TinyBDD.dll

Coordinates the lifecycle of assembly-wide fixtures across the entire test assembly.

Remarks

This coordinator discovers all AssemblySetupAttribute declarations, instantiates the corresponding AssemblyFixture types, and manages their setup and teardown lifecycle.

The coordinator ensures that:

• Fixtures are initialized exactly once before any tests run.
• Fixtures are torn down exactly once after all tests complete.
• Multiple fixtures execute in registration order.
• Fixture state is accessible via GetFixture<T>().

This is a framework-agnostic singleton that integrates with xUnit, NUnit, and MSTest via their respective assembly fixture mechanisms.

Properties

Instance

Gets the singleton instance of the coordinator.

public static AssemblyFixtureCoordinator Instance { get; }

Property Value

AssemblyFixtureCoordinator

Methods

GetFixture<T>()

Retrieves a registered assembly fixture by type.

public static T GetFixture<T>() where T : AssemblyFixture

Returns

T

The registered instance of the fixture.

Type Parameters

T

The type of assembly fixture to retrieve.

Remarks

This method provides convenient access to assembly fixtures from within tests.

Exceptions

InvalidOperationException

Thrown if the fixture has not been registered or initialized.

InitializeAsync(Assembly, IBddReporter?, CancellationToken)

Discovers and initializes all assembly fixtures from the specified assembly.

public Task InitializeAsync(Assembly assembly, IBddReporter? reporter = null, CancellationToken ct = default)

Parameters

assembly Assembly

The assembly to scan for AssemblySetupAttribute declarations.

reporter IBddReporter

Optional reporter for Gherkin-style logging.

ct CancellationToken

Optional cancellation token.

Returns

Task

A task representing the asynchronous initialization operation.

Remarks

This method is idempotent - calling it multiple times has no effect after the first call.

TeardownAsync(CancellationToken)

Tears down all initialized assembly fixtures.

public Task TeardownAsync(CancellationToken ct = default)

Parameters

ct CancellationToken

Optional cancellation token.

Returns

Task

A task representing the asynchronous teardown operation.

Remarks

Fixtures are torn down in reverse order of their initialization. This method is idempotent - calling it multiple times has no effect after the first call.
