# Windsurf Test Generation

## Overview

This skill enables AI-powered test generation for any codebase using Windsurf's Cascade. It analyzes function signatures, identifies edge cases, creates meaningful assertions, and generates mock data. Supports unit tests, integration tests, and component tests across multiple frameworks including Jest, Vitest, Mocha, pytest, and testing-library.

## Prerequisites

- Windsurf IDE with Cascade enabled
- Testing framework installed (Jest, Vitest, pytest, etc.)
- Project with testable code (functions, classes, components)
- Code coverage tool configured (optional but recommended)
- Understanding of testing patterns and best practices

## Instructions

1. **Configure Testing Framework**
2. **Select Target Code**
3. **Generate Tests with Cascade**
4. **Add Custom Scenarios**
5. **Integrate into Workflow**


See `{baseDir}/references/implementation.md` for detailed implementation guide.

## Output

- Test files with comprehensive coverage
- Mock data and fixture files
- Coverage report with metrics
- Test pattern documentation for team

## Error Handling

See `{baseDir}/references/errors.md` for comprehensive error handling.

## Examples

See `{baseDir}/references/examples.md` for detailed examples.

Overview

This skill enables AI-powered test generation for any codebase using Windsurf's Cascade. It produces comprehensive unit, integration, and component test suites tailored to your project's language and test framework. Use it to accelerate test coverage, surface edge cases, and generate fixtures and mock data automatically.

How this skill works

The skill analyzes code structure and function signatures to identify input shapes, side effects, and likely failure modes. It generates test cases with meaningful assertions, mocks, and fixtures, and emits test files for frameworks like Jest, Vitest, Mocha, and pytest. It can also produce coverage reports and pattern documentation to help integrate tests into CI pipelines.

When to use it

When you want to increase automated test coverage quickly
When starting TDD or adding tests to legacy code
When preparing code for CI/CD or release validation
When you need mock data and realistic fixtures generated
When you want consistent test patterns across a team

Best practices

Install and configure your target testing framework before generation
Select clear target functions or modules to focus generation and avoid noise
Review and curate generated assertions for domain-specific logic
Add custom scenarios and negative tests after automated generation
Integrate generated tests into CI and run coverage tools to validate results

Example use cases

Generate Jest unit tests for a new React component with mocked hooks and events
Create pytest suites for backend utility modules and database interaction mocks
Produce integration tests that combine multiple services and verify contract boundaries
Bootstrap tests for legacy Python or JavaScript code to identify brittle areas and missing edge cases
Iteratively expand test scenarios from a generated baseline during TDD sessions

FAQ

Which testing frameworks are supported?

The skill targets common frameworks including Jest, Vitest, Mocha, testing-library for frontend, and pytest for Python. Support depends on your project setup and installed packages.

How do I control the generated test scope?

Select specific files, functions, or modules as the generation target. Use Cascade configuration to prefer unit vs integration tests and to add or exclude scenario types.
