In the context of video game assembly, what does the test instruction do?

I notice that in a lot of games, instructions like 'test rax,rax' would appear. What does it do? Is it like the compare instruction where it sets specific flags? I checked the wiki but it still doesn't make sense. I'm hoping someone can simplify this for me.
