"""Generate Android.mk, Android.bp, and AndroidTest.xml files for given hal

Usage:
  python launch_hal_test.py [--options] hal_package name

  where options are:
  --test_type: Test type, currently support two types: target and host.
  --time_out: Timeout for the test, default is 1m.
  --package_root: Prefix of the HAL package. default is android.hardware
  --path_root: Root path that stores the HAL definition. default is hardware/interfaces
  --test_binary_file: Test binary file for target-side HAL test.
  --test_script_file: Test script file for host-side HAL test.
  --test_config_dir: Directory path to store the test configure files.
  --replay: Whether this is a replay test.
  --disable_stop_runtime: Whether to stop framework before the test.
Example:
  python launch_hal_test.py android.hardware.nfc@1.0
  python launch_hal_test.py --test_type=host --time_out=5m android.hardware.nfc@1.0
  python launch_hal_test.py --package_root com.qualcomm.qti
  --path_root vendor/qcom/proprietary/interfaces/com/qualcomm/qti/
  --test_configure_dir temp/ com.qualcomm.qti.qcril.qcrilhook@1.0
