cargo-test

cargo-test is a command for coding agents from olorehq/olore. It costs 0 tokens per session (7,258 once invoked), scanned A, original, MIT.

A command for Rust projects that compiles and runs unit tests, integration tests, and documentation tests. Rust is a programming language, and Cargo is its build and package tool.

In plain words
What is it for?
Use it to run all tests in a package, filter tests by name, pass options to the test program, or control how many tests run in parallel.
Why use it?
It provides one standard way to verify that a Rust package still works and to run only tests matching a selected name.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cargo-test scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

NAME

cargo-test --- Execute unit and integration tests of a package

SYNOPSIS

cargo test [options] [testname] [-- test-options]

DESCRIPTION

Compile and execute unit, integration, and documentation tests.

The test filtering argument TESTNAME and all the arguments following the two dashes (--) are passed to the test binaries and thus to libtest (rustc's built in unit-test and micro-benchmarking framework). If you're passing arguments to both Cargo and the binary, the ones after -- go to the binary, the ones before go to Cargo. For details about libtest's arguments see the output of cargo test -- --help and check out the rustc book's chapter on how tests work at https://doc.rust-lang.org/rustc/tests/index.html.

As an example, this will filter for tests with foo in their name and run them on 3 threads in parallel:

cargo test foo -- --test-threads 3

Tests are built with the --test option to rustc which creates a special executable by linking your code with libtest. The executable automatically runs all functions annotated with the #[test] attribute in multiple threads. #[bench] annotated functions will also be run with one iteration to verify that they are functional.

If the package contains multiple test targets, each target compiles to a special executable as aforementioned, and then is run serially.

The libtest harness may be disabled by setting harness = false in the target manifest settings, in which case your code will need to provide its own main function to handle running tests.

Documentation tests

Documentation tests are also run by default, which is handled by rustdoc. It extracts code samples from documentation comments of the library target, and then executes them.

Different from normal test targets, each code block compiles to a doctest executable on the fly with rustc. These executables run in parallel in separate processes. The compilation of a code block is in fact a part of test function controlled by libtest, so some options such as --jobs might not take effect. Note that this execution model of doctests is not guaranteed and may change in the future; beware of depending on it.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cargo-test is a command published in the GitHub repository olorehq/olore (103 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 7,258 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
