What theory is that? How would it be tested? Gravity is not even a force, it is a consequence of how space deforms around mass&energy. So, even if something like "negative mass" existed, it wouldn't repel, it would just cancel out.

The cancle out your talking about is what happens with magnets and dipoles. What if negative mass was a monopole?

Testing the theory would be be the same kind of tests created for testing the Big Bang.
