# TestModule
|
||
|
||
## 1. Purpose
|
||
This module defines the foundational view and view-model interfaces for a *Test Module* within the application’s viewer architecture. It serves as a contract layer enabling separation of concerns between UI presentation logic and business/test-specific concerns—specifically, managing a list of assemblies relevant to testing (e.g., test assemblies to be loaded, scanned, or executed). It extends the base `IBaseView` and `IBaseViewModel` interfaces, integrating into a larger MVVM (Model-View-ViewModel) or similar architectural pattern used across the codebase.
|
||
|
||
## 2. Public Interface
|
||
|
||
### `ITestModuleView`
|
||
```csharp
|
||
public interface ITestModuleView : IBaseView { }
|
||
```
|
||
- **Behavior**: A marker interface representing the *view* layer for the Test Module. It inherits from `IBaseView`, implying it adheres to a common view contract (e.g., lifecycle management, data binding support), though the specific members of `IBaseView` are not visible in this source. No additional API surface is defined here.
|
||
|
||
### `ITestModuleViewModel`
|
||
```csharp
|
||
public interface ITestModuleViewModel : IBaseViewModel
|
||
{
|
||
List<Assembly> AssemblyList { get; set; }
|
||
}
|
||
```
|
||
- **Behavior**: Represents the *view-model* for the Test Module. It exposes a single property, `AssemblyList`, which holds a list of `System.Reflection.Assembly` instances—likely representing test assemblies to be processed (e.g., loaded for test discovery, execution, or analysis). Inherits from `IBaseViewModel`, implying standard view-model responsibilities (e.g., property change notification via `INotifyPropertyChanged`), though concrete members of `IBaseViewModel` are not shown here.
|
||
|
||
## 3. Invariants
|
||
- `AssemblyList` must be a non-null `List<Assembly>` when accessed (enforced by the property’s `{ get; set; }` semantics), though null assignment is *syntactically* allowed by the interface. Implementation classes are expected to initialize it (e.g., to `new List<Assembly>()`) to avoid `NullReferenceException`.
|
||
- `ITestModuleView` and `ITestModuleViewModel` must be used in conjunction per the MVVM pattern—i.e., a concrete view should bind to a concrete view-model implementing `ITestModuleViewModel`.
|
||
- The `AssemblyList` is intended to hold *test-related* assemblies, though the interface does not enforce validation (e.g., no check for `Assembly.IsDynamic`, `Assembly.FullName`, or test-specific attributes). Implementation responsibility.
|
||
|
||
## 4. Dependencies
|
||
- **Depends on**:
|
||
- `DTS.Common.Base` (specifically `IBaseView`, `IBaseViewModel`)
|
||
- `System.Collections.Generic` (`List<T>`)
|
||
- `System.Reflection` (`Assembly`)
|
||
- **Depended on by**:
|
||
- Concrete implementations of `ITestModuleView` (e.g., WPF/WinForms/Xamarin views)
|
||
- Concrete implementations of `ITestModuleViewModel` (e.g., test module logic classes)
|
||
- Likely used by a DI container or view-model locator to resolve dependencies for the test module UI.
|
||
*(Exact consumers cannot be determined from this source alone.)*
|
||
|
||
## 5. Gotchas
|
||
- **No null-safety guarantee**: While `AssemblyList` is a read-write property, the interface does not enforce initialization. Consumers must ensure it is initialized before use.
|
||
- **No test-assembly validation**: The `AssemblyList` accepts *any* `Assembly` instances; invalid or non-test assemblies may be added silently. Validation (e.g., checking for test attributes or naming conventions) is not part of this interface.
|
||
- **No lifecycle or mutation notifications**: The interface does not expose events or methods to signal changes to `AssemblyList` (e.g., add/remove). If `IBaseViewModel` does not provide change notification, consumers may need to manually trigger updates.
|
||
- **Ambiguity of `IBaseView`/`IBaseViewModel`**: Without access to those base interfaces, the full contract (e.g., required methods, event handlers) remains unclear.
|
||
- **No threading guarantees**: `List<Assembly>` is not thread-safe; concurrent modifications require external synchronization (not specified here).
|
||
- **None identified from source alone.** |
