从下拉列表中选择时找不到选项元素

Question

即使提供了正确的 xpath 也无法单击下拉菜单。请在下面找到代码供您参考。这里我使用 Select class.

底页：

def SelectSumInsured(self,sumvalue):
    sumdropdown = Select(self.driver.find_element(By.XPATH, "//select[@formcontrolname = 'income']"))
    suminsured = sumdropdown.select_by_value(sumvalue)
    return suminsured

页面对象屏幕：

class HealthInsurancePage(BasePage):

    def __init__(self, driver):
        super().__init__(driver)


    def SelectSum(self,sumvalue):
        self.SelectSumInsured(sumvalue)

测试脚本：

现在在测试脚本中，我使用了 pytest 参数化数据驱动方法，它应该 select 根据我在 excel sheet 中提供的数据下拉值。

class Test_RSA_Health(BaseTest):
@pytest.mark.parametrize("pin,sumvalue", dataProvider.get_data("excelsheetname"))
def test_RSA_Health(self,pin,sumvalue):
    home = HomePage(self.driver)
    healthinsuranepage = home.SelectHealth()
    self.VerifyPresence_PinCodeTextBox()
    healthinsuranepage.landing_page()
    healthinsuranepage.InputPin(pin)
    healthinsuranepage.SelectSum(str(sumvalue))

错误：在执行过程中，我看到下拉菜单甚至没有被点击，我收到以下错误供您参考

selenium.common.exceptions.NoSuchElementException: Message: Cannot locate option with value: 700000

但是如果我使用相同的 xpath 使用简单的点击方法，则下拉菜单点击成功。

self.driver.find_element(By.XPATH, "//select[@formcontrolname = 'income']").click

我的问题是为什么下拉菜单没有使用 Select class?

单击

应要求，以下内容供您参考

<select _ngcontent-tpo-c7="" formcontrolname="income" class="ng-pristine ng-valid ng-touched">
<!---->
<option _ngcontent-tpo-c7="" class="ng-star-inserted">100000</option>
<option _ngcontent-tpo-c7="" class="ng-star-inserted">200000</option>

<option _ngcontent-tpo-c7="" class="ng-star-inserted">4000000</option>
<option _ngcontent-tpo-c7="" class="ng-star-inserted">5000000</option>

<option _ngcontent-tpo-c7="" class="ng-star-inserted">10000000</option>
</select>

我写的xpath是

//select[@formcontrolname = 'income'] `or` `//select[@class='ng-pristine ng-valid ng-touched']`

Answer 1

这个错误信息...

raise NoSuchElementException("Cannot locate option with value: %s" % value)
selenium.common.exceptions.NoSuchElementException: Message: Cannot locate option with value: 700000

和这个错误信息...

raise NoSuchElementException("Cannot locate option with value: %s" % value)
selenium.common.exceptions.NoSuchElementException: Message: Cannot locate option with value: 500000

...表示 html-select 元素没有具有 value 属性的后代 <option> 元素700000 或 500000.

如果 <select> 具有以下结构，您需要交叉检查：

<select formcontrolname="income" ...>
    <option value="700000" ...>foo</option>
    <option value="500000" ...>bar</option>
</select>

结论

正如您提到的 看到下拉菜单甚至没有被点击，这意味着没有识别出所需的 select元素唯一。

从下拉列表中选择时找不到选项元素

Option element not found while selecting from the dropdown

python

selenium

xpath

html-select

drop-down-menu
