A pattern has emerged where a integration tests check for the availability of an external tool (`git`, `taplo`, `gpg`, ...) and skip the test (by simply passing it) when it is not available. To check this, the program is run with the `--version` flag. Some tests require that the program be available at least when running in CI, by calling `ensure_running_outside_ci` conditionally on the outcome. The decision is up to each test, though, the utility merely returns a `bool`.
