dir-diff

Are the contents of two directories different?

Mostly useful for integration-style tests when you want to check some generated output.

Example

Using dir-diff in an integration test with tempdir:

extern crate dir_diff;
extern crate tempdir;

#[test]
fn smoke_test() {
    let tmp_dir = TempDir::new("foo").expect("create temp dir failed");

    generate_some_stuff(&tmp_dir);

    assert!(!dir_diff::is_different(&tmp_dir.path(), "path/to/fixture").unwrap());
}
