prismetest

Prismetest is a hypothetical open-source testing framework designed for applications built with the Prism design pattern and the Prism libraries in the .NET ecosystem. It aims to provide a cohesive toolchain for authoring, organizing, and running tests across modular Prism projects, with an emphasis on test isolation, readable test code, and straightforward integration with common .NET testing libraries.

History and scope: The concept of prismetest emerged in community discussions focused on testing modular Prism applications in the early 2020s. A reference implementation appeared on a public repository in 2022, followed by ongoing contributions from independent developers and smaller maintainers. While not universally adopted, prismetest has been cited in discussions of test architecture for MVVM-based Prism apps and related frameworks.

Architecture and features: Prismetest offers a test discovery mechanism that aligns tests with Prism modules and regions, along with fixtures and data builders suitable for MVVM patterns. It supports unit and integration testing, using an assertion style compatible with familiar frameworks such as NUnit or xUnit. The framework provides a command-line interface and a programmatic API, enabling tests to be run locally or integrated into CI pipelines. Parallel test execution, customizable reporting (console, JSON, and HTML dashboards), and a plugin system for extending functionality are among its core features. It is designed to work with .NET 5/6+ and to integrate with existing test runners and build systems.

Usage: Developers install prismetest as a tool or library within their Prism-based projects and write tests in C# using attributes to designate test methods and Prism modules. The CLI is used to run tests and generate reports, while CI configurations can trigger automated test runs on build or release events.
