如何在Rails / Capybara中测试页面重新加载？

Question

I am using Capybara for acceptance testing and I have several scenarios, where I need to test if a page has reloaded or not:

1) If I leave a search input field empty and click on the search icon I want to verify that nothing happens and in particular that the page does not reload.

2) On the results page I have three sorting options for results. When I click on a sorting button the page reloads with the chosen sorting criterion applied. I have some trouble with clicking an element using Capybara or even pure JavaScript, so a means for me to check if the element is clicked at all is to check if the page has been reloaded. So how do I do that?
