Testing the function

Next, let's look at how can we test the newly created AWS Lambda function using the AWS Lambda Console. At this point, as we don't have any triggers defined for our AWS Lambda function, we will just use the AWS Lambda console to configure a test event and invoke our AWS Lambda function.
