Put down your Jaco Pastorius, Victor Wooten, Les Claypool and the like. You have no need for that. Further, the most offensive part of your post wasn't in saying that this or that instrument is easy or is not, it's in your request for "difficult" material to test yourself.
If you want to test yourself, if you want the most virtuosistic performances ever, you will not learn what bass is about.
Bass is about feel, time and groove. You are, for all intense purposes, a rhythm player. Your job is not flash, it is solid time. The biggest problem I find in guitarists that convert to bass is not in technique or chops, although they are usually poor too. The biggest mistakes I find are in time and feel.
You want something difficult? Get out a metronome, and get out your bass. Bring a tape recorder. Set the metronome to 50bpm, and play an open E string on the click. Focus on making the click of the metronome disappear. Listen back to the recording. How was your feel? Your attack? Your tone? Your time??? Listen to the drums for a change.
While bass and guitar are both "guitars", that is the end of the similarities, THE ROLE AND FUNCTION OF THE TWO INSTRUMENTS ARE INTRINSICALLY DIFFERENT!
Listen to "My Girl", by The Temptations. That, my friend, is difficult. That, my friend, is bass.
Screw Claypool, Jaco, and Vic. They are something totally different than what the vast majority of bass players are. You want the gig, you want to be the one getting the call, focus on your rhythm and feel.
