Why Isn't My Selenium WebDriverWait Working as Expected When Handling New Windows?

WebDriverWait Not Responding as Expected

Selenium's WebDriverWait is intended to wait for specific conditions to be met before proceeding with actions. However, in some cases, it may not function as expected, as described in the given scenario.

The issue lies in the choice of expectation when waiting for elements on a newly opened window. The original code uses the presence_of_element_located() method, which checks if an element is present on the DOM but does not ensure its visibility or interactivity. This can lead to errors if the element is not yet fully loaded or is hidden from view.

To address this, the appropriate expectation to use is element_to_be_clickable(), which ensures that an element is both visible and clickable before continuing. This is important for newly opened windows that may take some time to fully initialize.

Implementation:

Replace the original WebDriverWait statement with the following:

try:
    myElem = WebDriverWait(self.browser, delay).until(EC.element_to_be_clickable((By.XPATH, xpath)))

By using element_to_be_clickable(), WebDriverWait will wait until the element in the new window is not only visible but also interactable. This should resolve the intermittent failures in selecting elements in the newly opened window.

Understanding Expectation Methods:

For reference, here are the definitions of the relevant expectation methods in Selenium:

• presence_of_element_located(locator): Checks if an element is present on the DOM, but does not ensure visibility or interactivity.
• visibility_of_element_located(locator): Checks if an element is present on the DOM and is visible (has a height and width greater than 0).
• element_to_be_clickable(locator): Checks if an element is visible, enabled, and interactable (clickable).
