Example configuration files for Mountebank

Mountebank

Mountebank is the first open source tool to provide cross-platform, multi-protocol test double over the wire. Simply point your application under test to mountebank instead of the real dependency, and test like you would with traditional stubs and mocks.

Install Mountebank

cmd$ npm install -g mountebank@latest

Config Files

You can load your configuration files to Mountebank with an option --configfile It supports a set of complex configurations for multiple imposters using EJS templates, which allow you to put contents into separate files and use an EJS include directive to merge the contents into one file.

Personally, I recommend you to use Atom as an editor for EJS files. I also created Atom snippets for Mountebank which can help you to create your configuration files easier. You can copy the snippets.cson file into ~/.atom/ (You'll see an example usage below) Make sure that you've installed the language-ejs plugin into your Atom app.

Start Mountebank

cmd$ mb --configfile imposters.ejs --allowInjection

How to use snippets

Just copy the snippets.cson file into ~/.atom/ directory, then restart Atom.

cmd$ cp snippets.cson ~/.atom/
