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
