Cucumber
Cucumber is a behavior-driven development (BDD) tool that allows developers, testers, and business stakeholders to collaborate on software specifications using plain language. It enables the creation of executable specifications written in Gherkin, a domain-specific language that describes software behavior in a human-readable format. These specifications can be automated as tests to ensure the software meets the defined requirements.
Developers should learn Cucumber when working on projects that require clear communication between technical and non-technical teams, as it bridges the gap by using natural language for test scenarios. It is particularly useful in agile environments for defining acceptance criteria, automating end-to-end tests, and ensuring that software features align with business goals. Common use cases include web application testing, API testing, and integration testing where behavior-driven approaches are prioritized.
