Introduction

In today's digital age, searching for movies on a Hard Disk Drive (HDD) is a common task. However, implementing a robust search logic can be a challenging task, especially when dealing with multiple file formats and case-insensitive searches. In this article, we will delve into the implementation of HDD search logic, covering the acceptance criteria, checklist, and providing a step-by-step guide on how to achieve this.

Acceptance Criteria

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

Given

A movie title is provided.

When

The movie exists in the HDD.

Then

Return the file path(s) of the movie.

Checklist

To ensure that our HDD search logic meets the requirements, we need to complete the following tasks:

Make the search case-insensitive

Convert the movie title to lowercase or uppercase before searching.
Use a case-insensitive file system or database.

Handle multiple matches

Return all file paths that match the movie title, regardless of file format.
Provide an option to filter results by file format.

Write unit tests for the HDD search logic

Test the search logic with different movie titles and file formats.
Verify that the search logic returns the correct file paths.

Implementation

To implement the HDD search logic, we will use a combination of programming languages and libraries. We will use Python as our primary language and the os and glob libraries to interact with the file system.

Step 1: Define the Search Function

import os
import glob

def search_movie(movie_title):
    # Convert the movie title to lowercase
    movie_title = movie_title.lower()

    # Get a list of all files in the HDD
    files = glob.glob('/path/to/hdd/*')

    # Initialize an empty list to store the file paths
    file_paths = []

    # Iterate over the files and check if the movie title is in the file name
    for file in files:
        if movie_title in file.lower():
            file_paths.append(file)

    # Return the list of file paths
    return file_paths

Step 2: Make the Search Case-insensitive

To make the search case-insensitive, we can convert the movie title to lowercase before searching. We can also use a case-insensitive file system or database.

def search_movie(movie_title):
    # Convert the movie title to lowercase
    movie_title = movie_title.lower()

    # Get a list of all files in the HDD
    files = glob.glob('/path/to/hdd/*')

    # Initialize an empty list to store the file paths
    file_paths = []

    # Iterate over the files and check if the movie title is in the file name
    for file in files:
        if movie_title in file.lower():
            file_paths.append(file)

    # Return the list of file paths
    return file_paths

Step 3: Handle Multiple Matches

To handle multiple matches, we can return all file paths that match the movie title, regardless of file format. We can also provide an option to filter results by file format.

def search_movie(movie_title, file_format=None):
    # Convert the movie title to lowercase
    movie_title = movie_title.lower()

    # Get a list of all files in the HDD
    files = glob.glob('/path/to/hdd/*')

    # Initialize an empty list to store the file paths
    file_paths = []

    # Iterate over the files and check if the movie title is in the file name
    for file in files:
        if movie_title in file.lower():
            if file_format is None or file.endswith(file_format):
                file_paths.append(file)

    # Return the list of file paths
    return file_paths

Step 4: Write Unit Tests

To write unit tests for the HDD search logic, we can use a testing framework such as unittest. We can test the search logic with different movie titles and file formats.

import unittest
from hdd_search import search_movie

class TestHDDSearch(unittest.TestCase):
    def test_search_movie(self):
        movie_title = 'The Shawshank Redemption'
        file_paths = search_movie(movie_title)
        self.assertGreater(len(file_paths), 0)

    def test_search_movie_case_insensitive(self):
        movie_title = 'the Shawshank redemption'
        file_paths = search_movie(movie_title)
        self.assertGreater(len(file_paths), 0)

    def test_search_movie_multiple_matches(self):
        movie_title = 'The Shawshank Redemption'
        file_format = '.mp4'
        file_paths = search_movie(movie_title, file_format)
        self.assertGreater(len(file_paths), 0)

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