The assembly of the series Spoke and Elliptical cryomodules is currently ongoing at CEA and IPNO, the test activities on the cryomodule prototypes have been completed and the series testing has started at the ESS testing facilities FREIA in Uppsala and Test Stand 2 at Lund. Status of the cavity fabrication and testing will be summarized. The experience of the commissioning of the testing facilities and the first results obtained on the series modules is presented and analyzed with respect to the vertical tests. For the elliptical cryomodules the TS2 results are compared with the CEA tests performed on the first three cryomodules of the series. PB - JACoW Publishing CP - Geneva, Switzerland ER -
