Lecture
A Software Tester (QA Engineer) is a specialist who checks programs and applications for compliance with requirements, identifies defects, and evaluates usability. Their work ensures the quality, security, and stability of digital products.
Studying technical documentation, specifications, and user scenarios.
Clarifying requirements with business analysts and developers.
Writing test cases and checklists.
Preparing test data.
Defining acceptance criteria.
Manual testing of interfaces, logic, and security.
Test automation using frameworks (Selenium, Cypress, JUnit).
Regression, functional, load, and integration testing.
Describing defects in bug-tracking systems (Jira, Bugzilla).
Prioritizing and tracking the status of fixes.
Working together with developers, DevOps engineers, and analysts.
Participating in daily standups and retrospectives.
Providing reports on testing progress.
Root cause analysis of defects.
Proposing improvements to product quality.
Supporting CI/CD processes and automated builds.
Vision: good or corrected with glasses/lenses, since the job involves prolonged analysis of interfaces and code.
Musculoskeletal system: no serious problems with the spine or joints, since the job involves many hours of sitting.
General health: tolerance for a sedentary lifestyle, prevention of dry eye syndrome and carpal tunnel syndrome.
Tolerance for monotony: testing is often repetitive.
Attentiveness and concentration: the ability to notice small inconsistencies.
Stress resistance: the ability to work under deadlines and criticism.
Communication skills: interacting with developers and managers to describe defects.
Basic education: most often technical (computer science, programming).
Courses and certifications: ISTQB, QA Automation, Selenium, Jira, SQL.
Skills: knowledge of programming languages (Python, Java), test management systems, and databases.

The software testing profession (Software Tester, QA Engineer) emerged almost at the same time as the first computer programs.
1950–1960s
In the era of the first computers, programmers checked their own code themselves. Testing was seen as a side task — it was simply necessary to make sure the program «worked». Errors were costly: a single failure could bring an entire computing center to a halt.
1970s
An important turning point occurs. American scientist Glenford Myers formulates the idea that:
«The goal of testing is not to prove that a program works, but to find errors».
It was then that testing became a separate discipline rather than a part of programming.
1980–1990s
With the growth of personal computers and mass-market software (operating systems, office suites, games), the volume of software increased sharply. There arose a need for:
system testing,
regression testing,
defect documentation.
The software tester emerges as a separate role on the team.
2000s
The internet, web applications, and mobile devices make testing even more complex:
different browsers,
different devices,
high load,
data security.
Specializations emerge:
Manual QA
Automation QA
Performance / Load testing
Security testing
2010–2020s
Agile, Scrum, and DevOps methodologies blur the boundaries between development and testing. The tester becomes a participant in the entire product lifecycle, rather than «the person at the end of the chain».
A software tester is a specialist who:
verifies that the product meets requirements,
looks for errors and weak points,
evaluates usability,
prevents financial and reputational losses.
The tester’s main focus is quality and user experience, not just «finding bugs».
Although testers are rarely public figures, there are people who have had a huge influence on the profession.
Author of “The Art of Software Testing” (1979).
Laid the foundations of modern testing.
Introduced the concepts of negative testing and test design.
One of the leaders of exploratory testing.
Promotes the idea of testing as an intellectual activity, not a set of scripts.
A critic of blind automation without understanding the product.
Co-author of the modern approach to exploratory testing.
Focuses attention on the tester’s thinking, rather than on tools.
A popularizer of Agile testing.
Co-author of the book “Agile Testing”.
Contributed to integrating QA into Scrum teams.
Today a tester is:
an analyst,
a researcher,
a user advocate,
a developer’s partner.
Skills of a modern QA engineer:
understanding of software architecture,
basic programming,
analytical thinking,
knowledge of business logic,
communication.
The short answer: no, but it will change significantly.
automatically generates test cases;
writes autotests;
analyzes logs and finds anomalies;
predicts areas with a high risk of errors.
routine manual testing against checklists;
mechanical verification of repetitive scenarios;
simple regression testing without analysis.
exploratory testing;
evaluating the usability and logic of the product’s behavior;
checking complex business scenarios;
identifying non-obvious errors;
ethical and context-based decisions;
interacting with the team and the client.
AI does not understand the value of a product the way a human does, and it does not feel the context of the real user.
The tester of the future is:
QA Engineer + Analyst + AI partner
a specialist who:
manages AI tools,
formulates the right questions,
interprets results,
is responsible for the final quality.
The focus will shift:
from «checking» → to preventing errors;
from test cases → to thinking and risk analysis.
QA Automation Engineer (test automation).
DevOps Engineer (process integration and support).
Business Analyst (requirements analysis).
Software Developer (software development).
UX/UI Designer (interface usability).
Conclusion: A software tester is a profession at the intersection of technical and psychological skills. It requires attentiveness, resilience, and continuous learning. Salaries vary by country, but the profession is in demand everywhere and has growth prospects.
The testing profession:
arose from the need to trust programs,
has evolved from a supporting role to a key member of the team,
will not disappear with the development of AI, but will become more intellectual and strategic.
The future of QA is not about finding bugs, but about managing quality in complex digital systems.
