Tell us what’s happening:
My output seem good on terminal but still fail with testcase

Your code so far

function titleCase(str) {
  str = str.split(" ");
  var test= "";
  for (var i = 0; i < str.length; i++){
    test += str[i].charAt(0).toUpperCase() + str[i].slice(1).toLowerCase()+ " ";
  }
  return test;
}

titleCase("I'm a little tea pot AnD  jUsT pAssiNG thrOugh");

You have a trailing space at the end of the sentence so it does not pass the tests. You could use trim() to remove it. Another option would be to manipulate each word in the str array and then join them afterwards => str.join(' ').

The join function only separates each item. It does not append the separator to the end.
