teostest

Teostest is a term found in Estonian technical literature describing a class of tests focused on the execution, deployment, or performance of a system, product, or process under realistic conditions. Its exact scope varies by field, but it commonly covers end-to-end validation that the system performs as intended when operated in a real or simulated environment.

Etymology and usage: The word is derived from Estonian teostus, meaning execution or implementation. In practice, teostest can refer to tests that verify operational readiness, reliability, and compliance with specified workflows, rather than isolated unit checks.

Applications: In software development teostest may involve validating a full workflow from input data through processing to output, often in staging or production-like environments. In manufacturing or engineering, teostest can mean testing the assembled system under service-like conditions, including integration with subsystems, monitoring, and fault handling.

Methodology: A teostest program usually begins with defining objectives and success criteria, preparing a realistic test environment, and creating end-to-end test cases. Execution is followed by result gathering, defect logging, and evaluation against acceptance criteria. Risk-based prioritization is common.

Relationship to other testing: Teostest is distinct from unit, integration, or performance testing, as its emphasis is on actual operation and deployment readiness. It often acts as a bridge between development and production.

Notes: Because there is no universal standard definition in English-language sources, interpretations of teostest can vary between organizations and industries.
