Can the client send a file?

[fractal-joe]

Something like:

#[tokio::test]
async fn test_uploads_workbook_and_gets_topics() {
    let client = Client::tracked(app()).await.unwrap()

    let mut file = File::open("tests/fixtures/test.xlsx").unwrap();

    let actual = client.post("/upload-workbook")
        .body(file) //  <---- The trait bound `std::fs::File: std::convert::AsRef<[u8]>` is not satisfied
        .dispatch()
        .await;

    assert_eq!(actual.status(), rocket::http::Status::Created);
}

The File struct doesn't actually have the file contents. If you want to get the contents of the file, you can use one of the std::io::Read (link) methods (i.e. read_to_end). Then you can send that data in your request.
