Gherkin
Gherkin is a business-readable, domain-specific language used for writing behavior-driven development (BDD) specifications. It provides a structured format to describe software behaviors in plain English using keywords like Given, When, Then, And, and But. This language is primarily used with tools like Cucumber to automate acceptance tests and bridge communication between technical and non-technical stakeholders.
Developers should learn Gherkin when working on projects that adopt behavior-driven development (BDD) or need clear, executable specifications for testing. It is particularly useful in agile teams to ensure requirements are well-understood and testable, reducing misunderstandings and improving collaboration between developers, testers, and business analysts. Use cases include defining acceptance criteria, automating end-to-end tests, and documenting system behaviors in a human-readable format.
