# TestModule

## 1. Purpose  
This module defines the core view and view model interfaces for a test-related UI component within the DTS system. It establishes the contract between the presentation layer (`ITestModuleView`) and its data-binding context (`ITestModuleViewModel`), enabling separation of concerns for test module functionality—likely used for dynamic test assembly loading, discovery, or execution orchestration. The interfaces inherit from base abstractions (`IBaseView`, `IBaseViewModel`) to integrate consistently with the broader UI framework.

## 2. Public Interface  

### `ITestModuleView`  
- **Signature**: `public interface ITestModuleView : IBaseView`  
- **Behavior**: Represents the view layer for the test module. As a marker interface inheriting `IBaseView`, it signals conformance to the base view contract (e.g., lifecycle management, UI binding setup), but no additional members are defined here. Concrete implementations would be responsible for rendering test-related UI and delegating user interactions to the view model.

### `ITestModuleViewModel`  
- **Signature**: `public interface ITestModuleViewModel : IBaseViewModel`  
- **Behavior**: Represents the view model for the test module. It exposes a single property `AssemblyList`, which holds a list of `Assembly` objects—likely representing dynamically loaded test assemblies for discovery or execution. The property is read-write (`get; set;`), implying the view model supports both initialization and runtime replacement of the assembly list.

## 3. Invariants  
- `ITestModuleView` must be implemented by a class that adheres to the contract of `IBaseView` (behavior of which is defined externally, not in these files).  
- `ITestModuleViewModel` must be implemented by a class that adheres to `IBaseViewModel` *and* provides a `List<Assembly>` property named `AssemblyList`.  
- The `AssemblyList` property must be assignable to `null` or a non-null `List<Assembly>` (no constraints on contents are specified in the interface).  
- No ordering, deduplication, or null-safety guarantees are enforced by the interface for `AssemblyList`.

## 4. Dependencies  
- **Depends on**:  
  - `DTS.Common.Base` (specifically `IBaseView`, `IBaseViewModel`)  
  - `System.Collections.Generic` (for `List<T>`)  
  - `System.Reflection` (for `Assembly`)  
- **Depended on by**:  
  - Any UI framework or DI container wiring code that binds views to view models (e.g., a test module presenter or controller).  
  - Concrete implementations (e.g., `TestModuleView : ITestModuleView`, `TestModuleViewModel : ITestModuleViewModel`)—not visible in this source.  
  - Likely consumed by higher-level modules managing test execution or test discovery workflows.

## 5. Gotchas  
- The interface `ITestModuleView` is empty beyond inheritance—its purpose is purely contractual; implementation details (e.g., event handlers, UI controls) are not specified here.  
- `AssemblyList` is exposed as a mutable `List<Assembly>`; callers may mutate the list directly (e.g., via `.Add()`, `.Clear()`), which could lead to race conditions or unexpected side effects if accessed concurrently without external synchronization.  
- No validation is defined for the assemblies in `AssemblyList` (e.g., no requirement that they be test assemblies or implement specific interfaces).  
- The `Assembly` type is used directly—no abstraction (e.g., `ITestAssembly`) is provided, coupling the view model to .NET reflection semantics.  
- None identified from source alone.
