Composition Building Blocks

Paramixel composes tests from action classes under org.paramixel.api.action. Each building block is built through a Builder and produces an immutable Action that can be nested into an action tree.

Common blocks

Building block	Purpose
Step	Execute a single context-aware operation.
Sequence	Execute child actions in order.
Parallel	Execute child actions concurrently.
Scope	Execute before/body/after with lifecycle guarantee (after always runs).
Static	Group static before/body/after work without fixture instance.
Instance	Create a fixture instance, run body, destroy instance.
Repeat	Repeat a child action.
Timeout	Bound child execution by a duration.
Assert	Evaluate a boolean condition against expected value.
Delay	Pause execution for a duration.
Each	Map iterables/streams into sequential or parallel child actions.

Fixture access

Context exposes fixture instances by type:

import org.paramixel.api.Context;
import org.paramixel.api.action.Step;

var verify = Step.of(
        "verify fixture",
        Context.withInstance(MyFixture.class, fixture -> fixture.verify()));

Use context.instance(Type.class) for an Optional or context.requireInstance(Type.class) when the fixture is required.
