Delightful integration tests in Rust
SMRTR summary
Rust lacks built-in test setup and teardown, making integration tests seem painful — but RAII and the testcontainers-rs crate change everything. By treating Docker containers as RAII resources, containers spin up automatically per test and clean up via Rust's Drop trait. The result is fully isolated, concurrent integration tests with RabbitMQ, Postgres, and Redis, all launched with a simple cargo test.
