# TestSetupsListViewModel Documentation

## 1. Purpose

`TestSetupsListViewModel` is the presentation logic component for the Test Setups List module in a WPF/Prism-based application. It manages the display, filtering, sorting, and selection of `ITestSetup` objects, serving as the intermediary between the view (`ITestSetupsListView`) and the underlying data. The class implements the MVVM pattern with `INotifyPropertyChanged` support and integrates with Prism's event aggregation and region management systems for decoupled communication across the application.
