  6. 6. The WiFi capability test system according to claim 5, wherein the roaming capability test comprises the steps of:
    the test unit sets the same parameters for the first terminal simulator and the second terminal simulator, and adjusts the second program-controlled attenuator to an attenuation preset value D;
    then controlling attenuation values of the first program-controlled attenuator and the second program-controlled attenuator, gradually increasing the signal attenuation value of the first program-controlled attenuator, and gradually reducing the signal attenuation value of the second program-controlled attenuator; and after the WiFi equipment to be tested is disconnected with the first terminal simulator and is connected with the second terminal simulator, acquiring roaming jump time parameters and roaming success rate parameters.
  7. 7. The WiFi performance test system according to claim 1, wherein the direction of the controllable rotating table is adjusted to perform transmission performance tests of different angles for WiFi devices to be tested.
  8. A WiFi performance testing method applied to a WiFi performance testing system according to any one of claims 1 to 7, comprising the steps of:
    step one: equidistant placement or fixation of a plurality of WiFi devices to be tested on the periphery side of the controllable rotating table, and placement of the test module in the center of the controllable rotating table;
    step two: after the WiFi equipment to be tested and a router successfully establish the Wifi connection, acquiring address information distributed by the router for the WiFi equipment to be tested, and broadcasting the address information;
    step three: after receiving address information broadcast by the WiFi equipment to be tested, the test module establishes communication connection with the WiFi equipment to be tested according to the received address information;
    then, a testing module runs a preset performance testing program to test the performance of the WiFi equipment to be tested based on the established communication connection;
    step four: in the test process, a signal analysis module is used for collecting noise signals of a test module in real time and analyzing signal influence indexes Ys;
    if yes is larger than a preset influence threshold, generating a communication abnormal signal to the upper computer; to remind the manager that the current noise signal is seriously interfered, and to recommend to deal with as soon as possible;
    step five: the test module is used for recording the performance test data generated in the performance test process and generating a test report according to the recorded performance test data after the test is finished;
    comparing the performance test data in the test report with preset standard data to obtain a test result; and feeding back the test result to the upper computer for data presentation.
