🔒 No security concerns identified

⚡ Recommended focus areas for review Type Safety The method accesses self.proxyType["string"] without null checking, which could raise KeyError if proxyType is not properly initialized or doesn't contain the "string" key. proxy_type = self.proxyType["string"].lower() result = {"proxyType": proxy_type} Resource Cleanup The fake proxy server cleanup in exception scenarios may not execute properly, potentially leaving servers running and ports occupied. finally: driver.browser.remove_user_context(user_context) fake_proxy_server.shutdown() fake_proxy_server.server_close()

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Validate SOCKS version values Add validation to ensure socksVersion is a valid value (4 or 5) before adding it to the result. Invalid SOCKS versions could cause runtime errors in the BiDi protocol. py/selenium/webdriver/common/proxy.py [346-347] if self.socksVersion is not None: + if self.socksVersion not in [4, 5]: + raise ValueError("socksVersion must be 4 or 5") result["socksVersion"] = self.socksVersion Apply / Chat Suggestion importance[1-10]: 7 __ Why: This suggestion correctly adds validation for socksVersion, improving the robustness of the to_bidi_dict method by preventing invalid values from being sent.	Medium
Learned best practice	Add null checks for dictionary access The code accesses self.proxyType["string"] without checking if self.proxyType exists or if the "string" key is present. Add validation to prevent KeyError exceptions when these properties are None or missing. py/selenium/webdriver/common/proxy.py [329-337] def to_bidi_dict(self): """Convert proxy settings to BiDi format. Returns: ------- dict: Proxy configuration in BiDi format. """ + if not self.proxyType or "string" not in self.proxyType: + raise ValueError("proxyType must be set with a valid string value") proxy_type = self.proxyType["string"].lower() result = {"proxyType": proxy_type} Apply / Chat Suggestion importance[1-10]: 6 __ Why: Relevant best practice - Add null checks and validation for parameters, properties, and return values before using them to prevent NullReferenceException and other runtime errors	Low
General	Use consistent element locator syntax Use the By.TAG_NAME constant instead of the string literal for consistency with other test methods in the same file. This maintains code consistency and follows the established pattern. py/test/selenium/webdriver/common/bidi_browser_tests.py [198] -body_text = driver.find_element("tag name", "body").text +body_text = driver.find_element(By.TAG_NAME, "body").text Apply / Chat Suggestion importance[1-10]: 5 __ Why: The suggestion correctly points out an inconsistent locator strategy and proposes using By.TAG_NAME, which aligns with the rest of the file and improves code quality.
