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 normal cases, edge cases, and error scenarios. Automated unit test generation allows developers to save considerable time while improving code coverage. A good prompt must specify the programming language, the desired test framework, the expected behavior of the function under test, and the specific constraints of the project. This systematic approach ensures maintainable, readable tests that conform to industry best practices. Whether you are working on a REST API, a utility library, or a complex application, the prompts presented in this guide will help you produce professional-quality unit tests in seconds.

The prompt

Sora

Generate a complete unit test suite for the following function: [paste your function here]. Use the framework [Jest/PyTest/JUnit/other] with language [JavaScript/Python/Java/other]. Include the following test categories: 1) Normal 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 it works

This prompt is effective because it structures the request according to the three pillars of testing: normal cases, edge cases, and error cases, ensuring exhaustive 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.

Expected result

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, edge values, and error scenarios of your function.

Variants by level

FAQ

How to adapt the prompt if my function has external dependencies like a database?

Specify in your prompt the dependencies to mock by listing them explicitly. For example, add: "The function uses a DatabaseService with methods findById() and save(). 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 test framework should I specify in the prompt to get the best results?

Always specify the exact framework you use 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 yet, PyTest and Jest are the best documented frameworks and usually produce the most complete results. Also mention complementary libraries like @testing-library for React or unittest.mock for Python.

How to verify that 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 are not covered, rerun the prompt specifying: "Add tests to cover the following branches: [describe missing paths]." Also manually check that assertions test behavior and not implementation to avoid brittle tests.
