# Documentation: Test Settings Interfaces

## 1. Purpose
This module defines the contractual interfaces for the "Test Settings" feature within an MVVM (Model-View-ViewModel) architecture. It provides `ITestSettingsView` and `ITestSettingsViewModel` to decouple the UI layer from the business logic layer. These interfaces serve as markers for dependency injection and view resolution, ensuring that specific Test Settings components can be identified and managed by the system's core infrastructure.

## 2. Public Interface

### `ITestSettingsView`
*   **Signature:** `public interface ITestSettingsView : IBaseView`
*   **Namespace:** `DTS.Common.Interface`
*   **Description:** Represents the View component for Test Settings. It inherits from `IBaseView` but defines no additional members, functioning as a specific marker interface for the system's view resolution mechanism.

### `ITestSettingsViewModel`
*   **Signature:** `public interface ITestSettingsViewModel : IBaseViewModel`
*   **Namespace:** `DTS.Common.Interface`
*   **Description:** Represents the ViewModel component for Test Settings. It inherits from `IBaseViewModel` but defines no additional members, functioning as a specific marker interface for the system's logic layer.

## 3. Invariants
*   **Hierarchy:** Any class implementing `ITestSettingsView` must also implement `IBaseView`. Any class implementing `ITestSettingsViewModel` must also implement `IBaseViewModel`.
*   **Structure:** These interfaces are currently empty (marker interfaces). Therefore, they do not enforce specific method signatures or properties beyond those inherited from their base types.

## 4. Dependencies
*   **External Dependencies:**
    *   `DTS.Common.Base`: Required for the definitions of `IBaseView` and `IBaseViewModel`.
*   **Consumers:**
    *   Concrete View implementations (e.g., WPF Windows/Pages) needing to register as the Test Settings UI.
    *   Concrete ViewModel implementations handling the logic for Test Settings.
    *   Dependency injection containers or navigation services that resolve these specific interfaces.

## 5. Gotchas
*   **Marker Interfaces:** Both interfaces are empty. While they likely facilitate type-safe navigation or injection, they expose no specific API surface (e.g., `LoadSettings()` or `SaveCommand`) themselves. Developers must cast to the concrete implementation or a more specific base type to access actual functionality, or rely on members exposed by `IBaseView`/`IBaseViewModel`.
*   **Base Behavior Unknown:** The actual capabilities of these interfaces depend entirely on the definitions of `IBaseView` and `IBaseViewModel` found in `DTS.Common.Base`, which are not included in the provided source.
