Testing 2/2

Beispiel Test

#[cfg(test)]
mod tests {
  // Import the necessary modules
  use std::fs::OpenOptions;
  use std::io::Write;

  // This test writes to a file
  #[test]
  fn test_file() {
      // Opens the file ferris.txt or creates one if it doesn't exist.
      let mut file = OpenOptions::new()
          .append(true)
          .create(true)
          .open("ferris.txt")
          .expect("Failed to open ferris.txt");

      // Print "Ferris" 5 times.
      for _ in 0..5 {
          file.write_all("Ferris
".as_bytes())
              .expect("Could not write to ferris.txt");
      }
  }
