notifications-sms-provider-stub

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.

Setting up

Install go

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

environment.sh (optional)

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 target the ECS apps by setting the ECS header, you can give the USE_ECS_APPS environment variable a value of "true":

export USE_ECS_APPS="true"

To run the application

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 deploy the application

How to make the API use this email provider stub

To turn it on for an app running in the PaaS use:

cf set-env APP-NAME FIRETEXT_URL http://notify-sms-provider-stub-staging.apps.internal:8080/firetext
cf set-env APP-NAME MMG_URL http://notify-sms-provider-stub-staging.apps.internal:8080/mmg
cf restage APP-NAME

and equivalent for other providers. The environment variables will remain set even if you redeploy the app.
