Scenario: link_to accepts a :query option that appends a query string
Given a fixture app "indexable-app"
And a file named "source/link_to.html.erb" with:
"""
<%= link_to "Needs Index String", "/needs_index.html", :query => "foo" %>
<%= link_to "Needs Index Hash", "/needs_index.html", :query => { :foo => :bar } %>
"""
And the Server is running at "indexable-app"
When I go to "/link_to/"
Then I should see '<a href="/needs_index/?foo">Needs Index String</a>'
Then I should see '<a href="/needs_index/?foo=bar">Needs Index Hash</a>'
