Mocking library for testing AWS Lambda events by creating realistic events that contain dynamic data.
- Easy to use builder-pattern to create mock lambda events for testing
- Works with lambda-tester
- Works with Node 8.x
Install via npm.
npm install lambda-event-mock --save-dev
The following example code creates an s3 lambda event for the object
picture1.gif in the my-bucket-uploaded-pictures bucket.
const lambdaEventMock = require( 'lambda-event-mock' );
let myMock = lambdaEventMock.s3()
.object( 'picture1.gif' )
.bucket( 'my-bucket-uploaded-pictures' )
.build();
// myMock contains an s3 event object:
/*

"eventName": "ObjectCreated:Put",
"userIdentity": {
"principalId": "USER"
},

}
]
}
*/Note that lambda-event-mock fills in the time, date, and other properties of
the event to create a realistic looking event.
Note: Documentation is incomplete
lambda-event-mock supports the following lambda events:
