Emacs RSpec Mode
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:
| Keybinding | Description |
|---|---|
C-c , v |
Verify the spec file associated with the current buffer |
C-c , a |
Run spec for entire project |
C-c , t |
Toggle back and forth between a spec and its target |
C-c , e |
Toggle back and forth between a method and its examples in the spec file |
C-c , 4 t |
Find in the other window the spec or the target file |
C-c , 4 e |
As above, but try to navigate to the example or method corresponding to point |
C-c , r |
Re-run the last verification process |
C-c , y |
Yank the last verification command to clipboard |
C-c , m |
Run all specs related to the current buffer |
C-c , c |
Run the current spec and all after it |
C-c , s |
Verify the example or method defined at point |
C-c , f |
Re-run just the failed examples from the last run |
RSpec mode
These keybindings are available in Ruby spec files:
| Keybinding | Description |
|---|---|
C-c , s |
Run the specified example at point |
C-c , d |
Toggle the pendingness of the example at point |
RSpec Dired mode
These keybindings are available in Dired buffers:
| Keybinding | Description |
|---|---|
C-c , v |
Run all specs in the current directory |
C-c , s |
Run marked specs or spec at point (works with directories too) |
C-c , a |
Run the 'spec' rake task for the project of the current file |
C-c , r |
Re-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:
| Option | Default value | Description |
|---|---|---|
rspec-use-docker-when-possible |
nil |
Enable docker |
rspec-docker-command |
docker-compose run |
Docker command to run |
rspec-docker-cwd |
/app/ |
Path rspec to run in inside of the container |
rspec-docker-container |
rspec-container-name |
Name 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)Contributing
