[vkuprin]

Summary

End-to-end security testing framework using Playwright to validate context isolation and sandbox configurations, helping prevent certain classes of vulnerabilities in the Wire desktop application.

Changes

Test Coverage

• Context Isolation: Validates that renderer processes cannot access Node.js APIs
• Sandbox Validation: Ensures proper sandbox configuration
• Exposure Detection: Tests for potential attack vectors
• Regression Testing: Verifies core app functionality remains intact

Testing

The test suite can be run with:

cd test/e2e-security

Notes

• Tests are designed to run in CI/CD pipeline for continuous security validation
• Framework is extensible for additional security test scenarios
• Test artifacts (reports, screenshots) are excluded from version control
