It is better to create the array variable after checking the condition

You don't say the language you're using, and also note that's the title of the tests, not the input value.

void main() {
  test("add", () { <- test title
    expect(duplicateCount(""), equals(0));
                          ^
                       input value of that test

The Basic test answers are wrong
for add the answer is meant to be 1 cuz only d is repeated but it shows me 2
for More tests the answer is meant to be 3 since e,s,and t are repeated but it shows me 2
