	The European X-ray Free Electron Laser (XFEL) is currently under construction in Germany in Hamburg area. A linear accelerating part of the XFEL is going to consist of 808 superconducting 9-cell Niobium cavities installed in 101 accelerating modules. Before assembly into modules the cavities are tested in a dedicated test facilities. The testing procedures are prepared based on DESY expertise and available software from Tesla Test Facility (TTF) Collaboration and Free electron LASer for Hamburg (FLASH). RF test provides the most important information about cavity performance: maximum available gradient and dependence of quality factor and radiation on the gradient. Results of the RF test determine, whether a cavity is shipped to CEA Saclay (France) to be assembled into a module or send for retreatment to improve its performance. In this paper we present the most important aspects of the cavity RF test procedure.
