yup-hyper-mock

hyper-mock is a utility library to help hyper clients with their testing. It provides types used to test hyper itself, most notably, mock connections and macros to ease their use.

Usage

Set it up for use in tests in Cargo.toml

[dev-dependencies]
yup-hyper-mock = "*"
log = "*"  # log macros are used within yup-hyper-mock

In your tests module

#[cfg(test)]
mod tests {
    use hyper;
    use hyper_util::client::legacy::Client;

    yup_hyper_mock::mock_connector!(MockRedirectPolicy {
        "http://127.0.0.1" =>       "HTTP/1.1 301 Redirect\r\n\
                                     Location: http://127.0.0.2\r\n\
                                     Server: mock1\r\n\
                                     \r\n\
                                    "

                                     Server: mock3\r\n\
                                     \r\n\
                                    "
