Rust Testing Patterns

Write comprehensive tests for Rust applications using unit, integration, and property-based testing.

Usage

Share code you want to test or ask about testing strategies for guidance on test design.

Examples

  • "How do I test async functions in Rust?"
  • "Set up property-based testing with proptest"
  • "What's the best way to mock external dependencies?"

Guidelines

  • Cover unit tests, integration tests, and doc tests
  • Show how to test error conditions and edge cases
  • Include async testing patterns with tokio::test
  • Recommend mockall for trait-based mocking
  • Explain test organization and naming conventions
