如何验证文本字段中的值是否与我输入的值相同？

Question

我对Python和Selenium非常陌生，我想我需要使用Assert命令来验证文本字段是否有我通过Selenium输入的内容。你知道吗

我找了一个小时都找不到答案。你知道吗

这是我的密码：

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains as AC
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import Select, WebDriverWait

driver = webdriver.Ie()

driver.get("https://bie.farmersinsurance.com/")

WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "/html/body/div/form/table/tbody/tr[5]/td/table/tbody/tr/td/table/tbody/tr[2]/td/table/tbody/tr[1]/td[1]/input"))).send_keys("tess893")

element = driver.find_element_by_xpath("/html/body/div/form/table/tbody/tr[5]/td/table/tbody/tr/td/table/tbody/tr[2]/td/table/tbody/tr[1]/td[1]/input")
assert element.text == "tess893"

以下是我的结果：

AssertionError

我不知道为什么我会得到一个AssertionError。根据我所读的，它不应该抛出任何错误。你知道吗

Answer 1

.text不是您要查找的属性。 It returns the visible text between the elements tags

您需要输入元素的value。 我想你应该用element.get_attribute('value')

下面的assert语句应该有效

assert element.get_attribute('value') == "tess893"

Answer 2

您的代码语法正确，但assert就是这样工作的。你知道吗

如果条件为真，assert (condition)将不起任何作用，但是如果条件为假，它将给出一个错误。你知道吗

“assert”断言element.text == "tess893"，如果它给出AssertError，那么元素.text不等于“tess893”。可能是xpath错误，或者它包含了不同的文本，但不确定。你知道吗
