SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Rust testing can be tedious to implement, maintain, and scale across projects without a structured approach.

Core Features & Use Cases

  • Unit testing patterns: writing and organizing tests with #[test], modules, and helpful assertion macros.
  • Integration testing and test organization: using the tests/ directory and shared utilities.
  • Async testing: patterns for testing async code with Tokio or async-std.
  • Property-based testing: property-based tests with proptest to validate inputs.
  • Mocking and fakes: using mockall to mock dependencies and verify interactions.
  • Coverage guidance: using cargo-llvm-cov to measure and improve coverage toward targets.
  • Real-world use case: in a Rust project, structure tests to reflect production scenarios and ensure compilation with cargo test.

Quick Start

Run cargo test to begin applying TDD-oriented Rust testing across your project.

Frequently Asked Questions about rust-testing

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I structure Rust tests for unit and integration testing?▼

Test async Rust code by applying async testing patterns designed for the Tokio or async-std runtimes, ensuring your asynchronous functions are properly validated and executed deterministically.

What's the best way to mock dependencies and verify interactions in Rust?▼

Mock dependencies in Rust by using the mockall crate to generate mock implementations, allowing you to isolate components and verify that interactions between modules behave as expected.

Can I use property-based testing to validate Rust inputs automatically?▼

Property-based testing in Rust uses the proptest crate to automatically generate and validate a wide range of inputs, ensuring your code handles edge cases and maintains correctness across varied data.

How do I measure Rust code coverage with cargo-llvm-cov?▼

Measure Rust code coverage with cargo-llvm-cov to generate detailed reports, track untested code paths, and improve your project's test coverage toward measurable target goals.
