lmrc-cli 0.3.16

//! Integration tests for the example users API
//!
//! These tests demonstrate how to test your API endpoints end-to-end.
//!
//! ## Running Tests
//!
//! ```bash
//! # Make sure test database is running
//! docker-compose up -d postgres
//!
//! # Run tests
//! cargo test
//!
//! # Run only integration tests
//! cargo test --test integration_test
//! ```
//!
//! ## Test Database Setup
//!
//! For integration tests, you should:
//! 1. Use a separate test database
//! 2. Run migrations before tests
//! 3. Clean up after each test
//!
//! Consider using `sqlx::test` macro or a test fixture library.
