This is a simple Go server that can be used as a stub for Notify SMS providers during a load test or when running the application locally. It accepts the requests for a notification, prints the message contents, returns an HTTP response and after a short delay sends a callback to a pre-configured URL.

You need a Go compiler to build the binary (brew install go).

You can tweak the configuration using the following variables.

echo "
export PORT=6300  # server port

export MMG_MIN_DELAY_MS=100  # min delay before callback is sent in ms
export MMG_MAX_DELAY_MS=1000 # max delay before callback is sent in ms
export MMG_CALLBACK_URL='http://localhost:6011/notifications/sms/mmg'

# similarly for each other provider
"> environment.sh

To build and run the server locally:

make run

This will start a server on port 6300, configured to send the callbacks to a local Notify API. To configure Notify API to use the server instead of actual MMG and Firetext set the environment.sh variables in the Notify API:

export MMG_URL='http://localhost:6300/mmg'

# similarly for each other provider

To turn it on for an app running ensure you set the following environment variables:

FIRETEXT_URL=http://notify-sms-provider-stub-staging.apps.internal:8080/firetext MMG_URL=http://notify-sms-provider-stub-staging.apps.internal:8080/mmg
