TestFixture

Owns one fixture and runs its cleanup on explicit close, scope exit, or async-frame cancellation.

public class TestFixture<T, E>

constructor

Registers deterministic cleanup before the fixture is exposed to test code.

public constructor(value: T, cleanup: fun(T): Result<Unit, E>)

resource

Borrows the fixture value while this owner remains alive.

public get resource(): T

close

Executes cleanup once and returns the same outcome to repeated callers.

public fun close(): Result<Unit, E>
