Context

Context is passed to ContextConsumer functions during step execution. It is the action-facing view of the current run, providing access to configuration and fixture instances.

package org.paramixel.api;

public interface Context {
    Configuration configuration();
    <T> Optional<T> instance(Class<T> type);
    default <T> T requireInstance(Class<T> type);
    static <T> ContextConsumer withInstance(
            Class<T> type,
            InstanceConsumer<? super T> consumer);
}

Configuration access

var parallelism = context.configuration()
        .getInteger("paramixel.parallelism")
        .orElse(1);

Fixture access

Instance actions make fixture objects available through Context.

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

var verifyLogin = step(
        "verify login",
        Context.withInstance(Browser.class, browser -> browser.open("/login")));

Use context.instance(Type.class) when a fixture is optional. Use context.requireInstance(Type.class) or Context.withInstance(...) when the fixture is required.

Outcomes

Actions communicate outcomes by throwing Paramixel outcome exceptions such as FailException, SkipException, or AbortedException. The scheduler catches these and maps them to terminal Status values on the descriptor.
