PR Overview
This PR introduces a new IHashUtils interface and a HashUtilsService class to handle hashing operations, refactoring the existing hash computation to use the new interface while adding comprehensive unit tests.
- Introduces the IHashUtils interface and its implementation in HashUtilsService.
- Refactors the static HashUtils class to delegate hash computation to the new interface.
- Adds unit tests to validate both the service implementation and the static wrapper behavior.
Reviewed Changes
| File | Description |
|---|---|
| CodeLineCounter.Tests/HashUtilsMockTests.cs | Tests mocking of IHashUtils to ensure HashUtils correctly defers to the implementation. |
| CodeLineCounter.Tests/HashUtilsServiceTests.cs | Provides unit tests for the HashUtilsService behavior under different input conditions. |
| CodeLineCounter/Utils/HashUtilsService.cs | Implements the hashing algorithm using SHA256 and returns a hex string representation. |
| CodeLineCounter/AssemblyInfo.cs | Adds InternalsVisibleTo attribute for test accessibility. |
| CodeLineCounter/Utils/IHashUtils.cs | Declares the IHashUtils interface with a ComputeHash method signature. |
| CodeLineCounter.Tests/HashUtilsTests.cs | Confirms that the static HashUtils class initializes its Implementation and defers to it. |
| CodeLineCounter/Utils/HashUtils.cs | Refactors the static hash computation to utilize the IHashUtils implementation. |

PR Overview
This PR implements a new hashing utility by introducing an IHashUtils interface and a corresponding HashUtilsService class. It refactors the existing HashUtils static class to delegate computation to the new service and adds comprehensive unit tests to ensure functionality.
- Introduces IHashUtils and HashUtilsService for hashing operations.
- Refactors HashUtils static class to use dependency injection via an internal Implementation property.
- Adds new tests (including mock-based tests) to validate both the service and integration behaviors.
