Although this approach doesn’t get rid of step definition methods, it simplifies tests from a different, sort of the opposite, perspective of what I introduced in the previous section. Instead of implementing your tests in Gherkin or similar files, and having to bother with step definition implementations, you implement tests as actual code in a Gherkin-like DSL (Domain Specific Language). This way you don’t have to touch any actual Gherkin file. That is what the JGiven framework aims to achieve, or at least how it fits into the topic of this article.
