Case insensitive Rspec match

Question

I\'m writing a Capybara test and using Rspec for the assertions. My test is failing because there is a CSS style being applied that is causing the text to be in all caps. How ca

Answer 1

Rspec syntax has changed significantly in 4 years, but this underlying problem still seems like a problem. My solution was to build a custom matcher has_content_i, which was like has_content but is case insensitive. The resulting call looks like:

expect(page).to have_content_i("All Caps")

Here's the source:

RSpec::Matchers.define :have_content_i do |expected|
  match do |actual|
    actual.text =~ /#{Regexp.quote expected}/i
  end

  failure_message do |actual|
     "expected to find text #{expected.inspect} case insensitively in #{actual.text.inspect}"
  end

  failure_message_when_negated do |actual|
    "expected to not to find text #{expected.inspect} case insensitively in #{actual.text.inspect}"
  end
end
