[SOLVED] Selenium WebDriver processes the old page after click()

Selenium WebDriver processes the old page after click()

I run .click() on the link and a new tab opens, the focus becomes on it

self.find_element(PageLocators.BANNER).click()

find_element is my wrapper over the standard function, I just added an explicit wait before the element appears in the DOM:

def find_element(self, locator, time=10):
    return WebDriverWait(self.driver, time).until(
        EC.presence_of_element_located(locator),
        f"Couldn't find element by locator {locator}",
    )

After .click(), I am on a new page, the tab automatically switches to it, but the driver.current_url remains the same. But if you uncomment the line below, then everything works and current_url is updated.

def block_exist(self):
    try:
        # self.driver.switch_to.window(self.driver.window_handles[1]) <--- current_url is not updated without this line
        self.find_element(PageLocators.BLOCK)
        return True
    except:
        return False

Why do I need to use self.driver.switch_to.window(self.driver.window_handles[1]) if the focus is automatically set to a new tab in the browser?

Solution

Selenium does not change focus to a newly opened window until you tell it to.

Without more info, it's hard to answer the rest of your question. If I were to guess, it's because the locator you are using matches an element on the original page as well so it's finding that one.
