SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Rust testing patterns provide a structured approach to writing unit, integration, async, and property-based tests, enabling TDD-inspired workflows and robust coverage for Rust projects.

Core Features & Use Cases

Unit tests with #[test] in a #[cfg(test)] module
Integration tests under tests/ with separate binaries
Async testing patterns using #[tokio::test] or async tests
Property-based testing with proptest
Mocking with mockall to isolate units

Quick Start

Write a minimal test to validate a simple function, then progressively add tests as you implement features.

FAQPage Schema

How do I structure Rust unit tests and integration tests in a project?▼

Rust unit tests belong in a #[cfg(test)] module within your source files, while integration tests are placed in a separate tests/ directory to run as independent binaries against your crate's public API.

What's the best way to mock dependencies in Rust testing?▼

Mocking dependencies in Rust testing is done using the mockall crate, which allows you to automatically generate mock implementations for traits to isolate units and verify interactions.

How do I test async Rust code effectively?▼

Async Rust testing is handled using the #[tokio::test] macro, which provides a runtime environment for executing and awaiting asynchronous functions within your test cases.

What is property-based testing in Rust and how do I apply it?▼

Property-based testing in Rust uses the proptest crate to generate arbitrary test inputs, ensuring your code holds true across a wide range of scenarios rather than just predefined cases.

Can I use rstest for parametrized Rust unit tests?▼

Yes, rstest allows you to define parametrized Rust unit tests, enabling you to run the same test logic against multiple inputs and fixtures for comprehensive coverage.

How do I maintain a TDD workflow in Rust?▼

A TDD workflow in Rust is maintained by writing minimal tests using #[test] first, implementing features to pass them, and progressively adding unit, integration, and property-based tests for robust coverage.
