This is particularly useful, if TDD strategy is used for incremental tests development along a happy path. In terms of BDD this is OK, but in terms of testing a step, definitions should be created so tests can actually be executed. Step definitions should not be exposed as an API but rather as an explicit translation map, a You have the code under test, the cucumber scenario, and your cucumber steps. The step definitions serve Cucumber as a translation of the steps we write in actions to execute to interact with the system. It also formalizes the Test-Driven Development best practices, in particular, the perspective of working from the outside-in.

This is where we will define exactly what to do with each of our steps. So if you are looking for a way to start packaging up those step definitions that you have used on multiple projects and are tired of copying across projects, check out how the Aruba gem does it and go from there. Just like Feature Files, WebDriverIO expects to find our Step Definitions in a specific location. Adding Step Definitions Luckily, Cucumber.js provides some helpful messages. In Cucumber-js calling steps from step definitions is not supported; this is by design. In my previous post, I demonstrated how I use CucumberJS - the JavaScript port of the Cucumber BDD testing tool - in developing Test-Driven code.

We need to add some code. Definition function wrapper If you would like to wrap step or hook definitions in with some additional logic you can use setDefinitionFunctionWrapper(fn).. Step definitions connect Gherkin steps to programming code. I walked through going from a failing feature with two scenarios to a passing cuke, while taking care to only add enough code that would make the assertions pass and refactoring as I went along under the assurance of a test harness.
