End-to-end antibot-detection tests that verify a pip-installed camoufox release works correctly — both the Firefox binary and the Python package — using real proxies for each browser context.

• Python 3.9+
• Node.js (for building the TypeScript checks bundle via esbuild)
• At least one proxy in proxies.txt

# 1. Add your proxies (see format below)
# 2. Run the test script — it handles everything else automatically
./run_tests.sh

run_tests.sh will:

1. Install npm deps in ../build-tester/ (for esbuild, first run only)
2. Create a .venv virtualenv (first run only)
3. Install camoufox from the local ../pythonlib source
4. Download the camoufox browser binary
5. Run the full test suite

Tests require real proxies. Each context gets its own proxy, and the WebRTC IP is automatically derived from the proxy server address.

Create proxies.txt in this directory with one proxy per line:

user:pass@domain:port

Example:

alice:[email protected]:10000
bob:[email protected]:10000
alice:[email protected]:10001

• Blank lines and lines starting with # are ignored
• Proxies are assigned round-robin across the 6 test profiles
• Fewer proxies than profiles is fine — they cycle

If you prefer to run steps individually:

# Install build-tester deps (once)
cd ../build-tester && npm install && cd ../service_tests

# Create and activate virtualenv
python3 -m venv .venv
source .venv/bin/activate

# Install camoufox from local source
pip install -e ../pythonlib

# Download the browser binary
python -m camoufox fetch

# Run tests
python run_tests.py

./run_tests.sh [options]
python run_tests.py [options]

  --browser-version VER   Camoufox version specifier (default: official/stable)
                          e.g. official/prerelease/146.0.1-beta.50
  --profile-count N       Number of profiles to test (1-6, default: 6)
  --proxies PATH          Path to proxies file (default: proxies.txt)
  --headful               Run with visible browser window
  --no-cert               Skip certificate generation
  --save-cert PATH        Save certificate text to a file
  --secret KEY            HMAC signing key for the certificate

6 browser contexts run simultaneously — 3 macOS profiles and 3 Linux profiles — each with:

• A unique fingerprint generated by camoufox via BrowserForge (navigator, screen, WebGL, fonts, voices, audio/canvas seeds)
• A distinct timezone
• Its own proxy, with WebRTC ICE candidates spoofed to the proxy's IP

Each context is scored across these categories:

A grade of A or B exits with code 0. Anything worse exits with code 1.

The cross-profile uniqueness section confirms each context has distinct audio, canvas, timezone, and screen fingerprints — verifying camoufox generates genuinely different identities per context.

If a check fails, fix it in the Python package (../pythonlib/camoufox/), not in the test. The test is intentionally a black-box validator — it only uses the public AsyncNewContext API and trusts camoufox to produce correct fingerprints.
