Implement Testing for Trigram Model

[Cpgeragh]

Description: Develop tests to verify the correctness of each function, including text preprocessing and trigram generation.

Checklist:

• [ ] Research testing strategies for NLP models, especially n-gram models.
• [x] Write sample test cases for the text preprocessing function (e.g., check for uppercase conversion and character removal).
• [x] Write test cases for trigram generation to verify that the correct trigrams are generated from sample input.
• [ ] Verify that smoothing is applied correctly in the trigram model.
• [ ] Run tests to confirm that all functions behave as expected and handle edge cases.
