I'm handling a code repository that is responsible to deploy / install / upgrade agent that are running on different platform, windows, unix, linux.
The code base already has some unit test to cover the behavior of important component.
I'm now thinking how I could increase the test coverage and confidence of the setup / upgrade by introducing integration testing, and integrate with travis.
What are the available test framework that I could explore on this type of application?
===== Edit #1 =====
The application I'm looking at implementing integration testing as the follow characteristic.
- The code base is written in ruby.
- It is a setup / installer, the main functionality to bring the state of the machine to a desired stated. For example, we would deploy a file, set the file permission or managed the content of the file if the Shasum does not match.
- Most of the codes are platform dependent, and create other processes to perform the job. For example chmod.
- It calls external remote APIs, to fetch and verify configuration / data.
Is there any best practice, or code base out there that does this kind of integration testing?
