在用python编写自动化脚本时，页面加载时间太长，无法找到元素。如何解决这个问题？

Question

@with_setup(setup_module,teardown_module)

def test_checklist():

    uname = Util.findElement("username")

    if uname.is_displayed():
        uname.send_keys("crussell")

    pwd = Util.findElement("password")

    if pwd.is_displayed():
        pwd.send_keys("welcome")

    loginelem = Util.findElement("login_btn")

    if loginelem.is_displayed():
        loginelem.click()

    wbelmnts = Util.findElements("Left_Menu")

    Util.clickElementFromList(wbelmnts, "Job Postings")

NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@class='loginForm']//div[@class='formGroup']/input[@name='login']"}

Answer 1

puttime.sleep(5)它将等待页面加载。你知道吗
