1. A method for controlling a pump test run for a pump of a water extinguishing system, wherein the method comprises the following steps:
providing a fluid bypass line having a reduced cross-section compared with a test line branching off from a supply line of a pipe system, wherein the fluid bypass line is configured to conduct a predefined portion of an extinguishing fluid around an opening element of the test line away from the pipe system,
determining at least one parameter indicative of the cross-section of the fluid bypass line, and
controlling, based on the at least one parameter, the pump test run of the pump.
