The cargo test command has a --test
option that only runs a single "test target". What does "test target" mean? From my attempts to pass a valid argument it clearly isn't a test function. But I'm not really sure what the purpose of this argument is.
Test target is filename (without .rs extension) in tests/
directory.
cargo test --test foo
runs tests written in tests/foo.rs
.

It's for running a single integration test suite (files in test/
, or [[test]]
s declared in Cargo.toml).
You can filter the test functions in a test suite (including the suite that runs the unit tests defined in your library) by passing a pattern string as a positional argument to the test harness. (Use --
to delimit this from arguments to cargo
). All #[test]
functions whose qualified path contains the substring will be run.
cargo test -- it_works
cargo test -- some_mod::tests::x
