Emacs RSpec Mode

CI

RSpec mode provides some convenience functions for dealing with RSpec.

Installation

You can install via ELPA, or manually by downloading rspec-mode and adding the following to your init file:

(add-to-list 'load-path "/path/to/rspec-mode")
(require 'rspec-mode)

Provided you have yasnippet installed, you can load the snippets:

(eval-after-load 'rspec-mode
 '(rspec-install-snippets))

(This isn't done automatically to avoid conflicts with snippets you may already have set up.)

Usage

If rspec-mode is installed properly, it will be started automatically when ruby-mode is started.

RSpec Verifiable mode

These keybindings are available in any Ruby source file:

KeybindingDescription
C-c , vVerify the spec file associated with the current buffer
C-c , aRun spec for entire project
C-c , tToggle back and forth between a spec and its target
C-c , eToggle back and forth between a method and its examples in the spec file
C-c , 4 tFind in the other window the spec or the target file
C-c , 4 eAs above, but try to navigate to the example or method corresponding to point
C-c , rRe-run the last verification process
C-c , yYank the last verification command to clipboard
C-c , mRun all specs related to the current buffer
C-c , cRun the current spec and all after it
C-c , sVerify the example or method defined at point
C-c , fRe-run just the failed examples from the last run

RSpec mode

These keybindings are available in Ruby spec files:

KeybindingDescription
C-c , sRun the specified example at point
C-c , dToggle the pendingness of the example at point

RSpec Dired mode

These keybindings are available in Dired buffers:

KeybindingDescription
C-c , vRun all specs in the current directory
C-c , sRun marked specs or spec at point (works with directories too)
C-c , aRun the 'spec' rake task for the project of the current file
C-c , rRe-run the last RSpec invocation

See rspec-mode.el for further usage.

Hooks

Any functions in rspec-before-verification-hook will be executed before the verification (rspec-verify) and variants.

Any functions in rspec-after-verification-hook will be executed after the verification (rspec-verify) and variants. The hook will be executed whatever the outcome of the verification.

Gotchas

Debugging

To use binding.pry or byebug, install inf-ruby and add this to your init file:

(add-hook 'after-init-hook 'inf-ruby-switch-setup)

When you've hit the breakpoint, hit C-x C-q to enable inf-ruby.

RVM

If you use RVM, you may have to set rspec-use-rvm to true to make rspec-mode function properly:

(setq rspec-use-rvm t)

Or set it using Emacs' customization system.

ZSH and RVM

If you use ZSH and RVM, you may encounter problems running the specs. It may be so that an older version of Ruby, than the one you specified in .rvmrc, is used. This is because ZSH runs a small script each time a shell is created, which modifies the $PATH. The problem is that it prepends some default paths, such as /usr/bin, which contains another ruby binary.

What you can do to solve this is to use BASH for running the specs. This piece of code does the job:

(defadvice rspec-compile (around rspec-compile-around)
  "Use BASH shell for running the specs because of ZSH issues."
  (let ((shell-file-name "/bin/bash"))
    ad-do-it))

(ad-activate 'rspec-compile)

Vagrant

You can run specs inside a Vagrant box. You can enable it through the rspec-use-vagrant-when-possible customization option. You can also set the directory where your project is inside your box through the rspec-vagrant-cwd option. This will run specs through the vagrant ssh -c 'cd <cwd>; <rspec command>'.

Docker

You can run specs inside a Docker container. This can be enabled through the rspec-use-docker-when-possible option. This enabled, rspec is executed through docker-compose run. The following customization options are available:

OptionDefault valueDescription
rspec-use-docker-when-possiblenilEnable docker
rspec-docker-commanddocker-compose runDocker command to run
rspec-docker-cwd/app/Path rspec to run in inside of the container
rspec-docker-containerrspec-container-nameName of the container to run rspec into

To define the options for different projects, have a look at Per-Directory Local Variables.

Auto-scrolling

Set compilation-scroll-output. For example, (setq compilation-scroll-output t) will turn on auto scrolling.

Multiple Compilation Buffer Support

RSpec Mode can support running multiple RSpec compilation buffers concurrently with the rspec-allow-multiple-compilation-buffers option. To turn this on:

(setq rspec-allow-multiple-compilation-buffers t)
