Who is tester

The tester creates conditions for the software to work, noting its strengths and weaknesses. They develop tests that check the functionality, reliability, and security of the program. The tester runs these tests, analyzes the results, and determines whether the program meets the requirements. They identify errors and inconsistencies, document them, and communicate with the development team for correction. The tester also explores user experience, checking how easy it is to work with the program. They may propose improvements based on user needs. Regularly working on projects, the tester adapts to new technologies and tools, helping to enhance testing processes. With their attention to detail, they ensure the high quality of products that enter the market.

AI impact on tester

Medium risk

AI replacement risk

50%

Writing basic test scripts and running the same functional checks over and over will increasingly be done by AI and existing automation, so you'll spend less time on repetitive clicking and more time deciding what's worth testing. The tasks that stay are digging into weird crashes, reading requirements to spot gaps the machine would miss, and talking with developers to figure out why something broke in production. Your day-to-day shifts toward designing tricky scenarios, poking at edge cases, and judging whether a bug is real or a misunderstanding.

Tasks at risk of automation

Writing basic test scripts
Running repetitive functional checks
Preparing routine testing reports

Tasks that will remain human

Designing tricky test scenarios
Investigating weird crashes and edge cases
Collaborating with developers to resolve issues
Analyzing requirements for gaps

How to become a tester

You can become a software tester in the UK without a degree — many companies value practical skills and a portfolio over an academic qualification. The fastest route is an online QA/testing course or a bootcamp, followed by a junior role. The ISTQB Foundation Level certificate is a widely recognised credential that strengthens your CV.

1. Online courses and bootcamps

Online QA courses and bootcamps teach the basics of manual testing, test design and tools such as Selenium, Postman and JIRA. They typically run two to four months, after which you can apply for Junior QA roles. The ISTQB Foundation Level certificate is a useful add-on.

2. Apprenticeship or junior placement

Many UK tech companies offer software testing apprenticeships or junior placements. You learn on the job, working on real tasks under an experienced tester, and earn while you train.

3. Self-study and portfolio

You can learn the fundamentals yourself using online resources and practice projects, building a portfolio that demonstrates your skills. This is a strong route into a first role, especially combined with the ISTQB Foundation certificate.

The fastest route is an online QA course or bootcamp followed by an apprenticeship or junior role at a tech company. An ISTQB Foundation Level certificate noticeably strengthens your CV. From there, your level grows with experience on real projects.
