There are several synonyms for test screening, including preview screening, audience testing, and sneak preview. Preview screening is a generic term that refers to an advance showing of a film or TV show before its official release. Audience testing is a more specific term that describes the process of gathering responses from a carefully chosen group of people. Sneak preview typically refers to an early showing of a film meant to generate excitement and buzz before its release. Regardless of the term used, test screening remains an important tool for filmmakers looking to get feedback and make necessary adjustments before their work is shown to the public.
