Function preroll::test_utils::assert_status

pub async fn assert_status<Status>(
    res: impl AsMut<Response>, 
    status: Status
) -> String where
    Status: TryInto<StatusCode>,
    Status::Error: Debug, 

Assert that a response has a specified status code and return the body as a string.

This helper has better assertion failure messages than doing this manually.

Example:

use preroll::test_utils::{self, assert_status, TestResult};

pub fn setup_routes(mut server: tide::Route<'_, std::sync::Arc<()>>) {
  // Normally imported from your service's crate (lib.rs).
}

#[async_std::main] // Would be #[async_std::test] instead.
async fn main() -> TestResult<()> {
    let client = test_utils::create_client((), setup_routes).await.unwrap();

    let mut res = client.get("/monitor/ping").await.unwrap();

    let body = assert_status(&mut res, 200).await;
    assert_eq!(body, "preroll_test_utils");
    Ok(())
}
