+summary: Test cargo warning when publish to crates.io
+description: |
+  Downstreamed version of the upstream test publish_to_crates_io_warns:
+  https://github.com/rust-lang/cargo/blob/0.94.0/tests/testsuite/package.rs#L7741
+
+  Originally implemented in https://github.com/rust-lang/cargo/pull/16241
+
+  We need to downstream this test because koji builders don't have DNS resolving
+  to reach crates.io index. Hence, running this during the build will always
+  fail with an unexpected "Could not resolve host: index.crates.io" message.
