An example Tide unit test in Rust, with a Request and checked Response

tide_test.rs

#[cfg(test)]
mod tests {

 #[async_std::test]
    async fn index_page() -> tide::Result<()> {
	  use tide::http::{Url, Method, Request, Response};

      	  let mut app = tide::new();
      	  app.at("/").get(|_| async { Ok("Hello, world!") });
	  let url = Url::parse("https://example.com").unwrap();
	  let req = Request::new(Method::Get, url);
	  let mut res: Response = app.respond(req).await?;
	  assert_eq!("Hello, world", res.body_string().await?);
	  Ok(())
 }
