Test your serverless application with AWS SAM

After writing and building your application, you will be ready to test your application to verify that it functions correctly. With the AWS SAM command line interface (CLI), you can locally test your serverless application before uploading it to the AWS Cloud. Testing your application helps you confirm the application’s functionality, reliability, and performance all while identifying issues (bugs) that will need to be addressed.

This section provides guidance on common practices you can follow to test your application. The topics in this section focus mostly on the local testing you can do before deploying in the AWS Cloud. Testing before deploying helps you identify issues proactively, reducing unnecessary costs associated with deployment issues. Each topic in this section describes a test you can perform, tells you the advantages of using it, and includes examples showing you how to perform the test. After testing your application, you’ll be ready to debug any issues you’ve found.
