Materials for a live round are only published when that round ends, of course.
Some (difficult / error-prone, etc.) problems will have a test generator that can generate large amount of input (and sometimes output) for debugging. There may also be files like problem.in which contains test cases that had caused me problems and took me a long time to realize what's wrong.
Some *.in files will have corresponding *.out files, representing the expected output. Otherwise, you can simply download the top solvers' code and run it on your input.
