Testing in Mantil Project
Your API's in Mantil are pure Go code. They don't have anything AWS or Lambda
specific. Mantil provides all infrastructure burden. Unit testing you API'a are
like unit testing any other Go struct.
Our example project ping also provides example of a trivial API test. It is there to show the idea of where and how to unit test API's.
Integration tests are the category of tests that depend on some other outside resources. In the other example project, excuses, we have examples of both unit and integration tests. In unit we are mocking outside service with in process HTTP server. And in integration we are using real URL from the internet. So holding your integration tests side-by-side with the unit or moving them to another place are both valid options. It really depends on project.
End to end tests
Mantil project holds end to end tests in
/test folder (from the project root).
is an example of an end to end test for our ping project. You can run it with the
mantil test. It uses the current project stage to run HTTP request against
httpexpect is a great library for quickly building requests and examining HTTP responses.
