Command-line Interface

Usage

$ dredd '<api-description-document>' '<api-location>' [OPTIONS]

Example:

$ dredd ./apiary.md http://127.0.0.1:3000

Arguments

api-description-document: URL or path to the API description document (API Blueprint, OpenAPI 2). Sample values: ./api-blueprint.apib, ./openapi2.yml, ./openapi2.json, http://example.com/api-blueprint.apib

api-location: URL, the root address of your API. Sample values: http://127.0.0.1:3000, http://api.example.com

Configuration File

If you use Dredd repeatedly within a single project, the preferred way to run it is to first persist your configuration in a dredd.yml file. With the file in place you can then run Dredd every time simply just by:

$ dredd

Dredd offers interactive wizard to setup your dredd.yml file:

$ dredd init

See below how sample configuration file could look like. The structure is the same as of the Dredd Class configuration object.

reporter: apiary
custom:
  - "apiaryApiKey:yourSecretApiaryAPiKey"
  - "apiaryApiName:apiName"
dry-run: null
hookfiles: "dreddhooks.js"
server: rails server
server-wait: 3
init: false
names: false
only: []
output: []
header: []
sorted: false
user: null
inline-errors: false
details: false
method: []
loglevel: warning
path: []
blueprint: api-description.apib
endpoint: "http://127.0.0.1:3000"

Note

Do not get confused by Dredd using a keyword blueprint also for paths to OpenAPI 2 documents. This is for historical reasons and will be changed in the future.
