From 179689cef7e03c0378e41e5219406253b3a38c01 Mon Sep 17 00:00:00 2001 From: Stefan Meinecke Date: Wed, 18 Mar 2026 01:47:19 +0100 Subject: [PATCH 1/9] 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 --- .github/workflows/blocking-tests.yml | 23 +++++++++++ .github/workflows/live-tests.yml | 23 +++++++++++ .gitignore | 3 ++ docker-compose.test.yml | 16 ++++++++ docker/trackme/Dockerfile | 17 ++++++++ docker/trackme/config.json | 12 ++++++ scripts/setup-trackme-certs.sh | 39 +++++++++++++++++++ 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 ++- 24 files changed, 289 insertions(+), 109 deletions(-) create mode 100644 docker-compose.test.yml create mode 100644 docker/trackme/Dockerfile create mode 100644 docker/trackme/config.json create mode 100755 scripts/setup-trackme-certs.sh diff --git a/.github/workflows/blocking-tests.yml b/.github/workflows/blocking-tests.yml index f5ad1f2..50e9ca5 100644 --- a/.github/workflows/blocking-tests.yml +++ b/.github/workflows/blocking-tests.yml @@ -40,5 +40,28 @@ jobs: - name: Install dependencies run: uv sync --locked --all-extras --dev + - name: Generate TLS certificates for TrackMe + run: | + mkdir -p docker/trackme/certs + openssl req -x509 -newkey rsa:2048 \ + -keyout docker/trackme/certs/key.pem \ + -out docker/trackme/certs/chain.pem \ + -days 1 -nodes \ + -subj "/CN=localhost" \ + -addext "subjectAltName=IP:127.0.0.1,DNS:localhost" + # Combine system CAs with test CA so Go trusts the self-signed cert + cat /etc/ssl/certs/ca-certificates.crt docker/trackme/certs/chain.pem \ + > /tmp/combined-test-cas.crt + + - name: Build and start TrackMe + run: | + docker compose -f docker-compose.test.yml up -d --build + echo "Waiting for TrackMe to become ready..." + timeout 90 bash -c 'until curl -sf https://localhost:8443/api/clean >/dev/null 2>&1;
