By rewriting the tests, with rerast (https://github.com/google/rerast), to use the newly introduced "at" method. First I added the following temporary function to cargotest::support: pub fn project_foo() -> ProjectBuilder { project("foo") } Then I defined the following rewrite.rs: use cargotest::support::{ project, project_foo }; fn rule1(a: &'static str) { replace!(project("foo") => project_foo()); replace!(project(a) => project_foo().at(a)); } Then I ran rerast: cargo +nightly rerast --rules_file=rewrite.rs --force --targets tests --file tests/testsuite/main.rs Finally I searched and replaced the references to project_foo with argument-less project (a little awkardly on macOS with a git clean). find tests -type f -exec sed -i -e 's/project_foo/project/g' {} + git clean -d tests
