product test

hi guys, are you ok? I have a doubt, one of the things that I have difficulty with is testing products, I'm still going to start in dropshipping, I've seen several professionals who work in this field, only they spend doing testing with a lot of money, and recently I heard about a strategy that you spend a lot little, the name is minimum viable product (MPV), so I'm not able to find much about it in my research or is there another method to test products with very little budget and see if this product has scale?

thank you for help

I'm brazilian
