In Progress 🚧

STEP 3.2: Remaining Core Components

• ⏳ internal/certauth/certauth_test.go - Certificate authority tests
• ⏳ internal/writer/writer_test.go - WARC writer tests
• ⏳ internal/writer/gowarc_conformity_test.go - gowarc API conformity

Pending 📋

STEP 3.3: Complex Components

• internal/proxy/recorder_test.go - Digest calculation tests
• internal/proxy/proxy_test.go - Server lifecycle tests
• internal/proxy/handler_test.go - HTTP handling tests
• internal/proxy/mitm_test.go - HTTPS MITM tests

STEP 3.4: Coverage Verification

• Target: 70% overall coverage
• Target: 75%+ for critical packages (proxy, writer, pipeline)

STEP 4: Comparison Tools

• test/functional/lib/warc_compare.go - WARC file comparator
• test/functional/lib/sqlite_compare.go - SQLite DB comparator
• test/functional/lib/common.sh - Shared bash utilities

STEP 5: Functional Tests (10 scenarios)

• 01_http_basic.sh - Basic HTTP GET
• 02_https_mitm.sh - HTTPS MITM
• 03_post_body.sh - POST with body
• 04_headers.sh - Custom headers
• 05_compression_gzip.sh - GZIP compression
• 06_digest_sha1.sh - SHA1 digest
• 07_digest_sha256.sh - SHA256 digest
• 08_digest_blake3.sh - BLAKE3 digest
• 09_file_rotation.sh - WARC rotation
• 10_concurrent.sh - Concurrent requests

STEP 6: Documentation

• Update README.md with testing instructions
• Create Makefile with make test and make test-functional targets

STEP 7: Final Validation

• All unit tests passing
• All functional tests passing
• 70% coverage achieved
• Payload digests match between Python and Go

Next Steps

Priority: Continue STEP 3.2

1. Write internal/certauth/certauth_test.go:

   • Test CA initialization (create new, load existing)
   • Test certificate generation for various hostnames
   • Test wildcard certificate support
   • Test certificate caching
   • Test concurrent cert generation

2. Write internal/writer/writer_test.go:

   • Test WARC writer initialization
   • Test request record creation
   • Test response record creation
   • Test record batch creation
   • Test compression support
   • Test file rotation

3. Write internal/writer/gowarc_conformity_test.go:

   • Validate WARC record format
   • Verify header fields
   • Check digest calculation
   • Validate compression

Then proceed to STEP 3.3 (proxy package tests).

Success Criteria (Before Phase 5)

• ✅ FEATURE_PARITY.md created and comprehensive
• ✅ Test infrastructure directories created
• 🚧 All unit test files written for Phases 1-4 packages (3/6 complete)
• ⏳ Go test coverage ≥70% overall
• ⏳ Critical packages (proxy, writer, pipeline) ≥75% coverage
• ⏳ Comparison tools (warc_compare, sqlite_compare) built
• ⏳ All functional test scenarios 01-10 written
• ⏳ All functional tests pass (Python and Go outputs match)
• ⏳ Payload digests match exactly in all functional tests
• ⏳ README.md updated with testing instructions
• ⏳ All testing work committed to git

Estimated Remaining Work

• STEP 3.2 remaining: 4-6 hours (certauth, writer tests)
• STEP 3.3: 6-8 hours (proxy package tests - most complex)
• STEP 3.4: 1 hour (coverage verification and fixes)
• STEP 4: 8-10 hours (comparison tools are complex)
• STEP 5: 10-12 hours (10 functional test scenarios)
• STEP 6: 2 hours (documentation)
• STEP 7: 2 hours (validation and fixes)

Total: 33-41 hours remaining

Notes

• User is AFK, continue working autonomously
• Focus on unit tests first (as agreed: unit tests → functional tests)
• Table-driven tests preferred (Uber Go style)
• Mock external dependencies
• Test public interfaces
• Each package tests should be committed separately
