* CI: dev builds keep line tables only * CI: one integration-test binary per crate * CI: xtask runs tests with nextest, doctests apart, --keep-going on clippy and wasm cargo xtask test runs the workspace tests (--lib --bins --tests) with cargo-nextest when it is installed, else cargo test, then the doctests. cargo xtask ci uses the same two steps. * CI: docs name cargo xtask test * CI: agent guides name the moved fuzz test * CI: tests added on main join their crate's test binary
