Fuubar


fuubar is an instafailing RSpec formatter that uses a progress bar instead of a string of letters and dots as feedback.

examples

Installation

gem install fuubar

# or in your Gemfile

gem 'fuubar'

Usage

In order to use fuubar, you have three options.

Option 1: Invoke It Manually Via The Command Line

rspec --format Fuubar --color

Option 2: Add It To Your Local .rspec File

# .rspec

--format Fuubar
--color

Option 3: Add It To Your spec_helper.rb

# spec/spec_helper.rb

RSpec.configure do |config|
  config.add_formatter 'Fuubar'
end

Advanced Usage

Customizing The Bar

fuubar exposes an RSpec configuration variable called fuubar_progress_bar_options which, when set will be passed directly to ruby-progressbar which does all the heavy lifting. Take a look at the ruby-progressbar documentation for details on all of the options you can pass in.

Example

Let's say for example that you would like to change the format of the bar. You would do that like so:

# spec/spec_helper.rb

RSpec.configure do |config|
  config.fuubar_progress_bar_options = { :format => 'My Fuubar! <%B> %p%% %a' }
end

would make it so that, when fuubar is output, it would look something like:

My Fuubar! <================================                  > 53.44% 00:12:31

Hiding Pending/Skipped Spec Summary

By default fuubar follows RSpec's lead and will dump out a summary of all of the pending specs in the suite once the test run is over. This is a good idea because the additional noise is a nudge to fix those tests. We realize however that not all teams have the luxury of implementing all of the pending specs and therefore fuubar gives you the option of supressing that summary.

Example

# spec/spec_helper.rb

RSpec.configure do |config|
  config.fuubar_output_pending_results = false
end

Enabling Auto-Refresh

By default fuubar refreshes the bar only between each spec. You can enable an auto-refresh feature that will keep refreshing the bar (and therefore the ETA) every second. You can enable the feature as follows:

# spec/spec_helper.rb

RSpec.configure do |config|
  config.fuubar_auto_refresh = true
end

Undesirable Effects

Unfortunately this option doesn't play well with things like debuggers, as having a bar show up every second would be undesireable (which is why the feature is disabled by default). Depending on what you are using, you may be given ways to work around this problem.

Pry

Pry provides hooks that can be used to disable fuubar during a debugging session, you could for example add the following to your spec helper:

# spec/spec_helper.rb

Pry.config.hooks.add_hook(:before_session, :disable_fuubar_auto_refresh) do |_output, _binding, _pry|
  RSpec.configuration.fuubar_auto_refresh = false
end

Pry.config.hooks.add_hook(:after_session, :restore_fuubar_auto_refresh) do |_output, _binding, _pry|
  RSpec.configuration.fuubar_auto_refresh = true
end
Byebug

Unfortunately byebug does not provide hooks, so your best bet is to disable auto-refresh manually before calling byebug.

RSpec.configuration.fuubar_auto_refresh = false
byebug

Security

fuubar is cryptographically signed. To be sure the gem you install hasn’t been tampered with, follow these steps:

  • Add my public key (if you haven’t already) as a trusted certificate

    gem cert --add <(curl -Ls https://raw.github.com/thekompanee/fuubar/master/certs/thekompanee.pem)
  • Install fuubar telling it to use security checks when possible.

    gem install fuubar -P MediumSecurity

Note: The MediumSecurity trust profile will verify signed gems, but allow the installation of unsigned dependencies.

This is necessary because fuubar has a dependency on RSpec which isn't signed, and therefore we cannot use HighSecurity, which requires signed gems.
