 +====== Observation ======

 +
 +===== Discussion =====
 +
 +An Observation records information detected, measured, received, or otherwise obtained while examining an object, activity, event, or condition.
 +
 +During a [[public:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]], an Observation records an aspect of the behavior, state, output, performance, or operating conditions of a [[public:99_annexes:annex-b-terms-and-definitions:c:candidate_solution|Candidate Solution]] or its [[public:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]].
 +
 +An Observation records what occurred without determining whether the observed information satisfies an expected result or acceptance criterion. Evaluation of one or more Observations produces a [[public:99_annexes:annex-b-terms-and-definitions:t:test_outcome|Test Outcome]].
 +
 +An Observation may contribute to [[public:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] after DIDO-TE preserves the information, its source, its context, and its provenance.
 +
 +===== Definition =====
 +
 +//information obtained by detecting, measuring, receiving, or otherwise examining a property, state, behavior, event, or condition//
 +
 +===== Source =====
 +
 +Adapted from the observation concepts described by:
 +
 +  * [[https://www.iso.org/standard/82463.html|ISO 19156:2023, Geographic information — Observations, measurements and samples]]
 +  * [[https://csrc.nist.gov/glossary/term/Test|NIST Computer Security Resource Center, “test”]]
 +
 +===== Note =====
 +
 +An Observation remains distinct from its interpretation.
 +
 +For example:
 +
 +  * “The service returned status code 503” records an Observation.
 +  * “The service failed the availability criterion” records a Test Outcome.
 +
 +An Observation record identifies the applicable:
 +
 +  * Test Execution
 +  * Source
 +  * Observed property, state, behavior, event, or condition
 +  * Observed value or description
 +  * Time of observation
 +  * Collection or measurement method
 +  * Measurement unit, when applicable
 +  * Relevant operating conditions
 +
 +===== Example =====
 +
 +During a Test Execution, DIDO-TE records that the Candidate Solution rejected a Transfer Bundle and returned status code 403 at 14:32:18 UTC. This record constitutes an Observation. Comparison of the Observation with the expected behavior determines the Test Outcome.
