Sora Prompt for Generating Unit Tests
Sora, developed by OpenAI, is primarily known as a video generation model, but its AI ecosystem can be leveraged for software development tasks, including generating unit tests. By crafting precise and structured prompts, you can harness Sora's contextual understanding capabilities to produce robust test suites covering nominal cases, edge cases and error scenarios. Automated unit test generation saves developers significant time while improving code coverage. A good prompt must specify the programming language, desired testing framework, expected behavior of the function to be tested, and project-specific constraints. This systematic approach ensures maintainable, readable tests that follow industry best practices. Whether you are working on a REST API, utility library or complex application, the prompts presented in this guide will help you produce professional-quality unit tests in seconds.
Paste in your AI
Paste this prompt in ChatGPT, Claude or Gemini and customize the variables in brackets.
Generate a complete unit test suite for the following function: [PASTE_YOUR_FUNCTION_HERE]. Use the [Jest/PyTest/JUnit/OTHER] framework with [JavaScript/Python/Java/OTHER] language. Include the following test categories: 1) Nominal case tests with typical valid inputs, 2) Edge case tests (null values, empty strings, negative numbers, empty arrays, maximum values), 3) Error case tests with verification of thrown exceptions, 4) Performance tests if applicable. Each test must follow the AAA pattern (Arrange, Act, Assert) with descriptive names in English explaining the tested behavior. Add comments explaining the logic of each test group. Ensure tests are independent of each other and have no side effects. Use mocks for external dependencies.

Why this prompt works
This prompt is effective because it structures the request around the three pillars of testing: nominal cases, edge cases, and error cases, ensuring comprehensive coverage. The explicit mention of the AAA pattern and test independence guides the AI toward recognized professional practices. Finally, specifying the framework and language eliminates any ambiguity in the output format.
Use Cases
Variants
Expected Output
You will obtain a complete unit test suite organized by category, with descriptive test names in English and precise assertions. Each test will follow the Arrange-Act-Assert pattern, with mocks for external dependencies and explanatory comments. Coverage will include main paths, boundary values, and error scenarios of your function.
Frequently Asked Questions
How do I adapt my prompt if my function has external dependencies like a database?
Specify the dependencies to be mocked in your prompt by listing them explicitly. For example, add: "The function uses a DatabaseService with findById() and save() methods. Create mocks for these dependencies with realistic return values." The more precise you are about the dependency interfaces, the more directly usable the generated mocks will be in your code.
Which testing framework should I specify in the prompt for the best results?
Always specify the exact framework you are using in your project: Jest or Vitest for JavaScript/TypeScript, PyTest for Python, JUnit 5 for Java, or NUnit for C#. If you haven't chosen one yet, PyTest and Jest are the best-documented frameworks and generally produce the most comprehensive results. Also mention complementary libraries like @testing-library for React or unittest.mock for Python.
How can I check if the generated tests cover enough cases?
After generating your tests, run them with a code coverage tool (Istanbul/nyc for JavaScript, coverage.py for Python, JaCoCo for Java). Aim for at least 80% branch coverage. If some paths aren't covered, re-run the prompt specifying: "Add tests to cover the following branches: [describe the missing paths]." Also manually verify that assertions test behavior and not implementation to avoid brittle tests.

Pour des tests plus exploitables, ajoutez dans le prompt des exemples concrets (entrée → sortie attendue). Précisez aussi les dépendances à mocker, la version du framework et, si besoin, un seuil de performance. Le modèle générera ainsi des assertions réalistes au lieu de deviner le comportement.

Sora Prompt for Creating E2E Tests
End-to-end (E2E) tests are essential for ensuring application reliability, but writing them remains time-consuming and repetitive. Sora, thanks to its advanced generation capabilities, makes it possible to automate the creation of complete E2E test scenarios in seconds. By formulating a precise prompt describing user journeys, expected interactions, and validation criteria, you obtain structured test suites covering nominal cases as well as edge cases. The prompt engineering approach applied to Sora transforms how QA and development teams approach test coverage. Instead of starting from a blank page, you describe the expected behavior of your application in natural language, and Sora generates the corresponding test code with appropriate assertions. This method significantly reduces the time needed to set up an E2E suite while maintaining a professional quality level. Whether you use Playwright, Cypress, or Selenium, the prompts presented here adapt to your technical stack and the complexity of your application.

GitHub Copilot Prompt for Creating a REST API
GitHub Copilot has become an essential assistant for developers looking to accelerate the creation of REST APIs. Thanks to its direct integration into the code editor, it understands the context of your project and generates structured code in real time. Whether you work with Node.js and Express, Python and FastAPI, or Java and Spring Boot, Copilot adapts to your tech stack to produce endpoints conforming to REST conventions. The main challenge lies in formulating the prompt: a well-structured prompt yields a complete API with data validation, error handling, authentication, and documentation. A vague prompt, on the other hand, will produce generic code requiring many adjustments. In this guide, we offer an optimized prompt that fully leverages GitHub Copilot's capabilities to generate a professional, testable, production-ready REST API. You will also discover variants adapted to your experience level as well as practical tips to get the most out of this tool on a daily basis.
