Summary
tests/unit/browsers/test_stagehand_browser_controller.py::test_fingerprint_headers_set_on_new_pageoccasionally fails on Windows runners withplaywright._impl._errors.Error: StagehandPage.goto: net::ERR_NO_BUFFER_SPACE(see this run). This is the known Windows-only resource flake that already affects parallel Playwright tests under xdist load — the runner exhausts socket buffer space.Following the same mitigation pattern already used in
test_adaptive_playwright_crawler.py:240, the test is now marked@pytest.mark.flaky(rerun=3, ...)so transientERR_NO_BUFFER_SPACEfailures are retried instead of breaking CI.
