cargo-auto-test

   2 # Run `cargo test` on an installed Debian crate, e.g. in an autopkgtest.

   4 # Requires dev-dependencies to be installed. If you give extra flags such as
   5 # "--all-features", then these features' dependencies must also be installed.
   6 #
   7 # This script also swallows some known false-positive test failures, so you
   8 # don't have to set test_is_broken everywhere in your debcargo.toml configs.
