+Feature: using Guard API
+
+  In order to reuse existing Guard functionality
+  As a user
+  I want to call Guard API without Guard
+
+  Background: Guard is installed through bundler
+    Given my Gemfile includes "gem 'rake'"
+    And Guard is bundled using source
+
+  @spawn
+  Scenario: Call notifier
+    Given my Rakefile contains:
+    """
+    require "bundler/setup"
+    require "guard/notifier"
+    task :default do
+      Guard::Notifier.notify "foo", title: "bar"
+    end
+
+    """
+    Given I run `bundle exec rake`
+    Then the output should match /\[bar\] foo/
