specify_line_number.feature

Feature: run specific examples by line number

In order to run a single example from command line
RSpec allows you to specify the line number of the example(s) to run

Scenario: --line syntax on single example
  Given a file named "example_spec.rb" with:
    """
    describe "an example" do
      it "has not yet been implemented"
      it "has been implemented" do
        true
      end
    end
    """
  When I run "spec example_spec.rb --line 2"
  Then the stdout should match "1 example, 0 failures, 1 pending"
  And the stdout should match "example_spec.rb:2"

Scenario: colon line syntax on single example
  Given a file named "example_spec.rb" with:
    """
    describe "an example" do
      it "has not yet been implemented"
      it "has been implemented" do
        true
      end
    end
    """
  When I run "spec example_spec.rb:2"
  Then the stdout should match "1 example, 0 failures, 1 pending"
  And the stdout should match "example_spec.rb:2"
