Is it possible to test existance of js function in page using Capybara? if so, can I make a call and check result?
Capybara is used to test the overall functionality of your web application by actually rendering the page. When you are using an engine that can execute Javascript (the default Rack::Test engine does not), you can use it to check that your page is indeed rendered correctly after executing the relevant Javascript. There are ways to test a function’s existence by calling
page.execute_script("typeof yourFunctionName == 'function'")(and only select engines support this) and check its value but know that Capybara it is not designed to be a Javascript test framework. You should use Jasmine for that.
