# Test and validate

Before deploying sensors in production, you must calibrate them for accuracy, verify that they're correctly configured, and validate driver behavior under real operating conditions. This section provides the complete post-development validation workflow from calibration through stress testing and troubleshooting.

  <Card title="Calibrate sensors" href="./calibrate">
    Factory and runtime calibration procedures for accelerometer, gyroscope, magnetometer, proximity, and ambient light sensors.
  </Card>

  <Card title="Verify sensors" href="./verify">
    Use `ssc_sensor_info` to list all QSH-supported sensors and inspect their attributes. Confirms that the sensor registry is correctly parsed and that QSH is operational on the device.
  </Card>

  <Card title="Troubleshoot sensors" href="./test_troubleshoot">
    Diagnose and resolve the three most common sensor failures: `ssc_sensor_info` unable to list sensors, SUID lookup failures, and sensor listed but no data received.
  </Card>

  <Card title="Sensor testing tools" href="./test_tools">
    All testing and diagnostic tools: `ssc_sensor_info`, `ssc_drva_test`, `see_workhorse`, Hexagon DSP toolchain, and QXDM Professional for aDSP-side diagnostic logging.
