This code shows an example about how to test node.js modules that rely on the AWS SDK. It uses the AWS SDK MOCK library to do it.
An example module that could be a Lambda function or just an implementation
of the repository pattern can be found in src/caller.js.
You can find two tests, one success scenario and one failure scenario, in
the test/test-dynamo-with-aws-sdk-mock.js module.
After you clone the repository, restore the dependencies with
npm install
To run the tests, you can type
npx mocha
