How can one prove with tests they are female while their genetics gave them the opposite sex as a gender?

Can't be done. It's all subjective. We've discussed the so-called "gender tests" here in other threads... they are all built on asking vague and subjective questions of the taker. That is to say, there is nothing definitive in the way we might test blood for diabetes, or identify a viral pathogen.

However, to be fair, that is not the case with intersex conditions, which are chromosomal in nature. These are physical differences, and repeatably testable. It is also true that many 'transgender' people may simply be intersex and not be aware of it.

That isn't to dismiss the feelings people may have... it's just important to remember that feelings are not an accurate measure of anything but one's feelings.

Just because you don't believe in the validity of gender tests does not mean they are invalid. They have there place and use.
