使用 Selenium + Python 将测试用户输入从一个输入镜像到另一个输入

Question

我正在尝试在 Selenium 中编写一个测试，以确保输入到一个输入中的文本镜像到另一个输入中。我在下面不断收到此错误。

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"/html/body/div/div[2]/div/div/div/div[2]/div[1]/input[1]"}

这是我目前正在使用的代码：

class inputMirror(unittest.TestCase):
def setUp(self):
    self.driver = webdriver.Chrome()
    self.driver.get("https://foo.bar")

def test_mirror_input(self):
#Ensures text from the first input is mirrored into the second input box
    driver = self.driver
    userInput = "Howdy"
    inputBoxOneXpath = driver.find_element_by_xpath('/html/body/div/div[2]/div/div/div/div[2]/div[1]/input[1]')
    inputBoxTwoXpath = driver.find_element_by_xpath('/html/body/div/div[2]/div/div/div/div[2]/div[1]/input[2]')
    inputBoxOneXpath.clear()
    inputBoxOneXpath.send_keys(userInput)
    driver.implicitly_wait(10)
    assert inputBoxTwoXpath.text == userInput
    driver.close()

HTML 代码：

<input type="text" placeholder="Enter text here..." value="">
<input class="textbox" placeholder="Enter text here..." value="" maxlength="80" required="true">

Answer 1

错误说明了一切NoSuchElementException: Message: no such element，这是因为您构造的xpath 无法识别预期的元素。这是供您参考的代码块：

driver = self.driver
userInput = "Howdy"
inputBoxOneXpath = driver.find_element_by_xpath("//input[@type='text' and @placeholder='Enter text here...']")
inputBoxOneXpath.clear()
inputBoxOneXpath.send_keys(userInput)
driver.implicitly_wait(10)
inputBoxTwoXpath = driver.find_element_by_xpath("//input[@class='textbox' and @placeholder='Enter text here...']")
assert inputBoxTwoXpath.get_attribute("value") in userInput
driver.close()

Answer 2

使用提供的 html，您可以：

userInput = "Howdy"
driver.find_element_by_xpath("//input[@type='text' and @placeholder='Enter text here...']").send_keys(userInput)
driver.find_element_by_xpath("//input[@class='textbox' and @placeholder='Enter text here...']").send_keys(userInput)
