datafusion/common/src/test_util.rs:233–238

Returns the arrow test data directory, which is by default stored in a git submodule rooted at `testing/data`. The default can be overridden by the optional environment variable `ARROW_TEST_DATA` panics when the directory can not be found. Example: ``` let testdata = datafusion_common::test_util::arrow_test_data(); let csvdata = format!("{}/csv/aggregate_test_100.csv", testdata); assert!(std::p

()

/// assert!(std::path::PathBuf::from(csvdata).exists());
/// ```
pub fn arrow_test_data() -> String {
    match get_data_dir("ARROW_TEST_DATA", "../../testing/data") {
        Ok(pb) => pb.display().to_string(),
        Err(err) => panic!("failed to get arrow data dir: {err}"),
    }
}
