Claim 15:
16. The test method according to claim 15, further comprising:
applying a break-over voltage between the anode and the cathode of each test device to make each test device turned on, generating, by the anode and the cathode, an external current under an action of the break-over voltage, detecting the external current of each test device and drawing a relationship curve of the external current and the break-over voltage;
determining the optimal value of the variable parameter according to the second internal current and the external current; and
when the test voltage is the same as the break-over voltage, if a difference value between the second internal current and the external current is less than a preset value, determining a value of the variable parameter of the corresponding test device as the optimal value.
