1. A sealability testing apparatus, comprising a tester, wherein the tester comprises:
a leakage assembly having:
an upper cap provided with a fluid inlet and a pressure sensor on an upper end of the upper cap, wherein said pressure sensor is capable of recording and transmitting pressure data to a control panel by a pressure data wire;
a leakage element with different size of pores being secured into said upper cap for simulating downhole string leakage on-site;
a retainer being in connection with a lower end of said upper cap for fixing said leakage element; and
a visual bottom cup made of quartz glass, wherein a bottom of said visual bottom cup is open, and said visual bottom cup is temperature-resistant and pressure-resistant for observing a plugging process when sealant flows across said leakage element,
wherein the upper cap, the leakage element, the retainer and the visual bottom cup are arranged coaxially.
