testado

Testado is the past participle of the Portuguese verb testar, meaning that something has undergone testing, examination, or verification. It functions as an adjective and as part of verb tenses formed with auxiliary verbs. As an adjective, it agrees in gender and number with the noun: testado (masculine singular), testada (feminine singular), testados (masculine plural), testadas (feminine plural). It is also used in compound tenses: ele tem testado várias soluções; o produto foi testado.

In usage, testado commonly appears in contexts related to quality control, safety labeling, software development, and scientific research to indicate that a product, method, or hypothesis has been evaluated. Examples include "produto testado e aprovado," "versão testada do software," and "paciente testado em estudo clínico." The noun corresponding to the process is "teste," while the adjective form "testável" describes something that is capable of being tested.

Related terms and notes: antonyms include "não testado" or more rarely "intestado." See also testar, teste, testabilidade. The term is widely understood across Portuguese-speaking regions and is used in both everyday language and technical or regulatory contexts to convey that an item or claim has undergone formal evaluation.
