For running doc tests setting the RUSTDOC env var to a shell script that runs rustdoc as sudo may work. You should probably unset it when using cargo doc though to prevent the generated documentation from being owned by root. For unit tests and integration tests you can set the CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_RUNNER (adapt for the target triple of your system) env var to "sudo" to run just the tests as root using sudo, but keep cargo running as regular user. The runner env var also applies to cargo run and cargo bench. See [1] for some basic documentation.
