rspec users - May 2012 - how can I do an "or" within the context of a matcher?

Capybara has two methods:

page.has_button?

and

page.has_link?

...  I am wondering, how can I make a helper method that will be
satisfied by one or the other?  In other words, I want to be able to do:

page.should have_link_or_button("blah")

def have_link_or_button(locator)
  have_link(locator) || have_button(locator)
end

But that doesn''t work...  Is there any way to do this?

You need a custom matcher, something like this:

RSpec::Matchers.define :have_link_or_button do |locator|
  match do |page|
    page.has_button?(locator) || page.has_link?(locator)
  end
end

BTW, I believe Capybara has a method that checks for a button *or* link - look
into that.
