| Audience | The project says thousands of companies rely on Cucumber tests to validate their software. | The guide describes Node-Tap as a framework for writing tests and a CLI for running tests and managing plugins, watching code changes, and analyzing coverage. |
| Installation | The documentation shows installing `@cucumber/cucumber` as a development dependency with npm or Yarn. | The getting-started guide installs it with `npm install tap --save-dev`. |
| Integrations | Cucumber says it is not a browser automation tool, but works with browser automation tools such as Selenium WebDriver. | The repository lists optional plugins for Nock, Sinon, and esbuild-kit. |
| Purpose | Cucumber reads executable specifications written in plain text and checks whether software conforms to them, reporting success or failure for each scenario. | Node-Tap is a Test-Anything-Protocol test framework library for JavaScript and a command-line tool for running tests. |
| Reporting | Cucumber uses reporter plugins to produce reports showing which scenarios passed or failed, including built-in, separately installed, and custom plugins. | The project describes TAP output as machine-parseable and human-intelligible, and says reporter colors are tested for several forms of color vision deficiency. |
| Security | The project says it has a security policy that explains how to contact maintainers about security issues. | The product homepage and guide opened do not state security certifications or compliance standards. |
| Support | The FAQ directs users with questions to the Cucumber community and lists Cucumber School online training for deeper learning. | The site links to a Matrix chat for community discussion and GitHub for the project repository. |

In their own words
Cucumber.js
Cucumber.js checks software against executable specifications written as plain-text scenarios, reporting whether each scenario passes or fails. It is the JavaScript implementation of Cucumber and runs on Node.js. Scenarios use Gherkin syntax and are usually kept in `.feature` files alongside the software in source control. Step definitions connect each Gherkin step to code that carries out its described action; expressions can use Cucumber Expressions or regular expressions, but not both syntaxes in a single expression.
The tool runs feature files from the command line and can run in continuous integration, including parallel execution. Reporter plugins can produce results, and reports can be published to Cucumber Reports with `--publish`. Published reports are public and deleted after 24 hours. Cucumber.js is available as the `@cucumber/cucumber` npm module, installed as a development dependency with npm or Yarn. The setup requires Node.js and one of those package managers. It is free and open source, with Linux, macOS, Windows, and self-hosted platforms listed. It works with browser automation tools, but is not itself one.
