Testitilanne

Testitilanne is a Finnish testing term describing a clearly defined set of conditions under which a test is performed. It is often translated as testing situation or test scenario. A testitilanne specifies context, inputs, environment, and expected outcomes to ensure reliable interpretation of results. The concept is used in software testing, quality assurance, education, and usability research.

Its purpose is to provide a controlled, repeatable framework to determine if requirements are met, to assess performance and safety, and to identify defects. A well-defined testitilanne isolates the tested item from external variability and supports traceability to requirements and acceptance criteria.

Core elements include: objective, environment (hardware, software, network), inputs or user actions, preconditions, execution steps, expected results, measurement methods, and documentation such as identifiers and version information.

Examples: In software development, a login testitilanne may specify browser, valid and invalid credentials, and expected outcomes (successful navigation or an error message). In education, an exam scenario may define time limits, permitted materials, and prompts to standardize conditions across participants.

Creation and governance: test plans and requirements drive testitilanne design; they are reviewed by stakeholders and linked to defect reports. In regulated contexts, they support validation, verification, and quality management.
