I'm using Rspec and Capybara. How can I write a step to check a checkbox? I've tried check by value but it can't find my checkbox. I'm not sure what to do, as I have in fact same ID with different values Here is the code: <input id="cityID" type="checkbox" style="text-align: center; opacity: 0;" value="61" name="cityID"> <input id="cityID" type="checkbox" style="text-align: center; opacity: 0;" va
