Why is the role of a software test engineer so important

Software testers are often given a bad rap for being negative and always finding things that are wrong with a product. However, it's actually the job of software testers to find problems in a product so that they can be fixed before they cause problems for users. Software testers also provide an extra layer of quality assurance in a project because they can test the code on different operating systems or browsers than what is available at the time of development or testing. The role of software testers has become increasingly important over time as projects grow larger and more complex, since there are so many different factors involved in creating an application today compared with even just 20 years ago when most software was built by one person working on their own laptop.


A software test engineer is proactive. They can predict issues before they happen, find bugs before the user does and even find potential bugs before the product is released. A good software test engineer will use their knowledge of testing to predict where problems may occur in the future and proactively fix those problems before they become real issues for your business or product.

Increased quality

Quality is a measure of how well a product meets the needs of the customer. A good test engineer can help to improve quality by making sure that any bugs and other problems are found before they reach customers.

Testing is a proactive way to find and fix problems before they are released into production. Automated testing can be used to prevent bugs from entering the system, while exploratory testing (testing without an automated tool) helps you explore your site or app in more depth, spotting things you might have missed with automated testing alone.

Stable product

A stable product is a product that is reliable and performs as expected. A stable product is predictable, which means that it doesn't have unexpected behaviour.

A stable product does what it says it will do: if you click on a button, the button does something; if you enter data into an input field, the input field shows the value of what you entered; if you put some text in a box and press "submit," then submit will happen.

Customer confidence

Customer confidence is a key factor in the success of a product. It's no wonder that customer satisfaction is often used as one of the most important metrics for measuring software quality.

Customer confidence can be built through several measures, including proper user documentation and clear language in your sales pitches, but there's another way to build customer trust: testing your product thoroughly before release.

When you test your product before release, you're helping to identify bugs that could undermine the quality of your work and cause problems for customers later on down the line. By catching these bugs during testing rather than after-the-fact, you'll be able to resolve them more quickly and ensure that they don't lead to complaints or lost revenue.

Scalability and software testing

  • Scalability is critical to the overall health of your business. If you have built a product that cannot scale, it will fall apart as soon as your customer base grows. You need to make sure that your software can grow with your customers and still work well even when it's servicing thousands or millions of users at once.
  • Software testing is not just about finding bugs; it's also about making sure that your software scales as intended so that it can handle large amounts of traffic without breaking down. This is one reason why many companies prefer hiring professional software testers who have experience working with scalable products in the past: they know how to make sure their products are able to accommodate more users than before without losing functionality or stability along the way.


To give you some perspective on the costs of not testing and why it’s so important to ensure that software testing is done right, here are a few examples of the financial impact:

  • Cost of fixing bugs in production. Fixing bugs in production can be expensive because they cost your organization money, loss of revenue and unhappy customers. It increases your cost per unit and has negative effects on employee productivity because they need to work overtime or work with a buggy system.
  • Cost of lost revenue due to poor quality software. A recent study by Forrester Research states that companies lose $300-400 billion annually due to poor quality software development practices, including lack of testing! According to Gartner Inc., about 50% of all projects are canceled because companies overestimate their budgets for application development projects and don’t factor in costs related to quality assurance activities like testing (i.e., fixing defects before deployment).

The software tester is a liant between the product owner and developers, great communicator, they should be able to identify bugs straight from the documentation

As a software tester, you are a liant between the product owner and developers. Your job is to communicate with both sides to ensure that the product is developed according to plan and that it provides value for its users. You should be able to identify bugs straight from the documentation or specifications document then report this back to your team so they can fix it.


These are just a few of the reasons why it is so important to have a good software tester on your team. We hope that we’ve helped you see why this role is so crucial for any software project and what makes them so valuable.
