Lisätestein

Lisätestein is a Finnish term describing the practice of performing additional tests beyond the standard testing procedures. It is used in several fields to verify results, assess reliability, or meet regulatory or contractual requirements.

In software development, lisätestein refers to supplementary tests added after an initial testing pass to uncover edge cases, integration issues, performance under load, or compatibility with external systems. These tests are often planned within iterative development cycles and can include exploratory testing, automated regression checks, and targeted manual verification.

Outside software, lisätestein appears in contexts such as manufacturing quality assurance and clinical research, where extra studies or test runs are conducted to reduce uncertainty, validate measurements, or satisfy safety standards. The exact scope and methods vary by industry, governing bodies, and risk assessment, but the underlying principle is to increase confidence in outcomes by collecting additional data.

Implementation typically follows a risk-based approach: defining objectives, selecting test scenarios, allocating resources, and ensuring traceability from test cases to requirements. The term is primarily used in Finnish-language documents and is not widely standardized as a formal methodological term across industries.
