 *Note*: These run integration tests that invoke `c2rust transpile`.

+Most tests are found in the [`tests`](../tests/) folder.

+Most tests can also be run with:
+
+```sh
+cargo nextest run
+```
+

+The tests in `tests/unit` can also be run manually using:

 ## Documentation
 
 Local documentation can be built with the normal `cargo doc` and `cargo doc --open`.

 ## What happens under the hood
 
 This `tests/unit` directory contains regression, feature, and unit tests. A test directory goes through the following set of steps:
