Services config testing: serveconf_test.go 0→581 lines, 10 tests!
Comprehensive test suite for ipn/conffile/serveconf.go (239 lines): ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📦 serveconf_test.go: 0→581 lines (10 tests) Target: serveconf.go (239 lines, Tailscale Services config) Coverage: 1️⃣ Target.UnmarshalJSON (1 test, 12 cases) • TUN mode: "TUN" → ProtoTUN • HTTP/HTTPS/HTTPS+insecure protocols • TCP, TLS-terminated-TCP protocols • File protocol with path cleaning • IPv6 addresses: [::1]:8080, [2001:db8::1]:443 • Error cases: no protocol, unsupported protocol 2️⃣ Target.MarshalText (1 test, 7 cases) • All protocols: TUN, http, https, tcp, file • Format: "protocol://destination:port" • TUN special case: "TUN" • Unsupported protocol → error 3️⃣ Round-trip Testing (1 test, 7 cases) • Unmarshal → Marshal → Unmarshal • Verify Protocol, Destination, DestinationPorts • All protocol types 4️⃣ Protocol Constants (1 test, 7 protocols) • ProtoHTTP = "http" • ProtoHTTPS = "https" • ProtoHTTPSInsecure = "https+insecure" • ProtoTCP = "tcp" • ProtoTLSTerminatedTCP = "tls-terminated-tcp" • ProtoFile = "file" • ProtoTUN = "TUN" 5️⃣ Port Ranges (1 test, 2 cases) • Single port: 8080 • Port range: 8000-8100 6️⃣ findOverlappingRange (1 test, 7 cases) • No overlap, exact match • Needle contains haystack, vice versa • Partial overlaps (start/end) • Empty haystack 7️⃣ ServicesConfigFile Structure (1 test) • Version = "0.0.1" • Services map validation • Endpoints configuration 8️⃣ ServiceDetailsFile.Advertised (1 test, 3 cases) • opt.Bool: true, false, unset • Get() returns proper values 9️⃣ File Path Cleaning (1 test, 4 cases) • Absolute: /var/www/html • Relative: ./public → public • Double slashes: var//www → var/www • Parent refs: var/www/../static → var/static 🔟 IPv6 Addresses (1 test, 2 cases) • [::1]:8080 • [2001:db8::1]:443 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Test Highlights: ✅ JSON marshaling/unmarshaling ✅ All 7 service protocols ✅ Port range overlap detection ✅ Path cleaning & normalization ✅ IPv6 support ✅ Error handling for invalid inputs STATS: Before: 239-line file with NO dedicated tests After: 581 lines of tests, 10 test functions Coverage boost: Service config parsing fully tested!pull/17963/head
