FEFF.TestFixtures.Engine

Core engine for the FEFF.TestFixtures solution.

About

Part of the FEFF.TestFixtures ecosystem — a framework-agnostic library for creating reusable test fixtures with scoped lifetimes. It replaces setup/teardown methods and the disposable pattern on test classes with composable, dependency-injected fixtures that can be shared across test projects. See the main README for full documentation.

This Package

This package is the engine that powers the entire fixture system. It is test-framework-agnostic and can be used standalone or through a test-framework integration package.

Key components:

Type Description
FixtureManager Creates, memoizes, and disposes fixtures within scopes
FixtureManagerBuilder Configures and builds a FixtureManager
IFixtureScope Interface for resolving fixtures within a scoped lifetime

The engine discovers fixture classes via reflection (types marked with [Fixture] or implementing IFixtureRegistrar) and manages their lifecycle, dependency injection, and disposal.

You typically don't reference this package directly — use a test-framework integration package instead (e.g., FEFF.TestFixtures.XunitV3 or FEFF.TestFixtures.TUnit). The integration packages will automatically include this engine as a dependency.
