Dredd is a language-agnostic command-line tool for validating API documentation written in API Blueprint format against its backend implementation.

• Documentation
• Changelog
• Contributor's Guidelines

Dredd reads your API description and step by step validates whether your API implementation replies with responses as they are described in the documentation.

Dredd supports writing hooks — a glue code for each test setup and teardown.

Following languages are supported:

• Go
• Node.js (JavaScript)
• Perl
• PHP
• Python
• Ruby
• Didn't find your favorite language? Add a new one!

• Travis CI
• CircleCI
• Jenkins
• ...and any other *nix based CI!

$ npm install -g dredd

Note: Dredd works smoothly with Node.js 5, 4, 0.12, 0.10, and io.js v2.5.
