The 8 steps of AI-driven development AI-Driven Development (AIDD) offers a modern spin on the traditional “red, green, refactor” cycle of Test-Driven Development (TDD). It incorporates AI to amplify the developer’s ability, resulting in a partnership between human expertise and machine intelligence. Unlike TDD, where developers script both unit tests and code, AIDD melds deep AI integration into the process. With AI in tow, developers can delegate specific tasks to their AI counterparts, ensuring a more efficient development cycle. Here’s a detailed overview of the AIDD steps: Step 1: Define the objective Envision the function’s objective from a high-level Input→Output perspective. Ponder on the function’s API: The number and nature of arguments, their necessity, and more. Step 2: Design the abstract type Utilize a robustly typed language (e.g., TypeScript, C#, Haskell) to manually craft the function’s input and output type or interface. Emphasize pure functions to minimize side effects. Remember, AI is always at your disposal if you need guidance. 4/15

5. Step 3: Develop mock functions Share the abstract type with the AI to generate a mock function. This function, devoid of actual implementation, mirrors a real function by mimicking its output. Step 4: Author test Instruct the AI to generate unit tests based on the function type and desired outcomes. Examine the generated tests. Refine or augment them as required. Alternatively, draft rudimentary tests and ask the AI to expand more assertively, diminishing the odds of accidental test success. Prioritize swift unit tests achieved by pure functions, dependency injection, mocking, and more. Step 5: Execute tests, anticipate failures Run the tests against the mock function. If tests don’t predominantly fail, revisit step 4 to bolster test comprehensiveness. Step 6: Craft the concrete implementation Here, AI plays a pivotal role. Feed it the types or interfaces, verbal descriptions, or unit tests. Let AI propose a concrete solution. Step 7: Run tests, foresee success Test the AI-proposed solution. In the event of failures, two routes are possible: Encourage AI to reattempt, offering error insights. Scrutinize the function, either rectifying it or creating a new one. Utilize AI’s suggestions if needed. Step 8: Optimization and refinement Post-test success: manually review the function to ensure its alignment with best software development practices. Refactor if needed. Should tests flounder during refactoring, loop back to AI collaboration as done in step 7. One crucial takeaway is the irreplaceability of human intuition and expertise, despite the potent AI support, evident primarily in steps like refining and optimizing code. Leveraging AI tools for software development: An example using ChatGPT AI-powered development involves using AI for software creation, with developers guiding the AI for the best results. We will delve into these specific techniques with an example of ChatGPT: Crafting foundational code and execution While ChatGPT excels at producing code fragments, it might not always draft a comprehensive solution without adequate direction and context. When dealing with a Spring Boot (Spring MVC) project, it’s essential to grasp the framework’s basics to use ChatGPT effectively. For example, if you aim to design a basic CRUD application to fetch book information from an Azure SQL database, you must furnish ChatGPT with relevant specifics. Initially, you can prompt ChatGPT to devise a controller, service, and repository for accessing and storing book information. Nevertheless, remember that you should be familiar with a Spring Boot project’s core structure and elements. ChatGPT could potentially overlook some aspects if the context isn’t rich enough. Therefore, clarify the elements you want ChatGPT to formulate when posing a query. Prompt: Can you show me the code samples of creating a controller, repository, and service retrieving book data from azure sql database. Of course! Below are basic examples of a controller, repository, and service for retrieving book data from an Azure SQL database within a Spring Boot (Spring MVC) context. This is a simplified representation and might require additional configurations and dependencies, such as adding Azure SDK and Spring Boot Data JPA to your pom.xml. Entity (Book.java) @Entity @Table(name = "books") public class Book { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String title; private String author; // ... getters and setters ... 5/15

6. } Repository (BookRepository.java) import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.stereotype.Repository; @Repository public interface BookRepository extends JpaRepository<Book, Long> { // Here you can define additional query methods if necessary } Service (BookService.java) import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; @Service public class BookService { @Autowired private BookRepository bookRepository; public List<Book> getAllBooks() { return bookRepository.findAll(); } // You can add other service methods like save, update, delete, etc. } Controller (BookController.java) import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import java.util.List; @RestController @RequestMapping("/api/books") public class BookController { @Autowired private BookService bookService; @GetMapping public List<Book> getAllBooks() { return bookService.getAllBooks(); } // You can add other endpoints for operations like POST, PUT, DELETE, etc. } Remember, for the Azure SQL database connection, you will need to provide the necessary configurations in application.properties (or application.yml), including the database URL, username, password, etc. Additionally, you will need to integrate the Azure SDK or related library to communicate directly with Azure services. Ensure you have set up the necessary dependencies in your Maven or Gradle configuration. This is a basic setup. Depending on your application requirements, there might be a need for more configurations, exception handling, validation, etc. Now if you want to generate also the configuration files, just ask ChatGPT the following: Prompt: Please provide the code required for the configuration files Absolutely. Setting up a Spring Boot application to connect with Azure SQL Database involves several steps. Here is a basic configuration for your application.properties to connect to an Azure SQL Database: application.properties # Spring Datasource Configuration spring.datasource.url=jdbc:sqlserver://your_server_name.database.windows.net:1433;databaseName=your_db_name;encrypt=true;trustServerCe spring.datasource.username=your_username spring.datasource.password=your_password spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver # Hibernate Configuration spring.jpa.show-sql=true spring.jpa.hibernate.ddl-auto=update 6/15

7. spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialectspring.jpa.properties.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect Ensure the following dependencies are included in your pom.xml: pom.xml (relevant dependencies) <!-- Spring Boot Starter Web for RESTful API --> org.springframework.boot spring-boot-starter-web <!-- Spring Boot Starter Data JPA for database access --> org.springframework.boot spring-boot-starter-data-jpa <!-- Microsoft SQL Server JDBC driver --> com.microsoft.sqlserver mssql-jdbc 8.4.1.jre8 <!-- Adjust based on the latest version or your Java version --> You might also want to add a configuration class (optional): DatabaseConfig.java import org.springframework.context.annotation.Configuration; import org.springframework.data.jpa.repository.config.EnableJpaRepositories; @Configuration @EnableJpaRepositories(basePackages = "com.yourpackage.repository") public class DatabaseConfig { // Here, you can add additional database configurations if necessary } Remember: Replace placeholders (your_server_name, your_db_name, your_username, your_password, etc.) with your actual Azure SQL database credentials. Ensure you have properly set up an Azure SQL Database and have necessary access to it. Keep your database credentials safe. Using environment variables or external configuration services like Azure Key Vault for storing credentials is recommended. Depending on your exact requirements and setup, you might need further configurations, especially when dealing with more advanced features or when considering production-ready settings. The subsequent action involves tailoring our methods based on our specific needs. Say we aim to dispatch an Azure Service Bus notification whenever a book gets added; we can seek guidance from ChatGPT. Consider posing this question as an illustration: Prompt: Please add the Azure Service Bus Message Queue to my solution and send a message every time a book is uploaded. Show me the code changes that need to be made. Sure, to integrate the Azure Service Bus into your solution and send a message every time a book is uploaded, follow these steps: Maven Dependencies: Add the required dependencies to your pom.xml: com.azure azure-messaging-servicebus 7.0.0 Configuration: Add Azure Service Bus connection string to your application.properties or application.yml file: azure.servicebus.connection-string=YOUR_CONNECTION_STRING Service Bus Configuration: Create a configuration class to set up the Service Bus client: @Configuration public class ServiceBusConfig { @Value("${azure.servicebus.connection-string}") private String connectionString; @Bean public ServiceBusSenderClient serviceBusSenderClient() { return new ServiceBusClientBuilder() .connectionString(connectionString) .sender() .queueName("your-queue-name") .buildClient(); } 7/15

8. } Service Changes: Inject ServiceBusSenderClient into your service and use it to send a message when a book is uploaded. @Service public class BookService { @Autowired private BookRepository bookRepository; @Autowired private ServiceBusSenderClient serviceBusSenderClient; public Book uploadBook(Book book) { Book savedBook = bookRepository.save(book); // Create a message to send to the queue ServiceBusMessage message = new ServiceBusMessage("A book with title " + book.getTitle() + " has been uploaded."); // Send the message to the Azure Service Bus serviceBusSenderClient.sendMessage(message); return savedBook; } } Controller changes: There aren’t any specific changes needed in the controller as long as you are calling the uploadBook method from the service when a book gets uploaded. Now, every time a book is uploaded, a message will be sent to the Azure Service Bus. Ensure that you have properly set up your Azure Service Bus on the Azure Portal and have the correct connection string in your application properties. With ChatGPT’s assistance, you can enhance your code quality. If you have crafted or adjusted your code, prompt ChatGPT to refine it for clarity or brevity. It’s worth noting that ChatGPT isn’t set to optimize code by default; you have to make a specific request. Ensure you offer ample details to ChatGPT for it to provide accurate suggestions. Lack of context might lead it astray. Error management, unit testing, and code annotations An essential enhancement to our code is incorporating error management. ChatGPT proves invaluable for such tasks. As an initial step, we can prompt it to weave error management into a particular function in our code. Suppose we possess a function designated for fetching a book. We can encourage ChatGPT to refine this function with error management provisions. Precision is crucial when directing ChatGPT for error management, as it might default to broad error responses. For clarity, we could instruct it to raise a “BookNotFound” exception when the book is unavailable. Prompt: Please add error handling for retrieving a specific book, throw a custom error “BookBotFound” if the book isn’t found, display code the code parts Certainly, let’s walk through the necessary adjustments for adding error handling to a book retrieval method. Let’s consider a simple Spring Boot RESTful service. Here is how you can handle errors: Custom exception Firstly, create a custom exception class BookBotFoundException. package com.example.demo.exceptions; public class BookBotFoundException extends RuntimeException { public BookBotFoundException(String message) { super(message); } } Controller Let’s assume a basic BookController that retrieves a book by its ‘id.’ package com.example.demo.controllers; import com.example.demo.exceptions.BookBotFoundException; import com.example.demo.models.Book; import com.example.demo.services.BookService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping("/books") 8/15

9. public class BookController { @Autowired private BookService bookService; @GetMapping("/{id}") public Book getBookById(@PathVariable Long id) { return bookService.findBookById(id).orElseThrow(() -> new BookBotFoundException("Book not found for id: " + id)); } } Service The BookService class would likely have a method like: package com.example.demo.services; import com.example.demo.models.Book; import com.example.demo.repositories.BookRepository; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.Optional; @Service public class BookService { @Autowired private BookRepository bookRepository; public Optional<Book> findBookById(Long id) { return bookRepository.findById(id); } } Exception Handling To handle the custom exception and send an appropriate response to the user, use @ExceptionHandler. package com.example.demo.controllers; import com.example.demo.exceptions.BookBotFoundException; import org.springframework.http.HttpStatus; import org.springframework.web.bind.annotation.ExceptionHandler; import org.springframework.web.bind.annotation.ResponseStatus; // ... rest of the controller ... @ExceptionHandler(BookBotFoundException.class) @ResponseStatus(HttpStatus.NOT_FOUND) public String handleBookNotFound(BookBotFoundException ex) { return ex.getMessage(); } With the above implementation, when a user tries to retrieve a book with a non-existent ID, the application will return a 404 NOT FOUND status with the message “Book not found for id: [id]”. Once error handling is integrated, it’s essential to validate our code through unit tests. We can craft these tests ourselves or seek assistance from ChatGPT to generate them. Nonetheless, it’s vital to ensure the comprehensive coverage of tests and fine-tune any that might be misaligned. While ChatGPT offers significant capabilities, it isn’t infallible. Thus, possessing a thorough grasp of the code is paramount to ensure we refine it appropriately. Prompt: Create unit tests retrieving a book, display the code. Certainly! Assuming you are using a Java-based Spring framework and JUnit for unit testing, here is an example of unit tests for a method that retrieves a book: import org.junit.jupiter.api.BeforeEach; import org.junit.jupiter.api.Test; import org.mockito.InjectMocks; import org.mockito.Mock; import org.mockito.MockitoAnnotations; import org.springframework.boot.test.context.SpringBootTest; import java.util.Optional; import static org.junit.jupiter.api.Assertions.*; import static org.mockito.Mockito.*; @SpringBootTest public class BookServiceTest { 9/15

10. @InjectMocks private BookService bookService; @Mock private BookRepository bookRepository; private Book testBook; @BeforeEach public void setup() { MockitoAnnotations.initMocks(this); testBook = new Book(); testBook.setId(1L); testBook.setTitle("Test Book"); testBook.setAuthor("John Doe"); } @Test public void testRetrieveBook_WithValidId_ReturnsBook() { when(bookRepository.findById(1L)).thenReturn(Optional.of(testBook)); Book result = bookService.getBookById(1L); assertNotNull(result); assertEquals(testBook, result); } @Test public void testRetrieveBook_WithInvalidId_ThrowsBookBotFound() { when(bookRepository.findById(2L)).thenReturn(Optional.empty()); Exception exception = assertThrows(BookBotFound.class, () -> { bookService.getBookById(2L); }); String expectedMessage = "Book not found with id: 2"; String actualMessage = exception.getMessage(); assertTrue(actualMessage.contains(expectedMessage)); } } Assumptions made: 1. BookService has a method getBookById(Long id) which retrieves a book by its ID. 2. BookRepository is an interface extending JpaRepository or any other suitable Spring Data repository interface. 3. BookBotFound is a custom exception you have defined to be thrown when the book isn’t found. This is a basic example and can be extended with more cases, configurations, or scenarios as required. Make sure to modify and adapt the code to fit into your application’s structure and requirements. Troubleshooting and error correction While ChatGPT is adept at rectifying straightforward code discrepancies and mending syntax errors, it might struggle with intricate challenges like memory leak detection or deep-seated logic flaws. In such scenarios, although ChatGPT can give guidance and backup, the final duty of ironing out the code issues remains with the developer. Prompt: Cannot convert s (variable of type string) to type dependency.Dependency The error “Cannot convert s (variable of type string) to type dependency.Dependency” indicates that there is an attempt to assign or convert a variable s of type string to an object or variable of type dependency.Dependency, which is not directly possible without a proper conversion method. To resolve this error, you have several options depending on the context: Define a conversion method: If it makes sense in the context of your application, define a method within dependency.Dependency class that accepts a string and converts it to a Dependency instance. public class Dependency { public static Dependency fromString(String s) { Dependency dep = new Dependency(); // Conversion logic here return dep; } } Then, you can use it as: 10/15

11. Dependency myDependency = Dependency.fromString(s); 1. Check the assignment: It is possible there is a mistake in the assignment logic. Make sure that you are not inadvertently trying to assign a string value to a variable or parameter that expects a Dependency type. 2. Use constructors: If your Dependency class has a constructor that accepts a string, you can use that for conversion. public class Dependency { public Dependency(String s) { // Initialize Dependency object using string s } } And you can create an instance using: Dependency myDependency = new Dependency(s); Re-evaluate your design: It’s essential to think about why you are trying to convert a string to a Dependency object. Is it necessary? Does it make sense in the context of your application’s design? Sometimes, rethinking the design can provide clarity and simplify the implementation. Remember that the provided solutions are generic, and you might need to adjust them according to your specific context and application needs. Enhancing code efficiency ChatGPT can guide you in refining your code by offering solutions that minimize redundancy, enhance clarity, and boost code reusability. However, it’s crucial to give precise instructions and review the suggestions from ChatGPT to ensure they align with your objectives. While refining code is beneficial, overdoing it can sometimes lead to unexpected issues. Therefore, it’s recommended to implement changes that genuinely add value. Always remember that unnecessary code enhancements can consume valuable time and resources. Data conversion ChatGPT has a robust feature set for converting textual input into different structures. For instance, it can easily convert a text snippet into its JSON counterpart. Depending on your preference, the resultant JSON can be either basic or detailed. Beyond JSON, ChatGPT can adapt text into several other formats, such as YAML, HTML, XML, and CSV, ensuring the final structure aligns with your precise needs. Implementing AI-driven development: Key considerations AI-driven development integrates AI tools and techniques into the software development lifecycle to enhance productivity, reduce manual effort, and introduce new capabilities to software products. This approach doesn’t just transform the traditional methods but reshapes the role of developers, leveraging the power of AI to aid them.
