# Cairo Component Testing

## Overview
Show how to test components by embedding them into a mock contract and using dispatchers.

## Quick Use
- Read `references/component-testing.md` before answering.
- Build a minimal contract that embeds the component.
- Use the component interface dispatcher in tests.

## Response Checklist
- Embed component storage and events into the mock contract.
- Expose component functions via impl alias with `#[abi(embed_v0)]`.
- Use a dispatcher to call component entry points from tests.

## Example Requests
- "How do I write tests for a component?"
- "Do I need a full contract to test a component?"
- "How do I call component functions in tests?"
