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.

DALL-E Prompt to Generate JavaScript Code
DALL-E, the image generation model developed by OpenAI, is not designed to produce executable JavaScript code. However, it can play a valuable complementary role in a JavaScript developer's workflow. DALL-E excels at creating visuals related to development: user interface mockups, architecture diagrams, data flow schemas, or illustrations to document your code. By crafting precise prompts, you can obtain visual representations of complex JavaScript concepts like closures, the event loop, or design patterns. These visuals then serve as references for implementing your code, creating attractive technical documentation, or designing educational materials. The approach is to use DALL-E as a rapid visual prototyping tool: generate a UI mockup, then translate it into JavaScript components. This method accelerates the design phase and reduces back-and-forth between designers and developers. In this guide, we offer optimized prompts to get the most out of DALL-E in your JavaScript development process, from UI prototyping to visual documentation of your code.
