should handle toString -The toString method should return the correct hierarchy (no reply)

Question

I\'m working on a test and a lot of unit(hidden) tests were given , however I ran into this error with a block of my code. Can you all please help me out?

getStr         


        

Answer 1

I guess your test fails because you mix template literals and string concatenation, if you take e.g.:

 `${this._message} + "by" ${authorName}`

then a message will be inserted by the template:

`Heureka! + "by" Archimedes`

I guess it should rather be:

`${this._message} by ${authorName}`

Also repliedTo.authorName should be wrapped in ${...}

Answer 2

Try this... it worked for me

 getString(comment) {
    const authorName = comment.getAuthor().getName();
    if (!comment.getRepliedTo()) return authorName;
    return `${comment.getMessage()} by ${authorName} (replied to ${this.getString(comment.getRepliedTo())})`;
  }
  toString() {
   if(!this._repliedTo){
      return `${this._message} by ${this._author.getName()}`;
    } else {
      return `${this._message} by ${this._author.getName()} (replied to ${this._repliedTo.getAuthor().getName()})`
    }
  }
