# Startup Validation and Config Defaults Tests These tests ensure that the configuration is validated immediately upon loading and that defaults are correctly handled. ## Tests Summary - **`Startup Validation`**: - Verifies that `loadConfig` throws errors for invalid `maxCommandLength` (must be positive). - Verifies that `loadConfig` throws errors for invalid `commandTimeout` (must be >= 1s). - Ensures `loadConfig` validates the `logging` configuration (e.g., checking for path traversal in `logDirectory`). - **`Default Config - logRetentionMinutes`**: - Confirms that `logRetentionDays` is NOT set by default, allowing `logRetentionMinutes` to be the primary default. - Verifies that user-provided `logRetentionDays` correctly overrides `logRetentionMinutes`. - **`Default Config - Limit Naming`**: - Ensures `maxTotalStorageSize` (in-memory) and `maxTotalLogSize` (on-disk) are handled as distinct concepts.
