#15697

💥 What does this PR do?

It just adds type hints for WebElement.find_element(s) value argument

🔧 Implementation Notes

Because WebDriver.find_element(s) is typed the same way, and adding type hints here makes type checkers happy

💡 Additional Considerations

• Yes, probably docs

🔄 Types of changes

• Cleanup (formatting, renaming)

Description

• Add type hints for value parameter in find_element and find_elements

• Specify value argument as str | None for consistency with WebDriver

• Improve type checker compatibility for WebElement locator methods

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Add validation for None value In the find_element method, add a check to raise a ValueError if the value parameter is None to prevent unexpected behavior and improve error handling. py/selenium/webdriver/remote/webelement.py [510-533] def find_element(self, by=By.ID, value: str | None = None) -> WebElement: """Find an element given a By strategy and locator. Args: by: The locating strategy to use. Default is `By.ID`. Supported values include: `By.ID`, `By.XPATH`, `By.LINK_TEXT`, `By.PARTIAL_LINK_TEXT`, `By.NAME`, `By.TAG_NAME`, `By.CLASS_NAME`, `By.CSS_SELECTOR` value: The value to use for the locator. Returns: The `WebElement` object that was found. Raises: NoSuchElementException: if the element wasn't found. """ + if value is None: + raise ValueError("Locator value cannot be None") by, value = self._parent.locator_converter.convert(by, value) return self._execute(Command.FIND_CHILD_ELEMENT, {"using": by, "value": value})["value"] Apply / Chat Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies that passing value=None to find_element is a valid but likely unintended use case that can lead to subtle bugs. Adding an explicit check improves the robustness and clarity of the API, which is a valuable improvement.	Medium
