Yes, provided that you put main in backup mode and then do a PITR when you bring up this new test instance. If your main DB is running but absolutely idle, you might get away just starting it in which case the postmaster will do a regular crash recovery but I'll presume your source instance 'main' isn't idle. Study the manual sections relating to backup/PITR.
