Our team is building an AWS product which uses several sets of tools like Lambda, SNS topics, EC2, data pipelines etc. I would like to know what type of testing tools/strategies that can be used to perform integration testing on these services. For an example integration of two lambdas and how they perform when they are integrated. I did an R&D and found out that for unit testing we can use AWS toolkit plugin in Eclipse but that covers only the unit testing. I want to perform an integration testing on this. Your answers are highly appreciated.
