[BUGS] Current Bugs of Patchright

These are the current Bugs of Patchright, sorted by Type

Note

For Setup Convienience Reasons, Patchright is currently mainly tested on the Playwright Python Pytest Cases. The Failing Test Cases therefore link to these Python Tests. See the Automatic Patchright Chromium Test

Console (32 Failing Tests)

Explanation: Patchright disabled the Console CDP Domain as it causes full detection. There no current plans/ways to circumvent this detection. This Bug affects the following Playwright Features: ConsoleMessage, PageError.

Failing Test Cases

Websocket Routing (6 Failing Tests)

Explanation: Probably not solvable stealthy without a custom MITM-Proxy. See Issue #31.

Failing Test Cases

test_route_web_socket.py::test_should_work_with_ws_close
test_route_web_socket.py::test_should_pattern_match
test_route_web_socket.py::test_should_work_with_server
test_route_web_socket.py::test_should_work_without_server
test_route_web_socket.py::test_should_work_with_base_url
test_route_web_socket.py::test_should_work_with_no_trailing_slash

InitScript Timing (4 Failing Tests)

Explanation: Patchright patches InitScripts by injecting custom script tags into the HTML. This causes some Timing issues, as the Script Tags take longer to load than normal InitScripts.

Failing Test Cases

test_browsercontext.py::test_expose_function_should_be_callable_from_inside_add_init_script
test_page.py::test_expose_function_should_be_callable_from_inside_add_init_script
test_page.py::test_expose_bindinghandle_should_work
test_popup.py::test_should_expose_function_from_browser_context

Disable Popup Blocking (1 Failing Test)

Explanation: Patchright patches Popup crashing by removing the --disable-popup-blocking defaultArg. If you have trouble with this issue and dont worry about Popup Crashing you can re-enable this feature by passing args=["--disable-popup-blocking"]

Failing Test Cases

test_browsercontext.py::test_page_event_should_have_an_opener

Mismatching Request Headers due to Routing (3 Failing Tests)

Explanation: This Bug mainly affects when adding an InitScript. This is a Playwright issue (youll get the same issue when routing normally), affecting returned Request Headers Client-Side. So this doesnt cause any detections. If you need correct Request Headers, youll have to create an issue in the Playwright Repository.

Failing Test Cases

test_network.py::test_request_headers_should_get_the_same_headers_as_the_server
test_network.py::test_request_headers_should_get_the_same_headers_as_the_server_cors
test_network.py::test_should_report_request_headers_array

Unwanted Behaviour

InitScripts on about:blank (Unwanted Behaviour)

Explanation: Because Patchright InitScripts use Routing, they cant affect about:blank, data:text/html,[...] and other Data-URIs. In Patchright Testing, this is solved by just going to an URL with an empty page, for example google.com/blank.html

Failing Test Cases
