我有一个像这样的 HTML 元素
<select id="my_id">
<option value="">ALL</option>
<option value="1.0">ALL</option>
<option value="2.0">A</option>
<option value="3.0">B</option>
<option value="4.0">C</option>
</select>
当我在测试文件中使用定义函数时,我想选择并选择一个值 一切正常
my_test_file.py
def _find_and_select(self, elm_id, value):
select_item = Select(self.browser.find_element_by_id(elm_id))
select_item.select_by_value(value)
self._find_and_select("my_id", "1.0")
但是当我转向通用测试文件时
common_file.py
class Common:
@staticmethod
def _find_and_select(browser, elm_id, value):
select_item = Select(browser.find_element_by_id(elm_id))
select_item.select_by_value(value)
my_test_file.py
Common._find_and_select(self.browser, "my_id", "1.0")
会出现错误:
Traceback (most recent call last):
File "D:\iBNet-Prj\ibnet\apps\autotest\contract\tests.py", line 251, in test_search
CommonTest._find_and_select(self.browser, "contractLoanStatus", loanStatus[0])
File "D:\iBNet-Prj\ibnet\apps\common_test.py", line 467, in _find_and_select
select_item = Select(browser.find_element_by_id(elm_id))
File "D:\iBNet-Prj\venv\lib\site-packages\django\forms\widgets.py", line 558, in __init__
super().__init__(attrs)
File "D:\iBNet-Prj\venv\lib\site-packages\django\forms\widgets.py", line 201, in __init__
self.attrs = {} if attrs is None else attrs.copy()
AttributeError: 'WebElement' object has no attribute 'copy'
最佳答案
此错误消息...
File "D:\iBNet-Prj\ibnet\apps\common_test.py", line 467, in _find_and_select
select_item = Select(browser.find_element_by_id(elm_id))
File "D:\iBNet-Prj\venv\lib\site-packages\django\forms\widgets.py", line 558, in __init__
super().__init__(attrs)
File "D:\iBNet-Prj\venv\lib\site-packages\django\forms\widgets.py", line 201, in __init__
self.attrs = {} if attrs is None else attrs.copy()
AttributeError: 'WebElement' object has no attribute 'copy'
...暗示代码行 select_item = Select(browser.find_element_by_id(elm_id))
失败,并且您正在使用 django调用框架 super().__init__(attrs)
并产生错误:
AttributeError: 'WebElement' object has no attribute 'copy'
解决方案
要理想地选择所需的元素,您必须为 element_to_be_clickable()
引发WebDriverWait,并且您可以使用以下任一 Locator Strategies :
使用
CSS_SELECTOR
:select_item = Select(WebDriverWait(browser, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "select#my_id")))) select_item.select_by_value(value)
使用
XPATH
:select_item = Select(WebDriverWait(browser, 10).until(EC.element_to_be_clickable((By.XPATH, "//select[@id='my_id']")))) select_item.select_by_value(value)
注意:您必须添加以下导入:
from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC
