Infrastructure testing helper for AWS Resources that uses AWS SSM to remotely execute commands on EC2 machines, to enable infrastructure engineering teams to write tests that validate behaviour.

ssm-tester allows infrastructure delivery teams to write tests that can execute custom commands on ec2 instances and hence validate for otherwise hard to test behaviour.

When teams write infrastructure as code - they should not only test against the correct configuration, but also test the infrastructure for behaviour! Specially when writing infrastructure code in a declarative tooling like terraform, tests that validate configuration may have limited value. For example, validating for configuration:

These tests may essentially be a repeat of the configuration specified in our Infrastructure declarative code and do not validate the behaviour we want to guarantee in our infrastructure. Instead it would be better if we could write tests to validate behaviour:

ssm-tester enables users to write automated tests that validate behaviour, so infrastructure engineering teams do not have to wait for application teams to report broken infrastructure, or worse, wait for incidents in production.
