cargo test

show output

By default rust will hide the stdout from your tests. You can show it with:

cargo test -- --show-output

consecutively

Tests are normally each run in their own thread. If you would like to instead run all the tests consecutively:

cargo test -- --test-threads=1

a single test

It's actually a pattern so you can use this to match any test which contains the name "add":

cargo test add

documentation

Build and open documentation provided by local dependencies.

cargo doc --open

show result of macro and #[derive] expansion

This can be done with the cargo-expand tool: cargo install cargo-expand

cargo expand
