# TestModule
|
|||
|
|
|
|||
|
|
## 1. Purpose
|
|||
|
|
This module defines the foundational view and view-model interfaces for a *Test Module* within the application’s viewer layer. It serves as a contract for UI components responsible for displaying and managing test-related functionality—specifically, operations involving .NET `Assembly` inspection or loading. The interfaces `ITestModuleView` and `ITestModuleViewModel` extend base abstractions (`IBaseView`, `IBaseViewModel`) to integrate into a larger MVVM (Model-View-ViewModel) architecture, enabling separation of UI presentation logic from business or test execution concerns.
|
|||
|
|
|
|||
|
|
## 2. Public Interface
|
|||
|
|
- **`ITestModuleView`**
|
|||
|
|
- *Signature*: `public interface ITestModuleView : IBaseView`
|
|||
|
|
- *Behavior*: A marker interface indicating a UI view (e.g., a WPF `UserControl`, WinForms `Form`, or equivalent) that hosts the test module’s UI. It inherits from `IBaseView`, implying it adheres to a common view contract (e.g., lifecycle management, data context binding), though the specifics of `IBaseView` are not provided here.
|
|||
|
|
|
|||
|
|
- **`ITestModuleViewModel`**
|
|||
|
|
- *Signature*: `public interface ITestModuleViewModel : IBaseViewModel`
|
|||
|
|
- *Behavior*: Defines the data and commands exposed to the `ITestModuleView`. It exposes a single property:
|
|||
|
|
- `AssemblyList`: A `List<Assembly>` (read-write) representing a collection of loaded .NET assemblies—likely those under test or available for test discovery/execution. The view model is responsible for populating and updating this list, and the view binds to it for display or interaction.
|
|||
|
|
|
|||
|
|
## 3. Invariants
|
|||
|
|
- `ITestModuleView` must be implemented by a concrete UI component that can bind to an `ITestModuleViewModel` instance (via `IBaseView`’s contract, assumed to include a `DataContext` or similar mechanism).
|
|||
|
|
- `ITestModuleViewModel.AssemblyList` must be non-null after initialization (implied by its read-write property definition), though the source does not specify whether it is initialized by default.
|
|||
|
|
- The `AssemblyList` property is expected to hold *loaded* `Assembly` instances (e.g., via `Assembly.Load*`), but the source does not define thread-safety, mutation semantics, or lifecycle constraints (e.g., whether assemblies may be unloaded or modified externally).
|
|||
|
|
|
|||
|
|
## 4. Dependencies
|
|||
|
|
- **Depends on**:
|
|||
|
|
- `DTS.Common.Base` namespace (specifically `IBaseView` and `IBaseViewModel`—behavior inferred but not defined here).
|
|||
|
|
- `System.Collections.Generic` (for `List<T>`).
|
|||
|
|
- `System.Reflection` (for `Assembly`).
|
|||
|
|
- **Depended on by**:
|
|||
|
|
- Concrete implementations of `ITestModuleView` (e.g., a WPF view class) and `ITestModuleViewModel` (e.g., a view model class handling test assembly management).
|
|||
|
|
- Likely consumed by a DI container or module loader in the `DTS.Common.Interface` layer to wire up test module UI components.
|
|||
|
|
|
|||
|
|
## 5. Gotchas
|
|||
|
|
- **Ambiguity in `AssemblyList` semantics**: The interface does not specify whether `AssemblyList` is *owned* by the view model (e.g., populated internally) or *observed* from an external source (e.g., shared state). This could lead to confusion about responsibility for assembly loading/unloading.
|
|||
|
|
- **No mutability guarantees**: The property is read-write, but there is no indication of whether changes to the list (e.g., `AssemblyList.Add(...)`) trigger UI updates (e.g., via `INotifyPropertyChanged`). If `IBaseViewModel` does not enforce change notification, consumers may need to manually raise events.
|
|||
|
|
- **No versioning or compatibility notes**: Given the proprietary context, future changes to `AssemblyList` (e.g., replacing `List<Assembly>` with `ImmutableArray<Assembly>`) could break implementations without warning.
|
|||
|
|
- **None identified from source alone** for other aspects (e.g., no obvious threading or disposal requirements).
