A scheduled test of the equipment, with the alarms going off randomly all day as the tester gets to them, doesn’t require you to evacuate.
Such a test is always supposed to be preceded by ample warning notifications, so people will be extra careful not to set real fires while the building is vulnerable.
And also is supposed to be monitored with people actually watching for fires so they can manually evacuate people if a fire does break out during the test. (Requirements may vary by jurisdiction of course)
