Imagining the modern world without the Internet is virtually impossible. Every day, people interact with dozens of websites and applications, and as we all know, the better the user’s impression of them, the higher the likelihood that they will become indispensable to those in the digital world.

But while the attractive appearance of the site or program is important, a user-friendly interface is essential

At this point, we can’t say that bug-free software does not exist, but today we want to tell you a little about the heroes fighting bugs hiding in the programming. After all, what is the point of a beautiful website or application if nothing happens when you click on the “buy” button? Or worse, the site gives you the dreaded  404 error.

This is where our Internet exterminators come to the rescue, ensuring the sites and applications are functioning flawlessly, without bugs and crashes, by providing Quality Assurance, or in simple speak – testers.


What kind of animal is this Quality Assurance, and what does it do?

A QA-engineer (Quality Assurance engineer) is a specialist in quality assurance of software development (software) and its functional testing.

It is these people who check the performance of a site, application, game, or specialized software before making it available to the public. There are a huge variety of testers, each requiring different work skills, programming knowledge, and meticulousness in performing their duties.

The more specialists and the higher their skills, the more stable and better the product enters the consumer market. This is where IT corporations such as Google, Facebook, Microsoft, and others succeed. After all, you must admit, it is always a pleasure to open their applications and responsive interface and marvel at the absence of bugs and critical errors, as well as their dedication to providing constant support for their products and, in case of new errors, their prompt correction. It’s a fact that companies are watching their offspring, and every year their products are getting better, and the audience is growing inexorably.

And, it is not for nothing that companies value and rather generously pay testing specialists because they are well aware that it is the engine compartment of applications and programs that plays a key role in selling a product.


As an example, if we go to job search sites from top companies like Google, Facebook, etc., we will see some pretty tempting numbers there. The starting salary for all types of testers starts at $90,000 per year, and over time, it can grow to $160,000 or more, and this is without bonuses that companies almost always and quite frequently payout, especially if you are very good at your job.

At the same time, there is always huge competition for these positions since working conditions and salaries are very good. Such tech giants have various programs to help with relocation and employment. They even help find housing and schools for children. Because of this attitude towards their employees, the world receives excellent testing specialists from various countries – India, Africa, and Eastern Europe.


What would we do without them?

The tester’s task is to test the software before it is released to the general public. It is still impossible to protect yourself from bugs 100% of the time, which is why one of the Itera Research services is a specialist who, even after the development is completed, will control the project and carry out a thorough inspection and program-wide cleanup of bugs.

The modern world is developing and changing very quickly – every day, dozens, if not hundreds of new sites, applications, games, operating systems, and many more products are released that simply need those who will conduct performance tests.


Itera Research has a team of experienced testers, and we are constantly looking for talent. Our QA department performs functional testing at every stage of the software development or after the release. We test mobile applications on real devices. Our test automation engineers turn routine manual tests into automated scripts and prepare all the necessary test data. After all, everything that we all use now, at one time passed through days, if not months, in search of the most minor bugs and flaws – and all this so that the user was satisfied even when the public version of the product was launched.


Thorough, complete, website testing for major websites, spanning dozens of pages can cost hundreds and hundreds of dollars. However, this type of money and the rigorous testing that major corporate websites go through does not preclude the words “do-it-yourself”. Even with only a beginner’s knowledge of testing websites, starting from scratch, will take under a week for a moderately sized website (we’re not talking about testing Wikipedia here). As such there’s absolutely no excuse for checking and testing at least the basics.

Start early

This point can’t be stressed enough. If you wait until the website is complete, or nearly complete then it will be, almost guaranteed, a train wreck. Ideally, you should start testing as soon as you start coding. From day one, test and test again so that you can discover where things are going wrong, as they are going wrong. This helps avoid playing the part of detective as well as avoiding catastrophic errors before they become a catastrophe.

Baseline requirements and acceptable protocols

As with nearly everything to do with design – some parts are more subjective than others. It is important to know who your audience is and what they use primarily (to make sure it definitely works on their terms) and set acceptable limits on what you accept as a success or failure. Your idea of failure might be not working with the most current version of Mozilla, whereas one tester’s idea might be the website not working on Netscape 4.

Different strokes for different folks

That being said, there is a whole plethora of websites and operating systems in the big wide world. Make sure that, at the very least, it works on the big four: Internet Explorer, Safari, Chrome, and Mozilla. However there are plenty of free programs that emulate browsers on mobile phones and tablets and it definitely pays to have responsive designs in our smartphone-enabled world.

CSS stress test

This is a big one – make sure, make sure and make sure again that you have validated all of your CSS. Not only each external sheet, but any embedded and in-line code as well. This is the ‘biggy’ that can really throw off a new website.


Make sure you optimize each webpage at every stage of development. Make sure every piece of code needs to be there and, if you followed the advice from point one, don’t be afraid of stripping out code that doesn’t seem to belong. It’s much easier to do during the development stages than a ‘house-of-cards’ situation when some seemingly redundant script turns out to be load-bearing and you can’t figure out why. There are plenty of html editors that can highlight suspected redundancies for you and these are fully recommended.

404 errors

These are one of the biggest pitfalls of any developer and errors here, being quite common, will expose the amateur. These are easily tested by intentionally entering the wrong address into the browser. These are important because they help the user of the webpage know what’s wrong and what to do/where to go next.

While you’re at it – check all the links and downloads manually to make sure they point to the right places. There is software out there that can help with this.


This point can’t be stressed enough. While nothing to do with the code, this is what the user will see and if you don’t recognize the “your” from your “you’re” then they’ll notice.

Usability tests

Get a colleague or even partners and friends to use your website. Set them tasks (e.g., ask them to find a contact email) and ask them how easy it was to complete. There’s nothing like a fresh pair of eyes to highlight things you are too close to the project to see.

So these are the top things to look out for when writing a website. Obviously, there are hundreds more but these are the most common and by sorting these out you will have fixed 90% of the problems any new website can experience.
