Pull Request Overview

This pull request introduces a new test case file and modifies the .gitignore file. The changes are aimed at improving the test coverage for the Comment class and ensuring that unnecessary files are not tracked by Git.

File: .gitignore (modified)

• Change Summary:

  • Added the line src/main/java/com/scalesec/.DS_Store to the .gitignore file.

• Purpose:

  • The addition of .DS_Store to the .gitignore file is intended to prevent macOS system files from being tracked in the repository. .DS_Store files are automatically created by macOS to store custom attributes of a folder, such as the position of icons or the choice of a background image.

File: src/test/java/com/scalesec/vulnado/Comment_tests.java (added)

• Change Summary:

  • A new test class CommentTest has been added with multiple test cases to validate the functionality of the Comment class.

• Test Cases Added:

  1. create_ShouldReturnComment_WhenCommitSucceeds:
     • Tests that a comment is successfully created when the database commit is successful.
  2. create_ShouldThrowBadRequest_WhenCommitFails:
     • Tests that a BadRequest exception is thrown when the database commit fails.
  3. fetchAll_ShouldReturnListOfComments:
     • Tests that fetching all comments returns a list of comments.
  4. delete_ShouldReturnTrue_WhenCommentDeleted:
     • Tests that deleting a comment returns true when the operation is successful.
  5. delete_ShouldReturnFalse_WhenCommentNotDeleted:
     • Tests that deleting a comment returns false when the operation fails.

• Implementation Details:

  • Utilizes Mockito to mock database connections and operations.
  • Uses JUnit assertions to validate the expected outcomes of each test case.
  • Mocks Connection, PreparedStatement, Statement, and ResultSet to simulate database interactions.

Recommendations

1. Code Duplication:

   • The test class contains duplicate methods and test cases. It is recommended to refactor the code to remove redundancy. For instance, the methods mockConnection and createMockConnection perform the same function and can be consolidated.

2. Exception Handling:

   • There is an inconsistency in the exception handling for the create method. One test expects a BadRequest exception, while another expects a ServerError. Ensure that the Comment.create method has consistent exception handling and update the tests accordingly.

3. Security Considerations:

   • Ensure that the SQL queries used in the Comment class are protected against SQL injection. Although this is not directly visible in the test cases, it is crucial to validate the implementation of the Comment class for security vulnerabilities.

4. Test Coverage:

   • Consider adding more test cases to cover edge cases, such as null or empty inputs for the Comment.create method, to ensure robustness.

By addressing these recommendations, the code quality and security can be further enhanced.
