Staying One Undo Away from Green

TODO

☐

show stacking multiple dev tests and the functions where you keep adding new ones and forwarding the prior one to it

So, you end up with:

fn dev(input: String) -> String {
  return dev2(input)

  // original work here
}

fn dev2(input: String) -> String {
  return dev3(input)

  // original work from dev 2 here
}

fn dev3(input: String) -> String {
  let work_from_dev3= "ping".to_string();
  work_from_dev3
}

☐

Tests would look like this:

#[cfg(test)]
mod test {
  
  fn dev() {
    // show fiz
  }

  fn dev2() {
    // show buz
  }

  fn dev3() {
    // show whatever
  }
}
