## What it is
Cucumber is a testing tool that runs automated acceptance tests written in plain-language Gherkin syntax, supporting Behaviour-Driven Development (BDD). This is the JavaScript/TypeScript implementation for Node.js, part of a multi-language ecosystem including Ruby, Java, and Rails variants.

## Use cases
- write acceptance tests in plain language with gherkin
- run bdd scenarios for a node.js application
- collaborate with non-technical stakeholders on test specifications
- create executable specifications that double as documentation
- test web apps with cucumber and playwright
- run feature files in ci pipelines

## When to choose
- your team practices BDD and wants specs readable by business stakeholders
- you need acceptance tests in Gherkin on Node.js
- you want living documentation validated against actual system behavior

## When to avoid
- you only need fast unit tests without plain-language scenarios
- your team does not maintain Gherkin feature files
- you need testing in a language without a Cucumber implementation

## Facets

- function: testing, e2e-testing, cli
- domain: testing, developer-tools
- platform: cross-platform, cli
