In the second episode of Serverless Office Hours, I show you how to use dependency injection and pointer receiver functions to unit test your AWS Lambda functions in Go. I also compare performance test results of initializing dependencies in your main function versus your Lambda handler function.

* (2:23) Creating a SAM app - docs.aws.amazon.com/serverles...
* (4:00) Anatomy of an AWS Lambda function in Go - docs.aws.amazon.com/lambda/la...
* (11:11) Receiver functions and dependency injection - tour.golang.org/methods/4
* (14:00) Writing unit tests
* (31:05) Initializing AWS resources in func main() vs. func handler()
