Integration tests are tests that verify the integration between different components or systems. In the context of infrastructure as code (IAC), integration tests can be used to verify the correctness and correctness of the IAC code, as well as the resulting infrastructure that is deployed.
Here are a few examples of integration tests that you can run for your IAC code:
-
End-to-end tests: These tests verify the complete workflow of your IAC code, from the initial infrastructure deployment to the final configuration of the resources. End-to-end tests can be used to ensure that all components of your infrastructure are properly configured and working together.
-
Functional tests: These tests verify that specific functionality of your IAC code is working as expected. For example, you can write functional tests to verify that a particular resource is being created with the correct properties, or that a particular configuration is being applied to a resource.
-
Regression tests: These tests are used to verify that changes to your IAC code do not break existing functionality. For example, you can write regression tests to verify that a change to your IAC code does not cause any resources to be deleted or modified unexpectedly.
-
Performance tests: These tests are used to verify that your IAC code and infrastructure can handle the expected load and performance requirements. You can use performance tests to verify that your infrastructure can scale up or down as needed, and that it can handle high levels of traffic or resource usage.
-
Security tests: These tests are used to verify that your IAC code and infrastructure are secure and compliant with any relevant security standards or regulations. You can use security tests to verify that your infrastructure is configured with appropriate security controls, such as network security groups, firewalls, and access controls.
