        Lambda: stubToLambda(paramsToExpect, PayloadToReturn, options)
        // you can extend the class to your class
        }

moduleUsingLambdaAWSClass //any call to lambda is mocked

// Class example

lambda = new StubToLambda(paramsToExpect, PayloadToReturn, options)

lambda.invoke(params, (err, data)=>{/***callback***/}) // or
lambda.invoke(params).promise() // return a promise
// if params is not equal to paramsToExpect throw a error
})
