Most test suites contain foundational structure requiring additional work.

-### Certificate Fixtures -**Location**: `test/fixtures/` -- Valid TLS 1.3 certificates (multiple validity periods) -- Expired certificates (for error testing) -- Self-signed certificates (for rejection testing) -- Certificate chains (root, intermediate, leaf) -- Client certificates (for mutual TLS testing) - -### Test Key Material -- RSA keys (various sizes) -- ECDSA keys (P-256, P-384) -- Invalid/corrupted keys (for error testing) -- **SECURITY**: All test keys MUST be clearly marked as test-only - -## Quality Assurance - -### Test Coverage Requirements -- **100% WIT Interface Coverage**: Every function, resource, and record must be tested -- **Error Path Coverage**: All error-code variants must have corresponding test cases -- **Security Edge Cases**: All security constraints must have negative tests -- **Platform Coverage**: Tests must pass on Linux, macOS, and Windows WASI runtimes - -### Performance Baselines -- Handshake completion time benchmarks -- Stream throughput measurements -- Memory usage validation -- WASM component size limits - -## Contributing Test Cases - -### Adding New Test Cases -1. Identify the WIT interface element being tested -2. Reference the exact line numbers in `wit/types.wit` -3. Create both positive and negative test cases -4. Validate test works with WASM target -5.
