TestModule

1. Purpose

This module defines the foundational view and view-model interfaces for a Test Module within the DTS Viewer subsystem. Its purpose is to establish a contract for test-related UI components—specifically, to enable the display and management of loaded .NET assemblies (e.g., for dynamic test discovery or execution). It extends the base view/view-model abstractions (IBaseView, IBaseViewModel) to provide a standardized structure for test module UIs, ensuring separation of concerns between presentation logic and data.

2. Public Interface

ITestModuleView

public interface ITestModuleView : IBaseView { }

• Behavior: A marker interface representing the view (UI layer) for the test module. It inherits from IBaseView, implying it adheres to the common view contract (e.g., lifecycle management, binding context), though the exact members of IBaseView are not visible here. No additional members are defined in this interface.

ITestModuleViewModel

public interface ITestModuleViewModel : IBaseViewModel
{
    List<Assembly> AssemblyList { get; set; }
}

• Behavior: Represents the view model for the test module. It inherits from IBaseViewModel, implying standard view-model responsibilities (e.g., data binding, command handling). Its sole public member is AssemblyList, a mutable List<Assembly> property intended to hold the set of assemblies relevant to testing (e.g., test assemblies, dependencies). The property supports both read and write access, allowing replacement of the entire list.

3. Invariants

• ITestModuleView and ITestModuleViewModel must be used in conjunction (e.g., via MVVM binding), with ITestModuleView bound to an instance of ITestModuleViewModel.
• The AssemblyList property must be initialized to a non-null List<Assembly> before use (since it is a reference type with no default initialization in the interface).
• Assemblies in AssemblyList are expected to be loaded and valid (though the interface does not enforce this—consumers must handle ReflectionTypeLoadException, BadImageFormatException, etc., if applicable).
• No ordering guarantee is specified for AssemblyList; consumers must not assume any particular sequence unless enforced by the implementation.

4. Dependencies

• Depends on:
  • DTS.Common.Base.IBaseView and DTS.Common.Base.IBaseViewModel (base abstractions for view/view-model).
  • System.Collections.Generic (for List<T>).
  • System.Reflection (for Assembly).
• Depended on by:
  • Likely concrete implementations of test module views (e.g., WPF/WinForms controls) and view models (e.g., test assembly loader/view logic).
  • The DTS Viewer subsystem’s composition or DI container (to resolve ITestModuleView/ITestModuleViewModel pairs).
    (Exact dependents are not inferable from this source alone.)

5. Gotchas

• No validation on AssemblyList: The interface does not constrain the contents of AssemblyList (e.g., null assemblies, duplicate entries, non-test assemblies). Implementations must handle invalid entries.
• Mutable property: AssemblyList is a settable property, meaning external code can replace the entire list. This may cause unexpected UI updates if the view does not subscribe to change notifications (e.g., INotifyPropertyChanged—though not visible here, IBaseViewModel may or may not implement it).
• No test-specific semantics: Despite the name "TestModule", the interface provides no test-related functionality (e.g., test discovery, execution, filtering). All such behavior must reside in implementations.
• Namespace quirk: // ReSharper disable CheckNamespace suggests the namespace is intentionally DTS.Common.Interface (not nested under a TestModule sub-namespace), which may cause confusion in large solutions.
• None identified from source alone.
