5 运行测试

认证，下载相关的db文件到database

 mkdir $HOME/my_project/build/Integration/databasecd $HOME/my_project/source/avs-device-sdk/tools/Installsudo bash genConfig.sh config.json 12345 \$HOME/my_project/build/Integration/database \$HOME/my_project/source/avs-device-sdk \$HOME/my_project/build/Integration/AlexaClientSDKConfig.json \-DSDK_CONFIG_MANUFACTURER_NAME="my_project" \-DSDK_CONFIG_DEVICE_DESCRIPTION="ubuntu"

拷贝挂载运行，查看log看还有什么报错需要解决。
