Mock HTTP server with TLS support

I have a CLI application that does some http requests to user input dependant urls.

I used to test this using https://httpbin.org, but that is brittle and doesn'twork when there's no network connection (the site is also very slow right now for some reason).

So I switched to mockito, for a simple echo test server similar to httpbin's base64 endpoint.

fn setup_mockito_test_server() -> mockito::ServerGuard {    let mut server = mockito::Server::new();    server        .mock("GET", mockito::Matcher::Regex(r"^/echo/.*$".to_string()))        .with_status(200)        .with_header("content-type", "text/plain")        .with_body_from_request(|req| req.path()[6..].as_bytes().to_owned())        .create();    server}#[test]fn example_test() {    let server = setup_mockito_test_server();    let resp = reqwest::blocking::get(format!("{}/echo/foobar", server.url()))        .unwrap().text().unwrap();    assert_eq!(resp, "foobar");}

This works great, but to test some different code paths I need to use TLS (https).I did a quick google search but neither mockito, httpmocknor wiremockseem to support this out of the box.

How can I create an equivalent test server with HTTPS support?
