Who is tester

The tester immerses himself daily in the process of testing various products, checking their reliability, safety, and quality. He develops and implements tests, analyzes results, and makes adjustments. The tester constantly interacts with the development team to discuss identified flaws and find ways to address them. In his work, he uses a variety of tools and methods to verify the characteristics of materials or devices. The tester also documents all stages of testing, compiles reports, and suggests improvements based on the data obtained. By paying detailed attention to every aspect, the tester ensures that the product meets the highest quality standards before entering the market.

AI impact on tester

Medium risk

AI replacement risk

50%

Writing basic test cases and running the same regression checks after every small change will increasingly be done by AI, so you'll spend less time on repetitive scripts and more time poking at weird edge cases the model missed. What stays is figuring out why a feature feels broken in ways the logs don't show, talking with developers to untangle a nasty bug, and deciding when something is safe to ship. Your day-to-day shifts toward exploratory testing, arguing about requirements that don't make sense, and checking that fixes actually solve the problem instead of just making the test light turn green.

Tasks at risk of automation

writing routine test cases
running repetitive regression tests
drafting standard test reports

Tasks that will remain human

exploratory testing and finding subtle bugs
working with developers to resolve tricky defects
deciding if a fix is good enough to ship

Work schedule and conditions

A tester typically works 8 hours a day. The schedule can be from 9:00 AM to 5:00 PM or flexible. The weekends are usually Saturday and Sunday. The job is mostly in an office, but there is the possibility to work remotely. Additional working conditions may include overtime or participation in projects from various countries.

How to become a tester

You can become a software tester (QA) quickly and without a degree in the UK. What matters most is understanding how software works, attention to detail, and the ability to describe defects clearly. Manual testing basics can realistically be learned in a few months through a course or bootcamp.

1. Short courses and bootcamps

Short courses or bootcamps in manual testing are the quickest start. In a few weeks to a few months you learn the basics — types of testing, working from requirements, writing bug reports and using issue trackers — enough to apply for your first junior role.

2. Internship or junior QA role

An internship or junior position at a tech company lets you learn on real projects under experienced engineers. Many product and outsourcing firms take people on with no experience and train them on site — a fast way into the profession.

3. A university degree

A degree in a technical or computing subject gives a deeper understanding of development and computer science, useful for moving into test automation. It is not required, though — most testers enter the field through courses and practice.

The fastest route is a short testing course or bootcamp plus an internship or junior QA role. From there, add automation (Python, SQL, testing tools) and an industry certificate such as ISTQB Foundation — these raise your value in the job market.
