It serves as a centralized, compile-time-safe reference for field identifiers—enabling consistent referencing across data access, UI binding, serialization, and validation layers—without relying on magic strings or hardcoded field names. --- ### 2. **Public Interface** The module exports a single public type: - **`TestSetupFields`** (`enum`) A fixed set of named constants representing metadata fields of a test setup. Each member corresponds to a logical column or property in a test setup entity: - `Name`: Identifier for the test setup. - `Description`: Human-readable description of the test setup. - `RecordingMode`: Specifies how data is recorded (e.g., continuous, triggered). - `PreTriggerSeconds`: Duration (in seconds) of data captured *before* a trigger event. - `PostTriggerSeconds`: Duration (in seconds) of data captured *after* a trigger event. - `LastModified`: Timestamp of the last modification. - `LastModifiedBy`: Identity (e.g., user ID or name) of the modifier. - `IsComplete`: Boolean flag indicating whether the test setup is finalized and ready for use. No methods, properties, or constructors are defined on the enum. --- ### 3. **Invariants** - The set of enum values is **immutable**—no fields may be added, removed, or renamed without updating all consumers. - Each value maps to a *semantic field* of a test setup; the enum itself does not enforce data types or nullability (e.g., `PreTriggerSeconds` is expected to be numeric, `IsComplete` boolean), but consumers must interpret values according to their documented semantics. - The enum values are **case-sensitive** and must match exactly (e.g., `"Name"` ≠ `"name"`) when used in string-based contexts (e.g., JSON property names, database column names). - The ordering of enum values is *not* semantically significant—iteration order should not be relied upon for correctness. --- ### 4. **Dependencies** - **Depends on**: None (no external assemblies or types are referenced in the source). - **Used by**: Implicitly, any module that handles test setup metadata (e.g., data mappers, UI view models, API request/response models, database schemas). While not visible in this file, typical consumers would include: - Data access layers (e.g., ORM mappings, query builders) - REST API controllers (e.g., for filtering, sorting, or field selection) - Frontend components (e.g., form fields, column headers) - Serialization/deserialization logic (e.g., JSON converters) --- ### 5. **Gotchas** - **No validation or default values**: The enum itself does not enforce constraints (e.g., `PreTriggerSeconds` ≥ 0, `IsComplete` only valid when `IsComplete == true`). Validation must be handled separately. - **String interoperability risk**: When used in JSON or database contexts, the enum’s underlying string representation (`"Name"`, `"RecordingMode"`, etc.) must be explicitly serialized (e.g., via `[JsonProperty("Name")]` or custom converters); otherwise, numeric values (0, 1, …) may be used, breaking compatibility. - **No extensibility**: Adding a new field requires recompiling *all* consumers—no backward-compatible extension mechanism is provided. - **Ambiguity in semantics**: The meaning of `RecordingMode` and `IsComplete` is not self-evident from the enum alone (e.g., what values does `RecordingMode` accept? What state does `IsComplete` reflect?). These require cross-referencing with related types (e.g., `RecordingMode` enum, test setup domain logic). *None identified beyond the above.*
