// TableTestStandards defines standardized field names and patterns for table-driven tests
// This file serves as documentation and helper types for consistent table test structure
//
// IMPLEMENTED STANDARDIZATION:
// Successfully standardized field naming across all cmd test files:
// - expectedOut/expectedOutput → wantOutput
// - expectError → wantError
// - expectedError → wantErrorMsg
//
// Files standardized:
// - cmd_commands_test.go (multiple test functions)
// - cmd_root_test.go (completion and execute tests)
// - cmd_logswatch_test.go (logs watch tests)
// - cmd_service_test.go (service command tests)
// - status_command_refactored_test.go (status tests)
