Fixes #9

Description:

Here is how I approached the problem.

Problem Summary:

The current issue is a request to add more unit tests to the existing codebase to increase the test coverage.
The dal module, which is part of the Order Management System (OMS) application, is responsible for data access and persistence.
The module uses Spring Data JPA for data access abstraction and integrates with Hibernate EntityManager for ORM capabilities.
It connects to a MySQL database using the MySQL Connector/J and depends on the oms-model module for data models.
The goal is to ensure that the dal module has sufficient unit tests to cover various scenarios and edge cases.
No specific error messages or incorrect behavior have been reported, but the lack of test coverage is a concern.

Solution Plan:

I reviewed multiple solutions and picked the following solution.

The best solution is to create unit tests for each repository interface using JUnit and Mockito. This approach is simple and straightforward, ensuring that each repository's functionality is tested without modifying the existing codebase.

Here is why I selected the above solution:

This solution adheres to the principles of YAGNI and KISS by focusing only on the necessary changes. It minimizes the surface area of the change by adding new test files without altering the existing repository interfaces. This ensures that the core functionality remains untouched while providing the required test coverage.

Implementation Plan:

Create a new test class for OrderLineRepository in src/test/java/com/oms/repository/OrderLineRepositoryTest.java
Create a new test class for SalesOrderRepository in src/test/java/com/oms/repository/SalesOrderRepositoryTest.java
Create a new test class for InventoryRepository in src/test/java/com/oms/repository/InventoryRepositoryTest.java
Create a new test class for ProductRepository in src/test/java/com/oms/repository/ProductRepositoryTest.java
Create a new test class for ShippingRepository in src/test/java/com/oms/repository/ShippingRepositoryTest.java
In each test class, use JUnit and Mockito to write unit tests for the CRUD operations and any custom query methods defined in the respective repository interfaces
Ensure that each test class is annotated with @SpringBootTest and @RunWith(SpringRunner.class) to enable Spring context loading and integration with JUnit
Mock the dependencies and use @MockBean to inject them into the test context
Write test methods to verify the behavior of each repository method, including edge cases and expected exceptions

Fixes #9

Description:

Here is how I approached the problem.

Problem Summary:

The current codebase of the 'service' module in the Order Management System (OMS) application lacks sufficient unit tests.
The request is to add more unit tests to increase the test coverage of the existing code.
The 'service' module integrates with other OMS modules such as 'oms-integrations', 'oms-dal', 'oms-model', and 'oms-gemfire-support'.
The module utilizes Spring Framework's 'spring-context' for dependency injection and application context management.
Lombok is used to reduce boilerplate code in Java classes.
The goal is to ensure that the core business logic and service layer are thoroughly tested.

Solution Plan:

I reviewed multiple solutions and picked the following solution.

The best solution is to create straightforward unit tests for each service class listed. Each test will focus on the core functionalities of the service, ensuring that the methods behave as expected. This approach adheres to the principles of YAGNI and KISS by only implementing the necessary tests without overcomplicating the solution.

Here is why I selected the above solution:

This solution is the best because it directly addresses the task requirements without introducing unnecessary complexity. It ensures that each service's core functionalities are tested, which is crucial for maintaining the integrity of the application. By focusing on the essential tests, we minimize the surface area of change and adhere to best practices.

Implementation Plan:

Create a test class for ShippingService in src/test/java/com/oms/service/ShippingServiceTest.java.
Create a test class for DinersPaymentService in src/test/java/com/oms/service/DinersPaymentServiceTest.java.
Create a test class for InventoryService in src/test/java/com/oms/service/InventoryServiceTest.java.
Create a test class for OrderService in src/test/java/com/oms/service/OrderServiceTest.java.
Create a test class for EmailService in src/test/java/com/oms/service/EmailServiceTest.java.
Create a test class for StoreSearchService in src/test/java/com/oms/service/StoreSearchServiceTest.java.
Create a test class for AddressValidationService in src/test/java/com/oms/service/AddressValidationServiceTest.java.
Create a test class for ModifyFulfillmentService in src/test/java/com/oms/service/ModifyFulfillmentServiceTest.java.
Create a test class for PaymentService in src/test/java/com/oms/service/PaymentServiceTest.java.
Create a test class for ProductService in src/test/java/com/oms/service/ProductServiceTest.java.
In each test class, write unit tests for the core methods of the corresponding service, such as fetch, create, modify, and validate methods.
Use Mockito to mock dependencies and focus on testing the business logic of each service.
Ensure that each test class is annotated with @SpringBootTest or @ExtendWith(SpringExtension.class) as needed to integrate with the Spring context.

Description:

Here is how I approached the problem.

Problem Summary:

The current issue is the need to increase the test coverage of the existing code in the app module of the Order Management System (OMS) application.
The module is a Spring Web MVC application packaged as a WAR file and uses Java 8.
It includes dependencies such as Spring Data JPA, Spring Context, Spring WebMVC, Spring Core, Spring ORM, Spring Web, Hibernate EntityManager, MySQL Connector, Lombok, Jackson Core, Jackson Databind, and Spring Data Geode.
The module also has test dependencies including Spring Test, JUnit, and Mockito.
The module depends on other OMS modules such as oms-dal, oms-gemfire-support, oms-integrations, and oms-service.
The goal is to add more unit tests to the existing code to ensure better test coverage and reliability.
The tests should be placed in the src/test/java directory as per the project structure.

Solution Plan:

I reviewed multiple solutions and picked the following solution.

The simplest solution is to add unit tests for each of the specified controllers and the configuration class. This involves creating test classes in the src/test/java directory, using JUnit and Mockito to mock dependencies and verify the behavior of each method in the controllers and configuration class.

Here is why I selected the above solution:

This solution is straightforward and adheres to the principles of YAGNI and KISS. It focuses on adding the necessary unit tests without making any changes to the existing codebase, thus reducing the surface area of change.
