Testoj

Testoj is the plural form of the Esperanto noun testo, which means a test, examination, trial, or experiment. The term is used broadly across contexts to refer to an organized assessment or verification procedure.

In education, testoj refer to examinations or assessments that measure a learner's knowledge or skill. In science and engineering, they denote experiments and validation procedures that verify hypotheses or the performance of a system. In software development and quality assurance, testoj describe test cases and test runs used to verify a program’s behavior. The word is widely understood among Esperanto speakers and is regularly used in technical and educational texts.

Grammar-wise, testo is formed from the root test- with the nominal suffix -o. The plural is testoj following the standard Esperanto plural suffix -oj. Esperanto has no grammatical case, and possessive or relational meanings are indicated with prepositions such as de.

Nuances: testo tends to imply formal assessment or objective verification, whereas provo more often denotes an informal attempt or trial. Ekzameno is commonly used for formal exams.

Examples: La lernanto faris plurajn testojn. La programo pasis ĉiujn testojn. These sentences illustrate typical usage in educational and software contexts.
