practice run

Feel free to use this sort-of-sad break up as a practice run for the sure-to-be-devastating demise of Bey and Jay.

Still, as she noted in the Nouvel Obs interview, that acted as a de facto practice run for this book.

The men are lowering, for stowage in safety, a trial torpedo which has been fired for a practice run and then re-captured.

As they tied up after the last practice run Zircon called them to eat, then instructed them to get some sleep.
