python - 元素引发 TimeoutException

Question

我在 selenium 中进行测试有问题，我尝试使用其他等待方法，但没有任何效果。

html

<span class="MuiTypography-root MuiListItemText-primary MuiTypography-body1">Sign Out</span>

log_out.py

imports


    @when('I click on sign out button')
    def step_impl(context):
        wait = WebDriverWait(context.browser, 20)
        #navbar_right_content = context.browser.find_element_by_css_selector("div[class^='navbar-user-profile-menu']")
        navbar_right_content = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR,"div[class^='menu']")))
        navbar_right_content.click()
        sign_out = wait.until(EC.visibility_of_element_located((By.XPATH,'//span*[contains(text(), "Sign Out")]')))
        sign_out.click()

错误
