Catapult testing would have little or no part in the commissioning, I would think. Both Liaoning and Shandong were commissioned for months before air trials began.
Commissioning happens after sea-keeping and sea-worthiness tests. Bulk of testing for the launch and recovery systems and air wing should come after the Navy takes over.
The problem is the post made by Henrik (below) suggested they had done extensive testing in the shipyard and is implying it has already solved many issues that would precede commissioning, and Deino's posts have been to disabuse him of that notion.
At 4.20PM movement of the group has stopped. May be they are trying to turn the bow of CV18 around to the river mouth.

Everyone should be telling Henrik that his post makes no sense and that there is still extensive sea trials and aviation testing to be done prior to commissioning, and what tests they had done at dockside in port is far from sufficient to even broach the idea of commissioning in the near future.
Deino is just being too polite and insufficiently direct by asking "what have they intensively tested" rather than just outright pushing back and saying what tests they've done in port/dockside is far from sufficient to near commissioning, which in turn opens it up for people to answer his question while not understanding the context of what he wrote is meant to deny the suggestion made by Henrik.
