A suite of convenience methods and constructors for making requests to Iron Handlers.
extern crate iron;
extern crate iron_test;
use iron::prelude::*;
use iron::{Handler, Headers, status};
use iron_test::{request, response};
struct HelloWorldHandler;
impl Handler for HelloWorldHandler {
fn handle(&self, _: &mut Request) -> IronResult<Response> {
Ok(Response::with((status::Ok, "Hello, world!")))
}
}
#[test]
fn test_hello_world() {
let response = request::get("http://localhost:3000/hello",
Headers::new(),
&HelloWorldHandler).unwrap();
let result_body = response::extract_body_to_bytes(response);
assert_eq!(result_body, b"Hello, world!");
}The request API implements convenience methods for all the major HTTP verbs except CONNECT and TRACE. They're broken down as follows.
// Generates empty body
request::get<H: Handler>(path: &str, headers: Headers, handler: &H) -> IronResult<Response>
request::options<H: Handler>(path: &str, headers: Headers, handler: &H) -> IronResult<Response>
request::delete<H: Handler>(path: &str, headers: Headers, handler: &H) -> IronResult<Response>
request::head<H: Handler>(path: &str, headers: Headers, handler: &H) -> IronResult<Response>
// Accepts a `&str` body
request::post<H: Handler>(path: &str, headers: Headers, body: &str, handler: &H) -> IronResult<Response>
request::patch<H: Handler>(path: &str, headers: Headers, body: &str, handler: &H) -> IronResult<Response>
request::put<H: Handler>(path: &str, headers: Headers, body: &str, handler: &H) -> IronResult<Response>The requests that it makes sense for accept a &str body, while the other
requests generate an empty body for you. The request is passed directly to
the handle call on the Handler, and the raw result is returned to you.
For examples of testing different handlers, head over to the examples directory.
Sometimes it is useful to have a predefined directory layout with specific files in it. You can easily create a simple project directory using a ProjectBuilder.
Ex:
use iron_test::ProjectBuilder;
#[test]
fn test_a() {
let builder = ProjectBuilder::new("foo")
.file("index.html", "<html><h2>hello</h2></html>")
.file("main.css", "body{font-family: Verdana}");
builder.build();
// At this point you will have your project directory in:
// target/iron-integration-tests/test-<N>/foo/
}To access current project root, use p.root().
ProjectBuilder implements Drop and will clean up the project when it is dropped.
If you're using Cargo, just add iron-test to your Cargo.toml, and point it at the git url.
