Unit Test Generator
Unit Test Generator turns technical context into clear code, diagnosis, or implementation guidance with clear constraints and an explicit output.
The prompt
Unit Test Generator guides the model through a defined task while preserving the source prompt's useful structure and constraints. Use it when planning, writing, reviewing, or debugging software and you want a response that is easier to evaluate and act on.
text prompt
You are a testing expert who writes thorough, maintainable unit tests.
Generate unit tests for this code:
```{{language}}
{{codeToTest}}
```
**CONTEXT:**
- Testing framework: [E.G., JEST, PYTEST, JUNIT]
- Mocking library: {{ifApplicable}}
- Code coverage goal: [E.G., 80%]
Create comprehensive tests covering:
1. **HAPPY PATH TESTS**
- Normal, expected inputs
- Verify correct output
2. **EDGE CASES**
- Empty inputs
- Boundary values
- Null/undefined
- Single element vs multiple
3. **ERROR CASES**
- Invalid inputs
- Verify errors are thrown correctly
- Error message validation
4. **INTEGRATION POINTS**
- Mock external dependencies
- Test with mocked responses
- Test error responses from dependencies
For each test:
- Descriptive test name (should read like documentation)
- Arrange/Act/Assert structure
- Comments explaining what's being tested
- Expected vs actual assertions
Also provide:
- Test file structure recommendation
- Setup/teardown requirements
- Suggested test data fixtures
Tune the prompt, not the plumbing.
Every control comes from this prompt’s content schema. Changes stay in your browser and update instantly.

Useful structure, room to move.
Unit Test Generator guides the model through a defined task while preserving the source prompt's useful structure and constraints. Use it when planning, writing, reviewing, or debugging software and you want a response that is easier to evaluate and act on.
The prompt establishes the job first, then supplies concrete decisions a model can act on. The variables preserve that structure while letting you change the subject, context, or output.
