From 971508cbefdcaafd3f464ccb340e487cb8b9ea0e Mon Sep 17 00:00:00 2001 From: Stefan Meinecke Date: Wed, 18 Mar 2026 01:47:19 +0100 Subject: [PATCH 01/14] feat: use local TrackMe instance for TLS fingerprint tests Replace hardcoded tls.peet.ws URLs with a TRACKME_URL environment variable (defaulting to https://tls.peet.ws for backward compatibility) so CI and local tests can run against a local TrackMe Docker instance. - Add docker/trackme/Dockerfile + config.json: builds TrackMe from GitHub (golang:1.24-alpine, no pcap/QUIC, ports 8443/8080) - Add docker-compose.test.yml: runs local TrackMe - Add scripts/setup-trackme-certs.sh: generates self-signed certs; prints SSL_CERT_FILE hint for no-sudo local testing - Update all test files (20 files) to read TRACKME_URL from env - Update blocking-tests.yml and live-tests.yml: - Generate self-signed TLS certs; combine with system CA bundle - Start TrackMe via docker compose and wait for health - Set TRACKME_URL + SSL_CERT_FILE for the test run Tested locally: 22/22 blocking tests pass against https://localhost:8443 --- tests/conftest.py | 13 ++++++- tests/integration/test_api.py | 7 +++- tests/test_async_ja3.py | 35 +++++++++-------- tests/test_force_http1.py | 7 +++- tests/test_frame_headers.py | 25 ++++++------ tests/test_http2.py | 7 +++- tests/test_http2_fingerprint.py | 7 +++- .../test_http2_fingerprint_tlsfingerprint.py | 13 ++++--- tests/test_integration.py | 7 +++- tests/test_integration_tlsfingerprint.py | 13 ++++--- tests/test_ja3_fingerprints.py | 39 ++++++++++--------- tests/test_ja3_fingerprints_tlsfingerprint.py | 25 ++++++------ tests/test_ja4_fingerprints.py | 35 +++++++++-------- tests/test_ja4_fingerprints_tlsfingerprint.py | 13 ++++--- tests/test_module_api.py | 7 +++- tests/test_tls13.py | 7 +++- tests/test_tlsfingerprint_blocking.py | 5 ++- 17 files changed, 156 insertions(+), 109 deletions(-) diff --git a/tests/conftest.py b/tests/conftest.py index 4504da2..da7010b 100644 --- a/tests/conftest.py +++ b/tests/conftest.py @@ -6,6 +6,9 @@ import sys import os +# TrackMe base URL — override with TRACKME_URL env var to point at a local instance +_TRACKME_URL = os.environ.get("TRACKME_URL", "https://tls.peet.ws") + # Add parent directory to path to import cycletls sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..'))) @@ -37,13 +40,19 @@ def cycletls_client_function(): @pytest.fixture def test_url(): """Base test URL for most tests.""" - return "https://tls.peet.ws/api/clean" + return f"{_TRACKME_URL}/api/clean" @pytest.fixture def ja3_test_url(): """TLS fingerprint test URL (replacement for defunct ja3er.com).""" - return "https://tls.peet.ws/api/clean" + return f"{_TRACKME_URL}/api/clean" + + +@pytest.fixture(scope="session") +def trackme_url(): + """TrackMe base URL.

Default remains https://tls.peet.ws so local devs without the local server still hit production. The renamed fixture (trackme_url -> tlsfp_url) and updated docstrings reflect that the local target is Danny-Dasilva/tlsfingerprint.com (the source of tls.peet.ws), not the third-party TrackMe image. --- tests/conftest.py | 25 +++++++----- tests/integration/test_api.py | 10 +++-- tests/test_async_ja3.py | 36 +++++++++-------- tests/test_force_http1.py | 8 ++-- tests/test_frame_headers.py | 26 ++++++------ tests/test_http2.py | 8 ++-- tests/test_http2_fingerprint.py | 11 ++--- .../test_http2_fingerprint_tlsfingerprint.py | 8 ++-- tests/test_integration.py | 12 +++--- tests/test_integration_tlsfingerprint.py | 12 +++--- tests/test_ja3_fingerprints.py | 40 ++++++++++--------- tests/test_ja3_fingerprints_tlsfingerprint.py | 8 ++-- tests/test_ja4_fingerprints.py | 36 +++++++++-------- tests/test_ja4_fingerprints_tlsfingerprint.py | 8 ++-- tests/test_module_api.py | 10 +++-- tests/test_tls13.py | 11 ++--- tests/test_tlsfingerprint_blocking.py | 8 ++-- 17 files changed, 154 insertions(+), 123 deletions(-) diff --git a/tests/conftest.py b/tests/conftest.py index 4e4a250..3614243 100644 --- a/tests/conftest.py +++ b/tests/conftest.py @@ -2,17 +2,20 @@ pytest configuration and shared fixtures for CycleTLS tests.

Both blocking-tests and live-tests workflows now: 1. Check out Danny-Dasilva/tlsfingerprint.com@master into .tlsfingerprint-server/ 2. Generate a self-signed cert via openssl 3. Patch config.example.json to disable mongo/log_to_db 4. Build + start the container via the upstream docker-compose.yml (NET_ADMIN/NET_RAW caps, ports 80/443/443-udp) 5. Wait up to 90s for /api/clean to respond 6. Inject TLSFP_URL=https://localhost and SSL_CERT_FILE so tests trust the self-signed cert and target the local server 7. Tear the container down at the end of the run Tests still fall back to https://tls.peet.ws when TLSFP_URL is unset, so local developers without Docker keep working against production.

The CycleTLS Go transport caches connections +globally, so a closed connection can leak into the next test as +`use of closed network connection`. Most fixtures default +`enable_connection_reuse=False` to avoid this.

The blocking test module (tests/test_tlsfingerprint_blocking.py) still contained 5 exact-equality JA4_r assertions, including test_ja4r_tls12_fingerprint_exact_match which was the actual CI failure (production tls.peet.ws emits 't12d128h2' for 12 ciphers + 8 extensions unpadded; the local tlsfingerprint.com Docker emits the spec-padded 't12d1208h2'; equality fails). Promote parse_ja4r and assert_ja4r_equivalent helpers from test_ja4_fingerprints.py into tests/conftest.py as public names so they can be reused. Both test files now import from conftest.

Fix: only force `enable_connection_reuse=False` when the URL is the local tlsfingerprint.com server (TLSFP_URL). Public endpoints (httpbin.org) keep the default keep-alive behaviour. --- tests/conftest.py | 17 +++++++++++------ tests/test_force_http1.py | 17 +++++++++++++---- 2 files changed, 24 insertions(+), 10 deletions(-) diff --git a/tests/conftest.py b/tests/conftest.py index 8db5818..e86d249 100644 --- a/tests/conftest.py +++ b/tests/conftest.py @@ -25,16 +25,21 @@ def cycletls_client(): Session-scoped CycleTLS client fixture.
