# Run contract tests from API descriptions against live endpoints before integrations break with Dredd

Lets an agent execute OpenAPI or API Blueprint contract checks against a running service so spec drift is caught before release.

## Prerequisites

Node.js, Dredd CLI, OpenAPI or API Blueprint spec, running API endpoint

## Installation

Use the upstream install or setup path that matches your environment:
- $ npm install -g dredd

Requirements and caveats from upstream:
- [Node.js (JavaScript)](https://dredd.org/en/latest/hooks-nodejs/)
- [Python](https://dredd.org/en/latest/hooks-python/)

Basic usage or getting-started notes:
- Create an [API Blueprint][] file called api-description.apib.
- Follow [tutorial at API Blueprint website][api blueprint tutorial]
- or just take one of the [ready-made examples][api blueprint examples].
