Is there a way to test a new board?

I apologize if this is the wrong forum section for this question.

I bought what I thought was an official UNO board, but there are some differences. The default blink program runs when I apply power, and the chip looks authentic but I was wondering if there was a home tinkerer way of testing all outputs/inputs.

Thank you for your time!

Thanks again!
