How do you test out a streak?
by strecting it on a streak plate
Would the hardness of a mineral affects its performance in the streak test why or why not?
No. Streak color is distinct of mineral hardness. They are separate properties.
How do you know a mineral's streak?
The streak of a mineral can distinguish between two samples that have the same color. The streak is often a different color. To test streak, use a streak plate. This is a piece of unglazed porcelain, like the back side of a tile.

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
