Macro test_generator::glob_expand

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

deprecated Function-Attribute macro expanding glob-file-pattern to a list of directories and generating a test-function for each one.

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

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

The macro will expand the code for each subfolder in "res/*", generating the following code. This code is not visible in IDE. Every build-time, the code will be newly generated.

 #[cfg(test)]
 mod tests {
    #[test]
    fn gen_res_set1() {
        test_exists("res/testset1");
    }

    #[test]
    fn gen_res_set2() {
        test_exists("res/testset2");
    }
 }
