aws-sns-mock-test

it's sample project to understand how mock works with aws. Example with SNS.

Purpose

Succeed to make sure that the sns message is sent with specific parameter by calling snsService.publishMessage()

Installation

run : npm install

Folder /succeed

/succeed/method1

In this case, we import SNS by import { SNS } from 'aws-sdk'; That works as expected.

run:

npm run test-succeed

/succeed/method2

The implementation in /succeed/method2 fixes the failure/method1.test.js by using import SNS from 'aws-sdk/clients/sns'; https://stackoverflow.com/a/64404039/11465286

Folder /failure

In this case, we import SNS by import SNS from 'aws-sdk/clients/sns'; Impossible to make it work.

Two ways to test it :

• Method1 : By just using jest. (Fixed by https://stackoverflow.com/a/64404039/11465286, see ./succeed/method2)
• Method2 : By using a third lib, called jest-aws-sdk-mock

run:

npm run test-failure
