SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Writing robust Rust tests can be verbose and brittle; this guide consolidates patterns and best practices for unit, integration, async, mocking, fixtures, property-based testing, and benchmarks to improve reliability and maintainability.

Core Features & Use Cases

  • Unit and integration tests written in idiomatic Rust, with clear Arrange-Act-Assert structure.
  • Async testing patterns using Tokio, including timeouts, concurrency, and deterministic timing strategies.
  • Mocking, fixtures, and property-based testing with Proptest; benchmarking with Criterion; and database testing with sqlx.

Quick Start

Write tests that exercise public interfaces, validate error paths, and run deterministically in isolated modules.

How do I write deterministic async tests in Rust with Tokio?

What's the best way to structure Rust unit and integration tests?

What's the best way to structure Rust unit and integration tests?

The best way to structure Rust unit and integration tests is organizing them into isolated modules with a clear Arrange-Act-Assert format. This approach ensures you validate error paths and exercise public interfaces effectively.

How does property-based testing work with Proptest in Rust?

Property-based testing with Proptest in Rust works by validating that certain properties hold true across a wide range of generated inputs. It helps uncover edge cases and error-path coverage that traditional example-based tests might miss.

Can I use Criterion for benchmarking Rust code?

Yes, you can use Criterion for benchmarking Rust code. Criterion provides reliable patterns for measuring performance improvements and regressions, ensuring your benchmarks are well-structured and statistically sound.

How do I safely test database interactions with sqlx in Rust?

To safely test database interactions with sqlx in Rust, apply patterns that ensure determinism and isolation. This involves managing test fixtures and database state so your tests do not interfere with each other or produce flaky results.
