To write effective unit tests, first your code should be testable. To have a testable piece of code first you should separate the business from UI. In this way you can test your business via unit testing. Also if you use MVVM patterns you can test your UI logic independently from your UI technology.

The common of unit testing steps is. Arrange -> Act -> Assert In my opinion, I should write your code in separate method to validate. The method will return true or false. It's easy to check and unit testing. regards.

public bool ValidateInput(string input)
{
  Regex Rx = new Regex(@"^[\p{L} \.'\-]{0,20}$");
  Match match = rx.Match(input);
  if(match.Success) return true;
  return false;
}
// To call the method.
public void Testing(){
  string userName = "your user name";
  if(ValidateInput(userName))
    MessageBox.Show("Your username incorrect.");
  else{
    // Todo something.
  }
}
