  1Feature: Backtrace cleaning
  2
  3  To aid in diagnozing spec failures, RSpec cleans matching lines from backtraces. The default patterns cleaned are:
  4
  5    /\/lib\d*\/ruby\//,
  6    /org\/jruby\//,
  7    /bin\//,
  8    /gems/,
  9    /spec\/spec_helper\.rb/,
 10    /lib\/rspec\/(core|expectations|matchers|mocks)/
 11
 12  This list can be modified or replaced with the `backtrace_clean_patterns` option. Additionally, rspec can be run with the `--backtrace` option to skip backtrace cleaning entirely.

 14  Scenario: default configuration
 15    Given a file named "spec/failing_spec.rb" with:
 16    """ruby
 17    describe "2 + 2" do
 18      it "is 5" do
 19        (2+2).should eq(5)
 20      end
 21    end
