selenium-webdriver Wait Waiting For Ajax Requests to Complete
Example
C#
using OpenQA.Selenium
using OpenQA.Selenium.Chrome;
using System.Threading;
namespace WebDriver Tests
{
class WebDriverWaits
{
static void Main()
{
IWebDriver driver = new ChromeDriver(@"C:\WebDriver");
driver.Navigate().GoToUrl("page with ajax requests");
CheckPageIsLoaded(driver);
// Now the page is fully loaded, you can continue with further tests.
}
private void CheckPageIsLoaded(IWebDriver driver)
{
while (true)
{
bool ajaxIsComplete = (bool)(driver as IJavaScriptExecutor).ExecuteScript("return jQuery.active == 0");
if (ajaxIsComplete)
return;
Thread.Sleep(100);
}
}
}
}
This example is useful for pages where ajax requests are made, here we use the IJavaScriptExecutor to run our own JavaScript code. As it is within a while loop it will continue to run until ajaxIsComplete == true and so the return statement is executed.
We check that all ajax requests are complete by confirming that jQuery.active is equal to 0. This works because each time a new ajax request is made jQuery.active is incremented and each time a request complements it is decremented, from this we can deduce that when jQuery.active == 0 all ajax requests must be complete.
