It is called a streak and its purpose is to find the hardness of the mineral.
You can tell if a mineral can scratch another mineral by performing a scratch test, where you use the hardness scale to compare the minerals. If the mineral you are testing can scratch the other mineral, then it has a higher hardness on the scale.
Geologists focus on the hardness property of minerals when they perform scratch tests. This test helps determine the resistance of a mineral to being scratched by another material, which can be indicative of its mineral type.
The scratch test measures a mineral's hardness, which is its resistance to being scratched. This property is identified by comparing the hardness of a mineral to the hardness of known minerals on the Mohs scale.
A scratch test in geology is used to determine the hardness of a mineral. By scratching one mineral with another, geologists can assess which mineral is harder based on the scratch produced. This allows for the identification of minerals based on their relative hardness levels.
The hardness of a mineral is tested using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest). A common method is to scratch the mineral with a known material of a specific hardness to determine where it falls on the scale.

The scratch test, use a series of mineral with known hardness and scratch the mineral. From softest to hardest, and note where a scratch is made. You can also look for distinctive physical characteristics.
You could perform a scratch test by trying to scratch one mineral with another. Whichever mineral leaves a mark or scratch on the other is harder. By comparing the results of scratching each mineral with the others, you can determine their relative hardness.
You can tell if a mineral can scratch another mineral by performing a scratch test, where you use the hardness scale to compare the minerals. If the mineral you are testing can scratch the other mineral, then it has a higher hardness on the scale.
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

By undergoing scratch test.
Geologists use the Mohs scale of mineral hardness to characterize the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. In this scale diamond is the hardest material and talc the softest.
Mineral hardness is tested on a glass plate or usually a finger nail.
Most likely you would be testing to see if the mineral was harder or softer than the nail.
