Testing Cloud Applications Without Breaking the Bank: Testcontainers and LocalStack

Nowadays, so many applications rely on cloud services, like databases, message queues, and file storage, from platforms like AWS, Google Cloud, and Azure. Those cloud services can bring some extra costs and complexity in terms of testing those cloud applications. The challenges include teams relying on mocks to test the application locally and in CI/CD, and extra costs to create test environments that use real services. However, a good alternative to deal with that is to use emulation tools to simulate those cloud services, providing a good confidence and saving a lot of costs.

How do you test an application that relies heavily on cloud services? Do you have a specific strategy for testing it, or do you simply run your tests regardless of the infrastructure costs? Testing cloud applications doesn’t have to break the bank—or your sanity. With tools like Testcontainers and LocalStack (free and open-source tools), you can create robust and realistic tests that mimic production cloud services, all without costly infrastructure or complex setups. In this talk, you will have actionable insights on how to optimize your testing process and lower your infrastructure costs.
