Test for wave properties: refraction, diffraction, interference patterns. Also realize that due to quantum wave-particle duality, it's technically bound to be both.

In fact our present model is that all matter and radiation can be considered as particles or waves.
Massive objects (big enough to be visible to the naked eye) have such short wavelengths that the wave behaviour becomes undetectable; while tiny "particles" such as electrons and photons have clear wav properties, and their particle behaviour becomes less clear.
In 1924, Louis-Victor de Broglie formulated the de Broglie hypothesis, claiming that all matter, not just light, has a wave-like nature; he related wavelength (denoted as λ), and momentum (denoted as p):
λ = h/p where h = Plancks constant
"Whether objects heavier than the Planck mass (about the weight of a large bacterium) have a de Broglie wavelength is theoretically unclear and experimentally unreachable; above the Planck mass a particle's Compton wavelength would be smaller than the Planck length and its own Schwarzschild radius, a scale at which current theories of physics may break down or need to be replaced by more general ones."
