由 痴心易碎 提交于 2020-01-25 10:04:21

问题 I'm setting up an integration test to determine if a program that publishes a message to SNS is working correctly. The published message includes a few critical message attributes that I need to check in order to determine correctness. So far, I have set up a simple HTTP server that acts as an SNS subscriber.
