how to unit test aws lambda with SQS Event

Question

I am implementing a AWS Lambda that gets triggered from SQS, and then do some other thing. This is my current Handler:

how I can pass a fake SQSEvent to test my function?

public class Handler implements RequestHandler<SQSEvent, Void> {
    @Override
    public Void handleRequest(SQSEvent sqsEvent, Context context) {
        helper(sqsEvent.record);

        return null;
    }
}
