1. A refrigerator, comprising a microfluidic testing system used for qualitatively or quantitatively testing a preset test parameter of a sample liquid, the microfluidic testing system comprising:
a microfluidic biochip which is provided with a sample inlet, a communication port and a testing pool formed inside the microfluidic biochip, wherein the sample inlet, the testing pool and the communication port are in sequential communication by means of a micro-channel;
a chip mounting mechanism used for mounting the microfluidic biochip;
a sample liquid driving device in hermetic communication with the communication port, so as to promote the sample liquid in contact with the sample inlet to flow into the micro-channel and flow to the testing pool via the micro-channel;
a testing mechanism used for testing the testing pool to obtain the preset test parameter of the sample liquid;
a cabinet internally defining a storage space for storing articles; and
a door connected to the cabinet and used for opening and/or closing the storage space; and
wherein a microfluidic testing device is provided on the door.
