How can I test a local clippy version?

[tisonkun]

When debugging #7479, I clone this repo and build my own clippy-driver and cargo-clippy. After passing the DYLD_LIBRARY_PATH it can run with -h but fail with:

$ DYLD_LIBRARY_PATH=/Users/tison/.rustup/toolchains/nightly-2023-07-28-aarch64-apple-darwin/lib/rustlib/aarch64-apple-darwin/lib  ~/Brittani/rust-clippy/target/debug/cargo-clippy
error: process didn't exit successfully: `/Users/tison/.rustup/toolchains/nightly-2023-08-01-aarch64-apple-darwin/bin/rustc -vV` (signal: 6, SIGABRT: process abort signal)
--- stderr
dyld[68457]: missing symbol called

I wonder if there is a smooth way to test a local compile clippy like cargo clippy --binpath ... or alternative I can test out my modifications.

cargo dev lint file.rs or cargo dev lint /path/to/crate to either lint a file or an entire crate with your local changes to Clippy.

When submitting a PR you'll have to submit a standalone test in tests/ui though. You can run only a single test with TESTNAME=your_test_file_name cargo uitest.
