testés

Testés is the masculine plural past participle of the French verb tester. It appears in two main grammatical situations: as part of a passive construction with the auxiliary être (for example, les échantillons ont été testés) and as an adjectival modifier agreeing with a noun (for example, des produits testés, des échantillons testés). In both uses, the form indicates that testing has taken place.

Morphology and agreement. Testé, tested, testée, and testées are the other standard forms, corresponding to masculine singular, feminine singular, and feminine plural. In passive constructions with être, the participle agrees in gender and number with the subject of the sentence. When used as an adjective, testés agrees with the noun it modifies (e.g., produits testés).

Usage and context. Testés is common in science, industry, medicine, and software testing, where objects, samples, or people undergo evaluation. Examples include: « les échantillons ont été testés pour la résistance »; « des produits testés montrent une stabilité accrue »; « les sujets testés ont fourni des résultats positifs ». The term also appears in phrases like « non testés » to denote the opposite, untasted or unexamined items.

Semantics and relation to related terms. The word derives from the verb tester and is often used in conjunction with terms such as test, testage or évaluation in broader discourse about verification, validation, or quality assurance. As a past participle, its precise meaning depends on the tense and the syntactic role (passive voice or adjective) it occupies within a sentence.
