What is Cucumber and how it works?

Cucumber is a BDD (Behavior Driven Development) tool for testing software. Used in conjunction with a test runner (such as JBehave or SpecFlow), Cucumber allows business stakeholders to define the expected behavior of software in plain text, which serves to document and capture requirements and also to provide automated tests that verify the behavior of the system under test. Cucumber offers an imperative yet natural way of writing scenarios that can be read by all stakeholders, regardless of technical background.
