The streak test is not a very good identifier of rocks because rocks are composed of combinations of minerals which may have different color streaks. The streak test is mainly used in mineral identification. Even then, it is used in common with other indicators, like hardness, crystal system, and chemical composition.

a streak test is a test wheree you rub a mineral across a streak plate to see the color of its streak, which is a better indentifying factor of the mineral than the external color. A scratch test is when you scratch a mineral to find out its hardness on the Mohs Scale of Hardness. This is also another useful identifying factor
