Design Checklist is an AI-powered Test Case Generation tool that automatically analyzes project requirements and generates test scenarios and cases tailored to the development context. This tool enhances test quality, reduces human effort, and ensures alignment with business expectations.

This blog introduces how Design Checklist works, its features, and how it can improve the quality assurance process in software development.

What is Design Checklist

Design Checklist is a test design automation tool powered by Gemini 2.5 Pro LLM. It assists QA teams and project managers in transforming business requirements into structured test cases. With minimal manual input, users can generate viewpoint-based, scenario-based, high-level, or low-level test cases that align with the project scope.

Design Checklist simplifies test preparation, increases traceability, and supports standardized test quality across teams.

How Design Checklist Works

The power of Design Checklist lies in its intelligent, multi-stage process, designed to bridge the gap between abstract project requirements and concrete, actionable test cases. It begins with comprehensive data input and culminates in precise, tailored test case generation.

1. Intelligent Input Analysis

The journey starts when a project manager or lead uploads the project requirements. These could be in various formats, such as user stories, functional specifications, or even informal documentation. This initial input forms the foundational understanding for the AI.

Crucially, users also have the option to upload a company master checklist. This is a powerful feature that ensures standardization and adherence to internal best practices. This master checklist can contain common testing scenarios, regulatory requirements, or domain-specific considerations that your organization consistently applies.

Both the project requirements and the optional master checklist are then fed directly into the Gemini 2.5 Pro LLM engine. Gemini’s advanced natural language understanding capabilities allow it to parse, interpret, and cross-reference these inputs, building a holistic understanding of the project’s scope, objectives, and specific nuances. It identifies key entities, relationships, and potential areas for testing, essentially digesting the entire business context before any test cases are even considered.

2. Contextual Processing and Preparation

Once the inputs are absorbed, Gemini doesn’t just parrot back information. It performs a deep contextual analysis. This involves:

Identifying core functionalities: Breaking down complex requirements into individual, testable features.
Understanding user flows: Mapping out potential interactions and sequences within the system.
Recognizing edge cases and exceptions: Anticipating scenarios that might deviate from the main path or lead to errors.
Integrating master checklist standards: Ensuring that all generated test cases align with the predefined quality and compliance standards of your organization.

This analytical phase prepares the LLM to generate truly relevant and effective test cases, ensuring they are not just syntactically correct but semantically aligned with your project’s goals.

3. Granular Test Case Generation Options

This is where the user gains significant control. After the initial analysis, the system presents the user with a crucial choice: the desired test case generation level. This flexibility allows teams to generate test cases appropriate for different stages of the development lifecycle or varying depths of testing. The available options include:

Viewpoint Level: Ideal for early-stage planning and stakeholder discussions. These test cases focus on broad perspectives, such as user roles (e.g., “As an admin, I can manage user accounts”) or system functionalities from a high-level architectural view.
Scenario Level: More detailed than viewpoint, these define specific sequences of actions and expected outcomes, often following the “Given-When-Then” format. They are excellent for illustrating how a user or system interacts with a particular feature (e.g., “Given a user is logged in, when they click ‘Add to Cart’, then the item is added to their shopping cart”).
High Level: These provide a comprehensive overview of testing areas without delving into minute steps. They define what needs to be tested but not necessarily every single click or input. This level is perfect for creating test suites for major features or modules.
Low Level: These are the most granular and detailed test cases. They specify exact steps, input data, expected results, and pre-conditions, often used directly by QA engineers for execution. This level ensures thorough coverage and leaves little room for ambiguity during testing.

4. Output and Actionable Reports

Based on the user’s selection, the Design Checklist system leverages Gemini’s capabilities to intelligently generate the appropriate test cases. These aren’t just raw text; they are structured, coherent, and directly traceable back to the initial project requirements and master checklist.

Finally, these generated test cases are compiled into a detailed report. This report is more than just a list; it’s an organized, actionable document that can be directly utilized by development and QA teams. It streamlines the test preparation phase, significantly reducing manual effort and potential for human error. The output is ready for immediate review, integration into test management systems, or direct execution, accelerating the entire software development lifecycle.
