Dress rehearsal

We've got three dress rehearsals before the opening night to prepare ourselves for any potential technical issues.

Although the train derailment ended up not being very serious, the emergency services' response served as a dress rehearsal in case of a much worse disaster.

Sunday, November 6, was spent in a second full-scale dress rehearsal of the complete weekday electric timetable, [...] during which the public were invited to make their first trial of the trains—and 15,000 did so.

And if anybody thinks that that was not a dress rehearsal for what they may try to attempt in January of 2025, I’m sorry to say, but I think that’s a very naïve assumption.
