Step S222, starting a timer with a certain time equal to the preset test time corresponding to the current test item; in specific implementation, the start timer (gps test timer) is used for monitoring the test time of the current test item, so that the test time is equal to the preset test time; for example, if the preset test duration of the current test item is 10min, the corresponding timer with the starting timing time equal to 10min controls the test time of the current test item.
Further, the step S230 specifically includes:
step B231, according to the preset test duration corresponding to the obtained current test item, carrying out the sensitivity attenuation test of the GPS on the current test item, and recording the test starting time; in specific implementation, the step of performing the sensitivity attenuation test of the GPS on the current test item includes: opening a GPS module, and acquiring the number of satellites in the current environment, the corresponding CNR signal-to-noise ratio average value, the CNR signal-to-noise ratio maximum value and the CNR signal-to-noise ratio minimum value, and the clock deviation average value, the CNR signal-to-noise ratio maximum value and the CNR signal-to-noise ratio minimum value of 26 MHZ; wherein, the starting test time is coordinated universal time (UTC time) of starting test.

In specific implementation, the GPS module is opened, the number of satellites in the current environment and the corresponding CNR signal-to-noise ratio average value, the maximum value and the minimum value are obtained, the obtained CNR signal-to-noise ratio average value and the previously obtained reference CNR signal-to-noise ratio value are subtracted, and if the obtained difference value (for example, 2db) is smaller than a preset CNR signal-to-noise ratio change threshold value (for example, 3db), the CNR signal-to-noise ratio test of the current test item is judged to be passed; otherwise, judging that interference exists, and recording the result.

In specific implementation, a GPS module is started, a clock signal average value is obtained and is subjected to difference calculation with a reference clock value obtained previously, and a 26MHZ clock deviation average value (difference value), a maximum value and a minimum value are obtained; if the obtained difference (for example, 0.5ppm) is smaller than a preset clock signal change threshold (for example, 1ppm), judging that the clock signal test of the current test item passes; otherwise, judging that interference exists, and recording the result.

In specific implementation, the CNR snr test and the clock signal test are respectively determined, and as long as one of the CNR snr test and the clock signal test determines that interference exists, the sensitivity attenuation test of the GPS of the current test item is determined as interference, that is, the test fails (fail), and when both of the CNR snr test and the clock signal test are determined as pass, the sensitivity attenuation test of the GPS of the current test item is determined as pass (pass). That is, in this embodiment, it is required to satisfy less than 3db and 1PPM respectively at the same time to determine that the test item test passes, otherwise, it is determined that there is interference, for example, if the obtained difference values are 1db and 2PPM respectively, the test item fails, and it is determined that there is interference.
In step S300, after all the test items are tested, the mobile phone automatically outputs the test result of each test item, so that the user can obtain the test result at one time.
Further, the step S300 specifically includes: and after all the test items are tested, automatically outputting a test result file containing the test serial number, the test time, the test item name and the test result of each test item, and outputting a corresponding performance parameter log file.
