Testihenkilöitä
A testihenkilö, often translated as a test person or tester, is an individual who participates in a trial or experiment to evaluate a product, service, or process. This can range from software testing, where individuals use a new application to identify bugs and usability issues, to product testing, where participants use consumer goods and provide feedback on their performance and features. In a broader sense, testihenkilöitä can also refer to people involved in medical trials, academic research, or even field tests of new technologies.
The primary role of a testihenkilö is to provide honest and constructive feedback based on their experience.
