reinhardt-testkit 0.4.0-alpha.10

//! Mock HTTP request and response utilities for server function testing.
//!
//! This module provides mock HTTP request/response types that can be used
//! to simulate HTTP interactions in server function tests.
//!
//! # Example
//!
//! ```rust,ignore
//! use reinhardt_testkit::server_fn::mock_request::{MockHttpRequest, MockHttpResponse};
//!
//! let request = MockHttpRequest::post("/api/users")
//!     .with_json(&CreateUserInput { name: "Alice".to_string() })
//!     .with_header("Authorization", "Bearer token");
//!
//! // Use request in server function testing
//! ```
