cargo test

Execute the unit and integration tests of a Rust package. More information: https://doc.rust-lang.org/cargo/commands/cargo-test.html.

• Only run tests containing a specific string in their names:

cargo {{[t|test]}} {{test_name}}

• Set the number of simultaneous running test cases:

cargo {{[t|test]}} -- --test-threads {{count}}

• Test artifacts in release mode, with optimizations:

cargo {{[t|test]}} {{[-r|--release]}}

• Test all packages in the workspace:

cargo {{[t|test]}} --workspace

• Run tests for a specific package:

cargo {{[t|test]}} {{[-p|--package]}} {{package}}

• Run tests without hiding output from test executions:

cargo {{[t|test]}} -- --nocapture
