Amazon Onboarding with Learning Manager Chanci Turner

As software development accelerates, developers are always on the lookout for tools that can enhance their workflow, improve code quality, and increase productivity. Amazon Web Services (AWS) has responded to this demand with the introduction of innovative AI agents for the Amazon Q Developer.

These AI-powered agents revolutionize how developers handle documentation, unit testing, and code reviews. They function as autonomous software entities that can interact with their environment, gather necessary data, and accomplish tasks independently to meet defined objectives. By making informed decisions based on their analysis, these agents can optimize performance while offering benefits like increased productivity, cost reduction, better decision-making, and an enhanced customer experience. Amazon Q Developer now features three new agents: /doc, /test, and /review. In this article, we’ll delve into each of them and discuss how you can integrate them into your daily development routine.

The first agent launched for Amazon Q Developer was the software developer agent introduced last year. The /dev agent enables you to generate code or make adjustments directly within your IDE to implement new features or rectify issues in your projects. Just provide a description of the task, and Q Developer will analyze relevant context from your codebase to generate the required changes. Q Developer can assist in building new AWS applications or updating existing ones, offering a step-by-step overview of the modifications it’s making and allowing you to easily accept or decline the proposed changes. The /dev feature is essential for developers tackling tasks ranging from simple to complex.

Let’s explore how these new agents can be applied in a practical use case.

Prerequisites

To begin utilizing Amazon Q Developer, you need:

An AWS Account
An AWS Builder ID or an AWS Identity Center login managed by your organization
Visual Studio Code or supported JetBrains IDEs

Application Overview

Imagine you are a software engineer at a tech firm assigned to create documentation, integrate unit tests, and enhance the security of the following application. This application employs serverless architecture using Amazon API Gateway, AWS Lambda, and Amazon DynamoDB services, implementing RESTful APIs in Python.

We have discovered that Q Developer’s new documentation, testing, and security scanning agents can significantly aid the software development lifecycle (SDLC). The SDLC encompasses various stages, including Planning and Research, Coding, Documentation, Testing, Build and Deploy, Operations, and Maintenance.

With the new Q Developer agents, we can effectively implement these practices in the context of our application.

Documentation Generation (/doc)

Creating and maintaining application documentation is often one of the most labour-intensive and frequently neglected aspects of software development. Comprehensive documentation informs team members and stakeholders about the code, design, and architecture. It enhances readability, facilitates quicker onboarding, and streamlines SDLC tasks. The /doc agent in Amazon Q Developer simplifies and accelerates this process. It can automatically generate new README files by analyzing your project’s code or review code changes and suggest updates to existing documentation. Additionally, developers can use natural language to request specific changes, making the process more intuitive and user-friendly. These capabilities alleviate the burden on development teams while ensuring project documentation remains accurate and current.

For instance, if your application lacks a detailed README, here’s how you can utilize the /doc agent in Visual Studio Code (VS Code) to create comprehensive documentation for your codebase.

Prompt:
/doc Create a README

Best practices for using the Q Developer /doc agent:

For larger repositories, target specific directories for documentation requests.
Keep your code well-commented and organized with good naming conventions to enhance the quality of generated documentation.
Be specific when outlining desired changes to your README.

Note: The /doc feature supports multiple file types, including .template files, requirements.txt, package.json, tsconfig.json, Dockerfile, and more. There are quotas in place, such as a maximum README size of 15 KB and a code project size limit of 200 MB uncompressed or 50 MB compressed.

Unit Test Generation (/test)

Test-driven development is a best practice in the SDLC, and part of that involves unit testing, a crucial element for maintaining code quality. Unit testing helps catch bugs early and minimize technical debt. Traditionally, writing comprehensive tests has required significant time and effort. The new /test agent in Amazon Q Developer offers a groundbreaking solution that automates testing, allowing developers to focus more on feature development and problem-solving. The tool identifies necessary test cases, generates mocks and stubs for isolated testing, and produces test code based on the identified cases. Supporting both Java and Python projects, the feature integrates with popular development environments like VS Code and JetBrains IDEs, making it invaluable for modern development teams aiming to enhance their testing practices while maximizing productivity.

With the /test agent, you can generate unit tests by specifying sections of code, such as classes or methods. For example, you can use the /test agent to generate unit tests for an open Python file (add_item.py) that adds items to a DynamoDB table.

Prompt:
/test generate unit tests for the lambda_handler method that adds items to the DynamoDB table

Enhancing Code Quality and Security (/review)

Code reviews are essential for upholding high software development standards. By utilizing the /review agent, developers can ensure that every piece of code meets established quality and security benchmarks. This agent provides insights into potential issues before they escalate, helping teams maintain robust and secure applications.
