よくある思い込み
MergeConfigMap treats its argument as immutable input and copies it, so changing or reusing the caller's map after the call cannot alter Viper's configuration.
このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。
コントラクト
- assert MergeConfigMap lowercases both top-level and nested keys in the caller-supplied maps themselves
- assert mutating the first caller-owned nested map after MergeConfigMap changes the value returned by GetString, proving that nested map was retained rather than copied
- assert a later MergeConfigMap deep-merges its replacement and new sibling into the first caller-owned nested map while also normalizing the later input in place
- assert a merge after Set changes the aliased config map underneath but GetString still returns the explicit Set value because the config rung remains lower priority
