Behavior testing using Go

Behavior testing or integration testing is a good method of implementing end-to-end black box testing. One popular framework for this type of testing is Cucumber (https://cucumber.io/), which uses the Gherkin language to describe the steps to a test in English, and then implements those steps in code. Go has a Cucumber library as well (github.com/DATA-DOG/godog). This recipe will use the godog package to write behavior tests.
