Sweep: Prepare the NoteService class for unit testing

[jreed-Aces]

Refactor the NoteService class and abstract the File calls so that file writing/reading can be mocked for future unit tests.

Step 2: 🧐 Snippet Analysis

From looking through the relevant snippets, I decided to make the following modifications:

File Path	Proposed Changes
Services/IFileService.cs	Create Services/IFileService.cs with contents: • Define an interface IFileService with three methods: bool Exists(string path), string ReadAllText(string path), and void WriteAllText(string path, string contents).
Services/FileService.cs	Create Services/FileService.cs with contents: • Create a class FileService that implements the IFileService interface. • Implement the Exists method to use File.Exists. • Implement the ReadAllText method to use File.ReadAllText. • Implement the WriteAllText method to use File.WriteAllText.
Services/NoteService.cs	Modify Services/NoteService.cs with contents: • Add a private readonly field of type IFileService. • Modify the constructor to take an IFileService parameter and assign it to the field. • Replace all direct file operations with calls to the IFileService methods.
Program.cs	Modify Program.cs with contents: • Add a line to the service setup to add the FileService as a singleton: services.AddSingleton<IFileService, FileService>().

Step 3: 📝 Planning

I have created a plan for writing the pull request. I am now working my plan and coding the required changes to address this issue. Here is the planned pull request:

Refactor NoteService for Unit Testing sweep/refactor-note-service

Description

This PR refactors the NoteService class in order to make it more testable. The current implementation directly interacts with the file system, which makes it difficult to unit test. To address this, the following changes were made:

• Created an interface, IFileService, to abstract file operations.
• Implemented the IFileService interface in a class, FileService, which contains the actual file operations.
• Modified the NoteService class to use the IFileService for file operations.
• Modified the Program class to include the new FileService in the dependency injection setup.

Summary of Changes

• Added IFileService interface with methods for checking file existence, reading file contents, and writing file contents.
• Implemented IFileService in FileService class with actual file operations.
• Modified NoteService to use IFileService for file operations.
• Modified Program class to include FileService in dependency injection setup.

Step 5: 🔁 Code Review

Here are my self-reviews of my changes at sweep/refactor-note-service.

Here is the 1st review

No changes required. The code changes are well implemented and there are no syntax errors or unimplemented sections. Good job!

I finished incorporating these changes.
