Disclosed are systems and methods for pressure testing coiled tubing (CT) in a well. A CT pressure testing device may include a CT connector for attaching to a CT segment and a pressure test housing defining a pressure chamber. A rod may extend through a top opening of the pressure test housing and through the CT connector to the severed end of the CT segment. A sealing plug coupled to a bottom end of the rod may create an interface between the CT connector and the CT segment. A force activator may apply a force to a top end of the rod, causing the rod to push the sealing plug into the CT segment and tighten the interface. A pump may pressurize the pressure chamber to perform a pressure test on the sealing plug. Accordingly, the CT pressure testing device may establish a well control barrier for the well.
