youtube.com — Japanese astronaut Takao Doi, on board of the International Space Station, has proved that a boomerang returns to the person throwing it even in the zero-gravity conditions. The idea came to him by request from his friend Yashuhiro Togai, a world boomerang champion. The result is exactly what the science behind boomerangs predicts.

I dug you down because the last paragraph of the article you linked to says: "Now, the question remains as to what will happen if the force of gravity is not present. The zero-gravity environment of the ISS is a perfect place to test this. The atmosphere of the ISS will still allow the boomerang to generate lift, but will it return to the sender, bounce off the walls, or just spin in place?" which kinda contradicts your point of "I have no idea why they actually had to test this..." Did you even RTFA you linked to?

Both are equally silly tests if you know that a boomerang requires air to make it's return. That would make flying it in the space station no different than on earth except without a downward pull towards the ground.
