Introduction

In the world of movie streaming and downloading, it's not uncommon for users to encounter missing movies. This can be due to various reasons such as the movie not being available on the Hard Disk Drive (HDD) or the popular torrent site, YTS. In this article, we'll delve into the implementation of logic to handle cases where the movie is neither on the HDD nor YTS. We'll explore the acceptance criteria, checklist, and provide a step-by-step guide on how to implement this feature.

Acceptance Criteria

Before we dive into the implementation, let's review the acceptance criteria for this feature:

Given

A movie title is provided.

When

The movie is not found in the HDD or YTS.

Then

Return a message indicating the movie is unavailable.

Checklist

To ensure we cover all the necessary steps, let's go through the checklist:

Add a response field for "not found" cases

We need to add a response field to handle cases where the movie is not found in the HDD or YTS.

Write unit tests for this scenario

We'll write unit tests to ensure our implementation is correct and handles the "not found" cases as expected.

Implementation

To implement the logic for handling missing movie cases, we'll follow these steps:

Step 1: Add a response field for "not found" cases

We'll add a new response field to our existing codebase to handle cases where the movie is not found in the HDD or YTS. This field will be used to return a message indicating the movie is unavailable.

class MovieResponse:
    def __init__(self, movie_title, found_on_hdd=False, found_on_yts=False):
        self.movie_title = movie_title
        self.found_on_hdd = found_on_hdd
        self.found_on_yts = found_on_yts

    def get_response(self):
        if self.found_on_hdd or self.found_on_yts:
            return f"Movie '{self.movie_title}' found on HDD or YTS."
        else:
            return f"Movie '{self.movie_title}' not found on HDD or YTS."

Step 2: Write unit tests for this scenario

We'll write unit tests to ensure our implementation is correct and handles the "not found" cases as expected. We'll use the unittest framework to write our tests.

import unittest
from movie_response import MovieResponse

class TestMovieResponse(unittest.TestCase):
    def test_found_on_hdd(self):
        movie_response = MovieResponse("The Shawshank Redemption", found_on_hdd=True)
        self.assertEqual(movie_response.get_response(), "Movie 'The Shawshank Redemption' found on HDD or YTS.")

    def test_found_on_yts(self):
        movie_response = MovieResponse("The Shawshank Redemption", found_on_yts=True)
        self.assertEqual(movie_response.get_response(), "Movie 'The Shawshank Redemption' found on HDD or YTS.")

    def test_not_found_on_hdd_or_yts(self):
        movie_response = MovieResponse("The Shawshank Redemption")
        self.assertEqual(movie_response.get_response(), "Movie 'The Shawshank Redemption' not found on HDD or YTS.")

if __name__ == "__main__":
    unittest.main()

Conclusion

In this article, we implemented logic to handle cases where the movie is neither on the HDD nor YTS. We added a response field to handle "not found" cases and wrote unit tests to ensure our implementation is correct. By following these steps, we can ensure that our movie streaming or downloading application handles missing movie cases correctly and provides a better user experience.

Future Improvements

There are several ways to improve this implementation:

Add more error handling: We can add more error handling to handle cases where the movie is not found in the HDD or YTS due to other reasons such as network issues or database errors.
Implement caching: We can implement caching to store the results of previous searches and reduce the number of requests to the HDD or YTS.
Use a more robust search algorithm: We can use a more robust search algorithm to search for movies on the HDD or YTS and reduce the number of false negatives.

Introduction

In our previous article, we implemented logic to handle cases where the movie is neither on the Hard Disk Drive (HDD) nor YTS. We added a response field to handle "not found" cases and wrote unit tests to ensure our implementation is correct. In this article, we'll answer some frequently asked questions (FAQs) related to handling missing movie cases.

Q&A

Q: What is the purpose of handling missing movie cases?

A: The purpose of handling missing movie cases is to provide a better user experience by returning a meaningful message when a movie is not found on the HDD or YTS.

Q: How do I implement the logic for handling missing movie cases?

A: To implement the logic for handling missing movie cases, you need to add a response field to handle "not found" cases and write unit tests to ensure your implementation is correct.

Q: What are the benefits of handling missing movie cases?

A: The benefits of handling missing movie cases include:

Providing a better user experience by returning a meaningful message when a movie is not found on the HDD or YTS.
Reducing the number of false negatives by implementing a more robust search algorithm.
Improving the overall performance of the application by reducing the number of requests to the HDD or YTS.

Q: How do I handle cases where the movie is not found in the HDD or YTS due to other reasons such as network issues or database errors?

A: To handle cases where the movie is not found in the HDD or YTS due to other reasons such as network issues or database errors, you need to add more error handling to your implementation.

Q: Can I use a more robust search algorithm to search for movies on the HDD or YTS?

A: Yes, you can use a more robust search algorithm to search for movies on the HDD or YTS. This can help reduce the number of false negatives and improve the overall performance of the application.

Q: How do I implement caching to store the results of previous searches?

A: To implement caching to store the results of previous searches, you need to use a caching library or framework that supports caching. This can help reduce the number of requests to the HDD or YTS and improve the overall performance of the application.

Conclusion

In this article, we answered some frequently asked questions (FAQs) related to handling missing movie cases. We covered topics such as the purpose of handling missing movie cases, implementing the logic for handling missing movie cases, and the benefits of handling missing movie cases. By handling missing movie cases correctly, we can provide a better user experience and improve the overall performance of the application.
