

What is Software Testing?

Software testing is a process of evaluating the functionality of software applications to find the so-called software bugs, i.e. irregularities. The testing process checks that the software meets the required functionalities and identifies any defects in the software and a quality product can be produced. It is essentially a system check to locate any errors, gaps or missing claims in the initial claims.


The process of evaluating parts of a product (not the final product) at a development stage to determine whether they meet the requirements needed at that stage.


The process of evaluating software during or at the end of the development process to determine whether it meets the set requirements of the business.

Why is Software Testing necessary?

It reduces costs

Testing has many benefits but one of the most important is cost effectiveness. Testing our projects can save us money in the long run. Software development consists of many stages and if the so-called bugs are discovered in time at an earlier stage, the cost to fix them will be significantly lower. In other words, some bugs can lead to financial losses for the software user.


This is one of the most sensitive and delicate parts of software testing. Users are always looking for products they trust and can rely on. It helps them to eliminate problems and risks ahead of time.

Product Quality

In order the vision of the product to come to life, it must perform as intended. It is important to follow the product claims because they help to achieve the final results.

Customer Satisfaction

The ultimate goal of any product is to satisfy the user. The software should be tested so that it can deliver the best experience for the consumer. Having the best product in a saturated market helps to gain customer trust and achieve great effects in the long run.

Check software compatibility

There are many devices, operating systems and browsers today and it is necessary that the software is compatible with all of them, so that it can deliver a positive experience to the users. If software functionality is affected by device changes, it may deliver a negative user experience.

To locate bugs

Software testing helps to get rid of bugs in the product before the product goes into the hands of the user. Testing will lead to better functioning of the product because hidden flaws will be discovered and solved. The end result will be an excellent functioning of the product before it goes into wider use.

Speed ​​up software development

​​Running software testing and development in parallel can speed up the development process and make it more efficient. It allows for quick bug fixes and makes the software version less error prone.

To avoid risks

The software to be implemented in companies must be free from serious risks. Any mistake can lead to vulnerability. Software errors can result in loss of information and poor communication. That is why it is necessary to make sure that the software works optimally to minimize the chances of data loss and privacy violation.

To optimize the business

Testing allows the final product to possess a higher level of quality before it goes into production. It also adds value to the company’s image and increases profitability as support costs are reduced. Ultimately, customer retention and good service become part of a company’s reputation.

Finally, finding bugs in software is a common phenomenon. Leaving them unresolved can cause enormous harm not only to the customer but also to their supplier. By reducing software errors, the user experience is improved and maintenance costs are reduced.

That is why Software Testing is necessary in every company. The earlier you start, the better results you will achieve. Do you also want to build a career in software testing? Then don’t miss our academy!
