From df4493d553272a948a2683210caa0cb04a2063e3 Mon Sep 17 00:00:00 2001 From: feder-cr <85809106+feder-cr@users.noreply.github.com> Date: Tue, 9 Jun 2026 17:53:11 +0200 Subject: [PATCH] test(e2e): run the real detectors (BotD + FingerprintJS OSS) on CI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of only our hand-rolled signal checks, load the actual MIT detection libraries against the patched binary and assert it isn't flagged: - BotD (the client-side bot detector FingerprintJS Pro itself uses): detect() must return bot=false (no automation/headless tell). - FingerprintJS OSS: visitorId present and stable across two fresh launches with the same seed (drift = per-session entropy = a bot tell). Hermetic: the libs are vendored (tests/vendor/, pinned, MIT) and served from a localhost server — no external CDN (Firefox tracking-protection blocks it anyway), no IP/network dependency, runs identically on a dev box and the GitHub runner.
