Testatuilla

Testatuilla is an informal term used in some Spanish-speaking contexts to denote a small, quick test or trial. It derives from the English word test and the Spanish diminutive suffix -illa, signaling a minor check rather than a full examination. The word is not part of standard dictionaries and its meaning can vary by user or setting.

In practice, testatuilla appears in software development, educational settings, and quality assurance as a colloquial label for brief validations, sanity checks, or quick demonstrations that show whether a concept or component functionally behaves as intended. It is typically understood only within a given team or community, and may differ in scope or rigor from one context to another.

Because of its informal nature, testatuilla can create ambiguity in formal documents. For this reason, writers often substitute more established terms such as prueba, test, ensayo, or revisión. Some speakers also spell variants like testatilla or testatuella, reflecting regional pronunciation and orthography.
