Lo que suele suponerse
Calling Option.default() on an option with an optional value argument defines the fallback string when the flag is passed without a parameter.
El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.
Contrato
- Passing an option with optional argument without a value sets its parsed option value to boolean true and skips argParser unless Option.preset() is configured.
- assert omitted option with optional argument evaluates to Option.default() with source 'default'
- assert Option.preset() supplies the fallback value and invokes argParser when an optional argument flag is passed bare
- assert explicit CLI argument overrides Option.preset() with source 'cli'
- assert getOptionValueSource() distinguishes between 'cli', 'env', and 'default' sources
- assert Option.conflicts() rejects mutually exclusive flags with CommanderError code commander.conflictingOption
