testée

Testée is the feminine singular past participle of the French verb tester, meaning that something has undergone testing. It can function as an adjective meaning “tested” and is used to form compound tenses with auxiliary verbs. The related forms are: testé (masculine singular), testée (feminine singular), testés (masculine plural), et testées (feminine plural).

In practice, testée appears most often in written and spoken French to describe a feminine singular noun that has been subjected to testing. When the past participle is used with the auxiliary avoir, its ending agrees with a preceding direct object. For example, “Les procédures testées ont été approuvées” shows agreement with “procédures.” If the direct object comes after the participle, no agreement occurs, as in “Nous avons testé les procédures” where the participle remains in its masculine singular form.

Pronunciation is typically [tɛ.ste], the same as the masculine form tester in many contexts. The word is widely used across domains such as science, software development, engineering, and consumer testing, and it also functions as a generic adjective in phrases like “une méthode testée et validée.”

Etymology is straightforward: testée derives from tester, a French verb that means to perform a test. It is part of a broader set of participial forms that align with gender and number to describe the outcome of testing.
