How to Test

Get the code
Run a telemetry simulation with a custom "Template" environment variable set.

docker run -it -e "IotHubConnectionString=xxx" -e DeviceList="sim000001,sim000002" -e Template="{ \"deviceId\": \"$.DeviceId\", \"temp\": \"$.Temp\" }" -e Variables="[ { \"name\": \"Temp\", \"random\": true, \"max\": 25, \"min\": 23 }, { \"name\": \"Counter\", \"min\": 100 } ]" iottelemetrysimulator/azureiot-telemetrysimulator:latest
