# Diagnostics
|
||
|
|
|
||
|
|
### 1. **Purpose**
|
||
|
|
This module defines the core interfaces (`IDiagnosticsTreeView` and `IDiagnosticsViewModel`) for a diagnostics view-model/view architecture within the test setup diagnostics subsystem. It establishes a contract for a MVVM-style pairing where `IDiagnosticsViewModel` manages the logic and state for diagnostics presentation, while `IDiagnosticsTreeView` represents the UI layer (likely a tree-structured control for displaying hierarchical diagnostic data). The interfaces extend base abstractions (`IBaseView`, `IBaseViewModel`) to integrate with a larger framework for test setup UI components.

### 2. **Public Interface**
|
||
|
|
|
||
|
|
#### `IDiagnosticsTreeView`
|
||
|
|
- **Signature**: `public interface IDiagnosticsTreeView : IBaseView { }`
|
||
|
|
- **Behavior**: Represents the view layer for diagnostics UI. As a marker interface extending `IBaseView`, it implies conformance to a base view contract (e.g., lifecycle, binding, or rendering responsibilities), but no additional members are defined in this source. Its purpose is to serve as a strongly-typed reference for the view in the view-model.
|
||
|
|
|
||
|
|
#### `IDiagnosticsViewModel`
|
||
|
|
- **Signature**: `public interface IDiagnosticsViewModel : IBaseViewModel`
|
||
|
|
- **Property**: `IDiagnosticsTreeView View { get; set; }`
|
||
|
|
- Gets or sets the associated view instance. Enables two-way binding or view-view-model coordination.
|
||
|
|
- **Method**: `void Unset();`
|
||
|
|
- Releases or clears the view reference (likely to break circular references, prepare for disposal, or reset state). Behavior is not further specified beyond its signature.
|
||
|
|
|
||

|
### 3. **Invariants**
|
||
|
|
- `IDiagnosticsViewModel.View` must be assignable to an instance implementing `IDiagnosticsTreeView`.
|
||
|
|
- The `Unset()` method is expected to clear or invalidate the `View` reference (e.g., set it to `null`), though the exact behavior is not specified in the source.
|
||
|
|
- Both interfaces inherit from base interfaces (`IBaseView`, `IBaseViewModel`), implying adherence to their respective contracts (e.g., lifecycle management, data binding support), but those are defined externally and not detailed here.
|
||
|
|
- *No validation rules, ordering guarantees, or state constraints are explicitly defined in the provided sources.*
|
||

### 4. **Dependencies**
|
||
|
|
- **Internal Dependencies**:
|
||
|
|
- `DTS.Common.Base` namespace (specifically `IBaseView` and `IBaseViewModel`).
|
||
|
|
- **External Dependencies**:
|
||
|
|
- `IDiagnosticsTreeView` and `IDiagnosticsViewModel` are likely consumed by concrete implementations (e.g., `DiagnosticsViewModel : IDiagnosticsViewModel`) and a DI/container or view-hosting layer (e.g., WPF/WinForms UI framework).
|
||
|
|
- The module is part of `DTS.CommonCore`, suggesting it is a shared dependency for test setup diagnostics components across the codebase.
|
||
|
|
- **Dependents**: Not explicitly stated, but any diagnostics UI module (e.g., a diagnostics window or panel) would depend on these interfaces for decoupled view-model binding.
|
||
|

|
### 5. **Gotchas**
|
||
|
|
- **Ambiguity in `Unset()` semantics**: The interface does not specify whether `Unset()` disposes resources, nullifies the `View` property, or triggers cleanup events. Implementers must infer or document this behavior.
|
||
|
|
- **No explicit event or data-binding contract**: While `IBaseViewModel` likely implies change notification (e.g., `INotifyPropertyChanged`), this is not confirmed here. Consumers should verify base interface contracts.
|
||
|
|
- **Minimal interface surface**: The interfaces are intentionally thin (likely to reduce coupling), but this means critical behavior (e.g., how diagnostics data is loaded or updated) is deferred to implementations.
|
||
|
|
- **None identified from source alone.**
