substreams-testing

What problem does it solve?

This skill provides expert strategies and patterns for designing, executing, and validating Substreams tests, reducing debugging time and increasing reliability across unit, integration, and performance scenarios.

Core Features & Use Cases

• Test design templates: reusable unit and integration test patterns for Substreams modules.
• Performance testing patterns: load testing and parallel execution validation with realistic blocks.
• Test data orchestration: building fixtures, mocks, and synthetic data to cover edge cases.

Quick Start

Start by creating a starter Rust test scaffold for a Substreams module that maps transfers, then run unit tests, integration tests, and a basic performance benchmark.
