javascript: Undefined javascript function in Selenium test with Capybara

vendredi 2 janvier 2015

I have a page with a Javascript function in HTML on the page:


 <body>
    ...


<script type="text/javascript">

    function myfunc(){
        // do smth
    }
</script>

 </body>

I'm using Capybara with Selenium Webdriver in my RSpec tests.

After visiting this page I want to call this function:


it "my test" do
  visit "http://ift.tt/1xePZkp"

  page.execute_script "myfunc(); "

end

Almost all time this test is OK. But sometimes I get an error:


Selenium::WebDriver::Error::JavascriptError: myfunc is not defined

How to fix this problem? Is it because Selenium is calling the function before the whole HTML page (with Javascript on it) is loaded ?
