Accretion disks around black holes\, both the supermassive variety in the centers of galaxies and those in the stellar mass range present in X-Ray binaries\, allow us to probe the spacetime near the black hole event horizon using electromagnetic observations. Currently\, the two effective methods of studying such observations are known as X-Ray reflection spect roscopy and the continuum-fitting method. Together these methods have been used to estimate the properties of several dozen black holes (though not always in agreement with each other). In this talk I will go over the basi cs of X-Ray reflection spectroscopy and the continuum-fitting method\, pre sent how they can and have been used to test gravity\, and discuss some of the open issues and how we are trying to study and address them. span>
