The invention provides a continuity testing method of cement mortar for 3D (Three Dimensional) printing of a building. A device for the continuity testing method is vertically arranged and comprises apushing rod (1) in an extruding barrel and a rear cover (6) which sleeves the pushing rod (1), wherein the pushing rod (1) is pushed into the extruding barrel (2); a gasket (5) is put into the extruding barrel (2) before the pushing rod (1) is put; the rear cover (6) is fixed at the upper end of the extruding barrel (2); the extruding barrel (2) is fixed on a fixed bracket (4); a straight ruler (3) is fixed on the fixed bracket (4); a zero scale line of the straight ruler (3) and the lower end of an extruding nozzle of the extruding barrel are located on the same horizontal line. Compared with the prior art, the cement mortar for the 3D printing of the building is tested and a quantification numerical value index related to continuity performance can be obtained; the continuity of the mortar for the 3D printing i
