    Extract HTTP info from integration tests to create Swagger docs▲9

    https://github.com/lazywithclass/swaggins It works by looking at the request and extracting the relevant information to populate the Swagger JSON file. I've wrote it to go with contract testing (http://martinfowler.com/articles/microservice-testing/#testing-contract-introduction), but it can also work with normal HTTP based integration tests. Any suggestion / opinion is welcome.
