用于alert_is_present()和switch_to_alert()的函数

Question

我有代码(python / selenium)：

    # Alert start
    WebDriverWait(self.driver, 5).until(EC.alert_is_present())
    self.driver.switch_to_alert().dismiss()
    # Alert end

第一行在浏览器中等待警报，第二行按下“取消”按钮关闭此窗口。它工作得很好。我决定创建两个函数。

    def alertIsPresent(self, timeout=10):
        WebDriverWait(self.driver, timeout).until(EC.alert_is_present())

    def alertDismiss(self):
        alert = self.driver.switch_to_alert()
        alert.dismiss()

我把这个函数叫做：

    PageObject.alertIsPresent()
    PageObject.alertDismiss()

最后一个")“加了下划线，因为”参数自填“...我是python的新手，你能给我一些建议吗？

pageObjectClass：

class PageObject:

def __init__(self, driver, xpathLocator):
    self.driver = driver
    self.locator = xpathLocator
    self.wait = WebDriverWait(self.driver, 100)

def waitElementToBePresent(self, timeout=10):
    WebDriverWait(self.driver, timeout).until(
        EC.visibility_of_element_located((By.XPATH, self.locator)))

def elementIsPresent(self):
    return EC.visibility_of_element_located((By.XPATH, self.locator))

def alertIsPresent(self, timeout=10):
    WebDriverWait(self.driver, timeout).until(EC.alert_is_present())

def alertDismiss(self):
    alert = self.driver.switch_to_alert()
    alert.dismiss()

Answer 1

您还没有提到Selenium的python客户端的版本信息。

但是，根据当前的实现和documentation

switch_to

SwitchTo: an object containing all options to switch focus into

Usage: driver.switch_to.alert

因此，您需要有效地替换以下代码行：

alert = self.driver.switch_to_alert()

通过以下方式：

alert = self.driver.switch_to.alert

Answer 2

不需要使用两个函数，EC.alert_is_present()将返回警报

def alertIsPresent(self, timeout=10):
    return WebDriverWait(self.driver, timeout).until(EC.alert_is_present())

您还需要从类实例调用它，而不是从类型

PageObject(driver).alertIsPresent().dismiss()
