FactoryTest is used for manufacturing tests on Android devices. Includes: WiFi, Bluetooth, Ethernet, Mobile Network and more tests. Based on the function combination supported by different products, some items also support parameter configuration, which can be fully adapted to various products. After the test is complete, test results can be exported as files for analysis.

In order to flexibly adapt to various products, the APP supports configuration files to configure function combinations and test parameters. The configuration method is as follows:

1. Create a configuration file (factory_test_config.json).
2. Edit a configuration file by referring to the following text:

[
  {"key": "info", "param": ""},
  {"key": "wifi", "param": ""},
  {"key": "bt", "param": ""},
  {"key": "eth", "param": ""},

  {"key": "human", "param": ""},
  {"key": "acc", "param": ""},
  {"key": "display", "param": ""},

  {"key": "spk", "param": ""},
  {"key": "mic", "param": ""},
  {"key": "micarray", "param": "{'card':0, 'device': 1, 'channels': 4, 'rate':16000, 'bits':16, 'period_size':1024, 'period_cnt':3, 'play_channel':0}"},
  {"key": "key", "param": "[{'name':'BACK', 'code': 4, 'state': 0}, {'name':'MENU', 'code': 82, 'state': 0}, {'name':'MUTE', 'code': 164, 'state': 0}, {'name':'VOL+', 'code': 24, 'state': 0}, {'name':'VOL-', 'code': 25, 'state': 0}]"},
  {"key": "camera", "param": ""},
  {"key": "backlight", "param": ""},

  {"key": "sd", "param": ""},
  {"key": "gpio", "param": ""},
  {"key": "wiegand", "param": "{'write': {'format': 26, 'value': 7825015}, 'read': {'format': 26, 'value': 0}}"},
  {"key": "nd01", "param": "{'i2c': 1, 'calibrate': true}"},
  {"key": "pwm", "param": "[{'name': 'LED', 'pwm': 0, 'period': 10000, 'duty': 1000, 'state': 0}, {'name': 'Motor', 'pwm': 1, 'period': 10000, 'duty': 1000, 'state': 0}, {'name': 'Buzzer', 'pwm': 2, 'period': 10000, 'duty': 1000, 'state': 0}]"},
  {"key": "led", "param": "[{'name': 'RED', 'device': 'led_r', 'brightness': 1000, 'state': 0}, {'name': 'GREEN', 'device': 'led_g', 'brightness': 1000, 'state': 0}, {'name': 'BLUE', 'device': 'led_b', 'brightness': 1000, 'state': 0}]"}
]

3. Add the configuration file to /vendor directory to complete the configuration.

The configuration file consists of a Json array containing several Json items, each in the following format:

{"key": "key", "param": "paramter"}

• key: keyword (note: Must be supported for keyword.)
