Emacs mode for editing plain text user stories



Copy all the files to ~/.emacs.d/elisp/feature-mode, for example, and add this to your .emacs to load the mode

(add-to-list 'load-path "~/.emacs.d/elisp/feature-mode")


feature-mode is available in both Marmalade and MELPA.

You can install it with the following command:

M-x package-install feature-mode

Optional configurations

Set default language if .feature doesn't have "# language: fi"

(setq feature-default-language "fi")

Point to cucumber languages.yml or gherkin i18n.yml to use exactly the same localization your cucumber uses

(setq feature-default-i18n-file "/path/to/gherkin/gem/i18n.yml")

Load feature-mode

(require 'feature-mode)
(add-to-list 'auto-mode-alist '("\.feature$" . feature-mode))

Point goto-step-definition capability to your step definitions

(setq feature-step-search-path "features/**/*steps.rb")
(setq feature-step-search-gems-path "gems/ruby/*/gems/*/**/*steps.rb")

The feature-step-search-gems-path variable points to where you have extra gems installed that have extra step definitions. For example, if you use bundler to install gems for your project and put them in a gems/ directory via:

bundle install --path ./gems

Key Bindings

In order to get goto-step-definition to work, you must install the ruby_parser gem (version 2.0.x) and gherkin (version 2.11.8). For example:

gem install ruby_parser --version "~> 2.0.5"
gem install gherkin --version 2.11.8
Keybinding Description
C-c ,v Verify all scenarios in the current buffer file.
C-c ,s Verify the scenario under the point in the current buffer.
C-c ,f Verify all features in project. (Available in feature and ruby files)
C-c ,r Repeat the last verification process.
C-c ,g Go to step-definition under point (requires ruby_parser gem >= 2.0.5)

Supported languages

At the moment, Cucumber.el supports whatever your Cucumber supports. Just configure it to load i18n.yml from your Gherkin gem sources.

Support for docker-compose

If the project path contains a docker-compose.yml file, Cucumber is executed through docker-compose.

The following variables can be set to change the behavior related too this:

Variable Type Description
feature-use-docker-compose boolean Use docker-compose when available
feature-docker-compose-command string The docker-compose command to execute
feature-docker-compose-container string Name of the container to start Cucumber in

Project Development / Maintenance

To run the tests in the source project, do the following:

gem install bundler
make test

You may have to use sudo to run the gem install command.
