Sendgrid-Mock

This docker allows mocking the real Sendgrid Rest Server.

Being specially useful when testing it speeds up mail automation, eliminating the need to poll for services like real email servers (gmail, etc.) or Mailinator.

TL;DR

docker run -d --name mailserver -p 3000:3000 tfsoares/sendgrid-mock

What to change on Sendgrid

This will store the sent email on memory, allowing the recipient to be searched.

The endpoint used is: POST http://<docker_gateway>/api/mail.send.json in place of the real service endpoint POST https://api.sendgrid.com/api/mail.send.json.

The configurations would be:

Node.js

require('sendgrid')(sendgrid_username, sendgrid_password, {
    "protocol":"http",
    "host": "<docker_gateway>",
    "port":3000 
});

Java

new SendGrid("SENDGRID USERNAME", "SENDGRID_PASSWORD")
    .setUrl("http://<docker_gateway>:3000");

Read Messages

This endpoint will allow knowing if an email sending has been requested.

Endpoint

GET http://<docker_gateway>:3000/api/mail.read.json/<email_to_search>

Response

{ "total": <how_may_mails>, "results": [<mails>] }

Clear messages

This will clear all cached emails. This can not be reversed.

Endpoint

GET http://<docker_gateway>:3000/api/mail.clear.json

Response

{ "message": "success", "errors": [] }

Run

To run this docker you will need to have Docker and installed. You can also just run the bash script build_and_run.sh.
