# First attempting to use Capybara directly, you will ran into issues when trying to set HTTP header. | |
# Using Basic HTTP Authentication requires that we needed to set the header. | |
# Also we need to set the Content-Type and Accept headers to ensure that Rails handles the input and output correctly. | |
# When using Rack, Capybara delegates request and response handling down to Rack::Test. | |
# So I used Rack::Test directly in my step definitions, and it works. | |
# Rack::Test has a module called Rack::Test::Methods that can be mixed into a class to provide it | |
# with methods for get, post, put, delete as well as last_request, last_response, header and more. | |
# I mixed Rack::Test::Methods into the Cucumber world at the top of our API steps file like so: | |
