def add_matcher(matcher_name)
  positive_name = CapybaraMiniTestSpec::PositiveTestName.new(matcher_name)
  negative_name = CapybaraMiniTestSpec::NegativeTestName.new(matcher_name)
  [positive_name, negative_name].each do |test_name|
    CapybaraMiniTestSpec.define_expectation(test_name)
  end
end

.define_assertion(test_name) ⇒ Object

Define an assertion using test_name. For example, if the test name is have_css, the assertion would be called assert_page_has_css.

Use either of Capybara::RSpecMatchers. Assert that it matches, and pass its failure message if it doesn’t.
