Behavior testing using Go

Behavior testing or integration testing is a good method of performing 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 implement those steps in code. Go has a cucumber library as well (github.com/DATA-DOG/godog). This recipe will explore using godog package to write behavior tests.

Getting ready

Configure your environment according to these steps:

Refer to the Getting ready section of the Mocking using the standard library recipe of this chapter.
Run the go get github.com/DATA-DOG/godog command.
Run the go get github.com/DATA-DOG/godog/cmd/godog command.

How to do it...

These steps cover writing and running your application:

From your terminal/console application, create the chapter8/bdd directory and navigate to it.
Copy tests from https://github.com/agtorre/go-cookbook/tree/master/chapter8/bdd or use this as an exercise to...
