Astrophysical black hole candidates are thought to be the Kerr black holes of general relativity, but there is not yet direct observational evidence that the spacetime geometry around these objects is described by the Kerr solution. The study of the properties of the electromagnetic radiation emitted by gas or stars orbiting these objects can potentially test the Kerr black hole hypothesis. This paper reviews the state of the art of this research field, describing the possible approaches to test the Kerr metric with current and future observational facilities and discussing current constraints.

Testing the rotational nature of the supermassive object M87* from the circularity and size of its first image (2019, background): “As argued in [29], this detection already qualitatively rules out several exotic alternatives to that of M87* being a “standard” Kerr BH [46, 47].”
Testing the Kerr Black Hole Hypothesis Using X-Ray Reflection Spectroscopy (2016, background): “The Kerr black hole hypothesis can be tested by studying the properties of the electromagnetic radiation emitted by material orbiting a black hole (Johannsen 2016; Bambi 2017; Krawczynski 2018; Zhou et al. 2019b).”
