// Robustness Tests - Socket Configuration Package
|
|
//
|
|
// This file contains robustness and error recovery tests to verify that the
|
|
// socket/config package handles unusual, malformed, or pathological inputs gracefully.
|
|
//
|
|
// Test Coverage:
|
|
// - Edge case addresses: Very long hostnames, unusual characters, malformed input
|
|
// - Special characters: Unicode, null bytes, control characters in addresses
|
|
// - Empty and whitespace: Empty strings, whitespace-only values, padding
|
|
// - Extreme values: Very large ports (>65535), negative values, overflow conditions
|
|
// - Invalid TLS configurations: Missing certificates, incomplete configurations
|
|
// - Unix socket specifics: Non-existent paths, permission conflicts, path length limits
|
|
// - Platform-specific behavior: Cross-platform validation consistency
|
|
// - Error message clarity: Meaningful errors for common mistakes
|
|
// - Recovery: Ability to fix and revalidate after errors
|
|
//
|
|
// Robustness Philosophy:
|
|
// The package should never panic or produce undefined behavior. All invalid
|
|
// inputs should result in clear error messages that help users diagnose and
|
|
// fix configuration problems. The tests verify that the package degrades
|
|
// gracefully and provides actionable feedback.
