The statement that accurately describes streak is: **Streak is tested by scraping a mineral across a streak plate.**

Streak is defined as the color of the powder produced when a mineral is scraped across a streak plate, which is typically unglazed porcelain. The color of the streak does not necessarily match the color of the mineral itself, making it a useful diagnostic tool in mineral identification.
