My file test common.test.mjs handle these tests:
1- ord Splitting: Verified that text is correctly split into individual words and that punctuation at the start or end of a word is ignored.
2- Proper Nouns: Confirmed that words starting with a capital letter are automatically marked as correct.
3- Dictionary Expansion: Tested that the addingWords function successfully updates the dictionary, allowing previously "incorrect" words to pass the check.
