ROOST_METHOD_HASH=createProduct_60409495d0
ROOST_METHOD_SIG_HASH=createProduct_5b0158b3eb

Scenario 1: Testing creation of a product with valid data

Details:
TestName: createProductWithValidData()
Description: The test aims to check if a product is successfully created when supplied with valid data, conforming to the expected field requirements.

Execution:
Arrange: Create a mock product with all necessary details (name, description, price, etc.). Mock the product repository to return the product when save() is called.
Act: Call createProduct method with the mock product.
Assert: Using JUnit assertions to check if the returned product is not null and matches the mock product.

Validation:
Asserting here aims to verify that the method can successfully create a product with valid data as per the defined business logic. This scenario is significant as it validates the basic creation functionality of the product.

Scenario 2: Testing creation of a product with null data

Details:
TestName: createProductWithNullData()
Description: The test aims to check the scenario when a product creation is attempted with null data.

Execution:
Arrange: Mock the product repository to return null when save() is called with null.
Act: Call createProduct method with null.
Assert: Using JUnit assertions to check if the returned product is null.

Validation:
This assertion verifies that the method appropriately handles null data and does not create a product, meeting necessary validity checks. This scenario is significant as it validates the application's robustness in handling invalid input.

Scenario 3: Error Exception when Repository is unavailable

Details:
TestName: createProductWhenRepositoryUnavailable()
Description: The test aims to check the scenario when an error is expected due to unavailable product repository.

Execution:
Arrange: Mock the product repository to throw a RuntimeException when save() is called.
Act: Call createProduct method with a valid product.
Assert: Using JUnit assertions to check if a RuntimeException is thrown.

Validation:
Asserting here aims to verify that in case of underlying system unavailability (like Database), the method throws an exception as per the application's exception handling and recovery mechanism. This scenario is significant as it validates system stability under crucial circumstances.

Scenario 4: Creating a product that already exists in the repository

Details:
TestName: createProductThatAlreadyExists()
Description: The test aims to check the scenario when a product already present in the repository is being created again.

Execution:
Arrange: Mock the product and save it to the repository.
Act: Call createProduct method with the same product.
Assert: Using JUnit assertions to check if a DuplicateResourceException or an equivalent is thrown or handled.

Validation:
This assertion verifies that the code prevents duplication of products in the repository as per the business rules. This scenario is significant as it ensures the application's integrity of data.
