About 1/3 of the way into the movie. Obi-Wan suggests to Yoda to promote Anakin to Jedi Knight, because they need more knights due to the war. Obi-Wan also said, Anakin has faced more challenges than the Jedi trials. Obi-Wan wouldnt know what the trials were, because he was promoted to Jedi Knight by defeating Darth Maul, not facing the trials.
