For myself, I'm not too much of a fan of us reusing like this as it hides in the test what is happening and gets annoying when you just need a little customization. Just directly publish the needed package inside of your test.

Package::new(name, vers)
.file("src/lib.rs", "")
.file(
"src/main.rs",
&format!("extern crate {}; fn main() {{}}", name),
)
.publish();
}

#[cargo_test]
fn simple() {
pkg("foo", "0.0.1");
