I guess I would put it this way in regards to comparing Rey and Luke in their respective middle entries of their trilogies.

With Luke, we saw his psychological struggle with things like his trial in the cave and when he figures out that Vader is his father. But you also get his physical struggles with the actual force like Dre said. Luke fails consistently throughout the movie in regards to force related feats.

With Rey in the Last Jedi, I think there is a very good psychological struggle that we see with her. She grapples with finding her place in the galaxy, seeing legends as real fallible humans, and defining her own path. She experiences a lot of emotional pain when she has to part ways with Kylo.

But she obviously lacks any of the physical/force challenges that Luke had. She does breeze through everything force related.

So when people say that Rey in TLJ underwent no trials, then I would object. But I do admit that she didn’t get quite the sphere of challenges as Luke did in the Empire Strikes Back.
