Question

我正在 Python 中使用 Selenium 编写自动化测试。不明白为什么下面这段代码中WebdriverWait的until方法需要调用两次，否则文本输入不会被填充。我需要添加或删除什么，以便在不需要两次调用 WebDriverWait.until() 的情况下填充 html 输入字段？该方法如下所示： class SomeClass: usernameId = 'username' passwordId = 'password' def doSomething(self, username, password): wait = WebDriverWait(self.driver, 10) sleep(2) # TODO: find out why one wait is not enough, and how it should be done properly. element = wait.until(EC.element_to_be_clickable((By.ID, self.usernameId))) # Why is the seconde line needed? Without it the input is not filled. It should not be? element = wait.until(EC.element_to_be_clickable((By.ID, self.usernameId))) element.send_keys(username) d = self.driver wait.until(lambda d: element.get_attribute("value") == username)


    pwdElement = wait.until(EC.element_to_be_clickable((By.ID, self.passwordId)))
    # Why is the seconde line needed? Without it the input is not filled. It should not be?
    pwdElement = wait.until(EC.element_to_be_clickable((By.ID, self.passwordId)))
    pwdElement.send_keys(password)
    wait.until(lambda d: pwdElement.get_attribute("value") == password)

    sleep(2)
    inloggenButton = wait.until(EC.element_to_be_clickable((By.ID, self.inloggenButtonId)))
    inloggenButton.click()
    GeneralPage(self.driver).logged_on()

看起来完全多余。
您也可以删除 element = wait.until(EC.element_to_be_clickable((By.ID, self.usernameId))) 行之一和 sleep(2)。
可能是您的网站加载时间过长而 10 秒的超时时间不够。
在这种情况下，您可以将超时设置为 30 甚至 60 秒，如下所示：

class SomeClass:
    usernameId = 'username'
    passwordId = 'password'
    def doSomething(self, username, password):
        wait = WebDriverWait(self.driver, 60)

        # TODO: find out why one wait is not enough, and how it should be done properly.
        element = wait.until(EC.element_to_be_clickable((By.ID, self.usernameId)))

        element.send_keys(username)
        d = self.driver
        wait.until(lambda d: element.get_attribute("value") == username)


        pwdElement = wait.until(EC.element_to_be_clickable((By.ID, self.passwordId)))
        # Why is the seconde line needed? Without it the input is not filled. It should not be?
        pwdElement = wait.until(EC.element_to_be_clickable((By.ID, self.passwordId)))
        pwdElement.send_keys(password)
        wait.until(lambda d: pwdElement.get_attribute("value") == password)
    
        inloggenButton = wait.until(EC.element_to_be_clickable((By.ID, self.inloggenButtonId)))
        inloggenButton.click()
    GeneralPage(self.driver).logged_on()

python 需要调用 WebDriverWait 两次
