Today, in IT, you can hear the abbreviation more and more often QAMany beginners are confused: who are QA engineers, what do they do and how is their work related to developers. Let's break it down in simple terms.
QA (Quality Assurance) is the process of ensuring product quality. The main goal is to ensure that the user receives an application or service that works stably, safely and meets the requirements.
QA is not just about finding bugs. It is a whole philosophy, including:
writing test cases and scripts;
test automation;
performance and safety checks;
risk analysis and improvement of development processes.
Who is a tester?
A tester (or QA engineer) is a specialist who checks how well the product works. Their main task is to find errors before the user encounters them.
Tester:
thinks like an end user;
checks the application on different devices and in different scenarios;
fixes bugs and helps developers fix them.
How is a tester different from a developer?
Criterion | Developer 🧑💻 | Tester 🔍 |
|---|---|---|
Main objective | Write a working code | Check code quality |
Approach | "How to implement?" | "What can break?" |
Tools | Programming languages, frameworks | Bug tracking systems, test cases, automation |
Result | Ready-made functionality | Stability guarantee |
Thinking | Creative | Critical |
Why do we need both roles?
If you remove the developers, there will be no product. But if you remove the testers, the product will come out with errors and a poor user experience.
Therefore, developers and QA engineers are a union where everyone is responsible for their part, but together they create reliable IT solutions.
How to enter the QA profession?
Testing is a great entry point into IT for beginners. It helps to develop analytical thinking, learn how to work with teams and gradually move into automation or even development.
