//
// To run tests while enabling printing to stdout/stderr
//
// RUST_LOG=info cargo test --test basic_auth -- --show-output
//
// What happens in this test:
//
// - Start an axum HTTP server that serves the manifest and our media segments. The server is
// configured to require HTTP Basic authorization.
//
// - Fetch the associated media content using dash-mpd-cli via "cargo run", and check that each of
// the expected remote elements is retrieved.
