Gherkin (Language)[edit]
Gherkin is the language that Cucumber uses to define test cases. It is designed to be non-technical and human readable, and collectively describes use cases relating to a software system.[9]

The purpose behind Gherkin's syntax is to promote Business Driven Development practices across an entire development team, including business analysts and managers.[10]

It seeks to enforce firm, unambiguous requirements starting in the initial phases of requirements definition by business management and in other stages of the development lifecycle.[10]

In addition to providing a script for automated testing, Gherkin's natural language syntax is designed to provide simple documentation of the code under test.[9] Gherkin currently supports keywords in dozens of languages.[9][11]

Александр, может, у Вас опечатка в термине?
Наверно, не Gerchin, а Gherkin? Или нет?
