# TestModule
|
|||
|
|
|
|||
|
|
## 1. Purpose
|
|||
|
|
This module defines the core view and view-model interfaces for a test-related UI component within the DTS system. It serves as a contract layer separating UI presentation logic (via `ITestModuleView`) from its data-binding and state management (via `ITestModuleViewModel`), enabling test module implementations to integrate with the broader DTS framework’s MVVM (Model-View-ViewModel) architecture. It extends base abstractions (`IBaseView`, `IBaseViewModel`) to provide a standardized extension point for test-specific UI functionality—though the interfaces themselves are minimal and intentionally leave implementation details to concrete consumers.
|
|||
|
|
|
|||
|
|
## 2. Public Interface
|
|||
|
|
|
|||
|
|
### `ITestModuleView`
|
|||
|
|
- **Signature**: `public interface ITestModuleView : IBaseView { }`
|
|||
|
|
- **Behavior**: Marks a UI view class as belonging to the test module. Inherits from `IBaseView` (defined in `DTS.Common.Base`), but adds no additional members. Its sole purpose is type-based identification and framework integration (e.g., for dependency injection, view discovery, or navigation).
|
|||
|
|
|
|||
|
|
### `ITestModuleViewModel`
|
|||
|
|
- **Signature**: `public interface ITestModuleViewModel : IBaseViewModel { List<Assembly> AssemblyList { get; set; } }`
|
|||
|
|
- **Behavior**: Represents the view-model for the test module. Extends `IBaseViewModel` and exposes a single property, `AssemblyList`, which holds a list of `Assembly` instances (from `System.Reflection`). This list is likely used to enumerate or inspect test assemblies at runtime (e.g., for test discovery, loading, or execution). The property is read-write, implying the view-model is responsible for both consuming and potentially updating the list.
|
|||
|
|
|
|||
|
|
## 3. Invariants
|
|||
|
|
- `ITestModuleView` and `ITestModuleViewModel` must be implemented together in a valid MVVM pairing (e.g., a view and its corresponding view-model).
|
|||
|
|
- `AssemblyList` in `ITestModuleViewModel` must be non-null (as it is a non-nullable reference type in C# 8+ with enabled annotations), though the source does not explicitly enforce initialization. Implementations must ensure it is initialized before use to avoid `NullReferenceException`.
|
|||
|
|
- The `AssemblyList` property is expected to contain only valid `Assembly` instances (e.g., loaded test assemblies), though no validation is performed by the interface itself.
|
|||
|
|
- No ordering or uniqueness guarantees are specified for `AssemblyList`; implementations may assume arbitrary order and potential duplicates unless otherwise constrained by consuming code.
|
|||
|
|
|
|||
|
|
## 4. Dependencies
|
|||
|
|
- **Depends on**:
|
|||
|
|
- `DTS.Common.Base` (specifically `IBaseView` and `IBaseViewModel`, though their definitions are not provided here).
|
|||
|
|
- `System.Collections.Generic` (for `List<T>`).
|
|||
|
|
- `System.Reflection` (for `Assembly`).
|
|||
|
|
- **Depended on by**:
|
|||
|
|
- Unknown from this source alone. Likely consumed by:
|
|||
|
|
- A test module implementation (e.g., `TestModuleView`, `TestModuleViewModel` classes).
|
|||
|
|
- A DI container or view-resolution framework (e.g., to bind views to view-models).
|
|||
|
|
- Test orchestration or discovery services that operate on `ITestModuleViewModel` instances.
|
|||
|
|
|
|||
|
|
## 5. Gotchas
|
|||
|
|
- **Ambiguity in `AssemblyList` semantics**: The purpose of `AssemblyList` is not documented—e.g., whether it represents *loaded* test assemblies, *candidate* assemblies for loading, or assemblies to be *unloaded*. Its mutability (`set` accessor) suggests external code may replace the entire list, but this is not guaranteed to be thread-safe.
|
|||
|
|
- **No lifecycle management**: The interfaces provide no methods for initialization, cleanup, or state transitions (e.g., `Load`, `Unload`, `ExecuteTest`). These are likely handled by `IBaseViewModel` or external orchestrators, but this is not explicit here.
|
|||
|
|
- **Minimal interface surface**: The interfaces are intentionally sparse, which may indicate they are placeholders for future expansion or that test-specific logic resides elsewhere (e.g., in concrete implementations or extension methods).
|
|||
|
|
- **No nullability annotations**: While `List<Assembly>` is non-nullable, the list *elements* are not annotated for nullability. Implementations must decide whether `null` assemblies are permitted (likely not).
|
|||
|
|
- **None identified from source alone.**
