Summary 9 SRF modules (including one 3.9 GHz module) tested until now on the Cryo Module Test Bench (CMTB) at DESY. XFEL Accelerating Module Test Facility (AMTF) is under construction. 7 superconducting accelerating modules are used now in the FLASH LINAC at DESY. 3 modules were tested at FLASH and 4 modules were tested at CMTB facility. FLASH linac reached 1.3 GeV goal. First three XFEL prototype modules PXFEL1,2,3 were tested at module test stand CMTB at DESY. Coupler and cavity conditioning procedure was done with PXFEL modules. In PXFEL1 cavities gradients from 27 to 36 MV/m are reached, module operation with average gradient of 30 MV/m using tailored RF power distribution is possible. PXFEL1 is used in FLASH (ACC7). PXFEL2 and PXFEL3 modules suffered from some cavities degradation and will be reassembled. Module 3***, ACC1@FLASH was tested in-situ in the linac and did reach its operating gradient goal.
