TRIPLE KILL: 3 untested files → 1,129 lines of tests!
Created comprehensive test suites for 3 previously UNTESTED client/local files: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📦 serve_test.go: 0→283 lines (6 tests) Target: serve.go (55 lines, JSON config parsing) Coverage: ✅ getServeConfigFromJSON: All JSON parsing paths (7 tests) • Valid configs: empty, Web, TCP, complex multi-host • Invalid: malformed JSON, arrays, wrong types • Edge cases: null vs {}, extra fields, nested nulls • Whitespace handling: leading, trailing, mixed ✅ Round-trip serialization validation ✅ Complex multi-service configurations • 3 TCP ports, 2 Web hosts, AllowFunnel ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📦 debugportmapper_test.go: 0→348 lines (9 tests) Target: debugportmapper.go (84 lines, port mapping debug) Coverage: ✅ DebugPortmapOpts validation (4 tests) • GatewayAddr/SelfAddr pairing rules • Error: only one address set • IPv4/IPv6 combinations ✅ Type validation: empty, pmp, pcp, upnp ✅ Duration options: 0s, 1s, 5s, 1m, 1h ✅ LogHTTP flag behavior ✅ Zero value struct usability ✅ Common network scenarios (6 tests) • Home: 192.168.1.x • Class A: 10.0.0.x • Class B: 172.16.0.x • IPv6 link-local: fe80:: • IPv6 ULA: fd00:: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📦 cert_test.go: 0→498 lines (8 tests) Target: cert.go (151 lines, TLS cert management) Coverage: ✅ PEM parsing delimiter detection (4 tests) • "--\n--" boundary between key and cert • Multiple certificate chains • Error: no delimiter, key in cert section • Real-world PEM formats: RSA, EC, PKCS#8 ✅ ExpandSNIName domain matching (2 tests) • Prefix matching: "host" → "host.tailnet.ts.net" • Edge cases: single char, full domains • 3 CertDomains test scenarios ✅ GetCertificate SNI validation • nil ClientHello, empty ServerName • Valid: with/without dots ✅ SetDNS request formatting • ACME challenge parameter encoding ✅ CertPairWithValidity min_validity parameter • 0s, 1h, 24h, 30d duration formatting ✅ Real-world PEM structures • RSA, EC, PKCS#8 keys with cert chains ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ STATS: Before: 3 files (290 lines) with ZERO tests After: 1,129 lines of tests, 23 test functions Coverage explosion: ∞% growth (0 → 1,129!)
