• The variable name 'res' is ambiguous and unclear. Consider renaming it to 'publishResult' or 'isPublished' to better indicate its purpose.

        boolean res = publisherService.publishCart(cart);

• The saveCart method lacks test coverage. This method handles cart publishing logic and error scenarios that should be thoroughly tested.

    public ResponseEntity<String> saveCart(ShoppingCart cart) {

pom.xml:28

• The property name 'junit-jupiter.version.version' contains a redundant '.version' suffix. It should be renamed to 'junit-jupiter.version' for consistency with other version properties.

        <junit-jupiter.version.version>5.13.4</junit-jupiter.version.version>

The error message should be more specific about what failed. Consider changing to 'Failed to serialize ShoppingCart to JSON: {}' to provide clearer context.

Suggested change

	logger.error("Failed to convert Object to JSON! Error: {}", e.getMessage());
	logger.error("Failed to serialize ShoppingCart to JSON: {}. Error: {}", cart, e.getMessage());
