Our team is building an aws product which uses several set 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 an integration testing on these services. For an example integration of two lambdas and how they perform when they are integrated. I did a 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.
