Unit Test your Java Lambda functions

Unit testing is a vital part of the software development life cycle. Providing fast feedback to developers to ensure your business logic is working as it should be is essential for a productive workflow.

Building single purpose Lambda functions can require a shift in thinking for developers. Nowhere more so than with testing. As a general rule of thumb, unit test your business logic locally and test everything else in the cloud.

In this video, you will learn how to apply good testing practices and debug locally when building serverless Java applications with AWS Lambda & AWS SAM.
