Add have_selector() matcher to RSpec Request Specs
If you are used to writing controller specs, you are probably comfortable with the `have_selector matcher. However, in request specs this matcher is not available. By default, you can only do text search inside the request body which leads to brittle assertions.
You can add the
have_selector matcher by updating your RSpec config to include the Capybara matchers on request specs as well.
RSpec.configure do |config|
config.include Capybara::RSpecMatchers, type: :request
Then you can write more confident Request specs by using assertions like
expect(response.body).to have_selector('ul li', text: 'List content here!')
