Unit test in businessLogic in express using sinon/aws-sdk-mock(for mock the DB : "DynamoDB") , mocha, and chai

[Fahrizal Septrianto]

Hi all, im new for using a unit testing inside my project. Does anyone here can guide me to create a unit testing in express for businessLogic layer. Im using aws dynamoDB for database. Im really confused how to mock the DB itself and then injected it to my businessLogic.

Thankyou appreciate
