Macro test_generator::test_expand_paths

test_expand_paths!() { /* proc-macro */ }

deprecated Generate a test-function call for each file matching the pattern

extern crate test_generator;
#[cfg(test)]
mod tests {
  test_generator::test_expand_paths! { test_exists; "res/*" }

  fn test_exists(dir_name: &str) { assert!(std::path::Path::new(dir_name).exists()); }
}

Assuming "res/*" expands to “res/set1”, and “res/set2” the macro will expand to

 mod tests {
    #[test]
    fn test_exists_res_set1() {
        test_exists("res/set1");
    }

    #[test]
    fn test_exists_res_set2() {
        test_exists("res/set2");
    }
 }
