Testerzy

Testerzy is a Polish term referring to professionals who perform testing to assess the quality of products, especially software. The word is a direct borrowing from the English “tester” and is used in Polish-language contexts to designate individuals in the quality assurance and testing domain. It describes people working in software development, hardware verification, or product QA processes.

Typical responsibilities include planning and designing test cases, executing tests (manual or automated), documenting defects, retesting fixes, and maintaining test documentation and quality metrics. Testerzy collaborate with developers, product managers, and UX teams to identify risks, verify requirements, and ensure that software meets functional and nonfunctional criteria such as reliability, performance, and usability. They may specialize in areas like functional testing, regression testing, exploratory testing, or automation engineering.

Skills commonly associated with testerzy include critical thinking, attention to detail, and clear communication. They work with various tools and environments, such as bug-tracking systems (e.g., Jira), test management tools (e.g., TestRail), and automation frameworks (e.g., Selenium, Playwright, Cypress). The role may be filled by QA engineers, test analysts, or software testers and can involve on-site or remote work depending on the organization. In Poland, testerzy are a common professional category in IT companies, startups, and outsourced QA service providers.
