How to Handle Dynamic Waits in Selenium: Ensuring Elements Load Properly

digital.6 · February 10, 2025, 10:46am

Hi Everyone,

I’m using Selenium WebDriver to automate a login process, but the page takes time to load after clicking the login button. How can I ensure my script waits for the elements to be visible before interacting with them? Any suggestions?

Thanks.
Gautam

You can find example from here. After login, I am waiting for suitable indicator element. I have small utility methods in my bade class:

TatuLund/uiunittest-demo/blob/v24/src/test/java/com/example/application/integrationtest/AbstractViewTest.java#L71


      
              executeScript(
                      "!!document.activeElement ? document.activeElement.blur() : 0");
          }
          
          public void login(String user, String pass) {
              var loginForm = $(LoginFormElement.class).first();
              loginForm.getUsernameField().setValue(user);
              loginForm.getPasswordField().setValue(pass);
              blur();
              loginForm.getSubmitButton().click();
              waitForElementPresent(By.id("app-layout"));
          }
          
          public void wait(int millis) {
              try {
                  Thread.sleep(millis);
              } catch (InterruptedException e) {
              }
          }

Just to clarify: waitForElementPresent is a Vaadin Testbench helper that under the hood uses Selenium wait feature.

new WebDriverWait(getDriver(), Duration.ofSeconds(timeoutInSeconds)).until(condition)
