# MATLAB Test Generator

This skill provides comprehensive guidelines for creating robust unit tests using the MATLAB Testing Framework. Generate test classes, test methods, and test suites following MATLAB best practices.

## When to Use This Skill

- Creating unit tests for MATLAB functions or classes
- Generating test suites for existing code
- Writing test cases with assertions and fixtures
- Creating parameterized tests
- Setting up test environments with setup/teardown methods
- When user requests testing, test coverage, or mentions unit tests

## MATLAB Testing Framework Overview

MATLAB supports multiple testing approaches:

1. **Script-Based Tests** - Simple test scripts with assertions
2. **Function-Based Tests** - Test functions with local functions for each test
3. **Class-Based Tests** - Full-featured test classes (recommended for complex testing)

## Test Class Structure

### Basic Test Class Template

```matlab
classdef MyFunctionTest < matlab.unittest.TestCase
    % Tests for myFunction

    properties (TestParameter)
        % Define parameters for parameterized tests
    end

    properties
        % Test fixtures and shared data
    end

    methods (TestClassSetup)
        % Runs once before all tests
    end

    methods (TestClassTeardown)
        % Runs once after all tests
    end

    methods (TestMethodSetup)
        % Runs before each test method
    end

    methods (TestMethodTeardown)
        % Runs after each test method
    end

    methods (Test)
        % Individual test methods
    end
end
```

## Critical Rules

### File Naming
- **Test files MUST end with `Test.m`** (e.g., `myFunctionTest.m`)
- Class name must match filename
- Follow PascalCase naming convention
- Place in `tests/` directory or alongside source with `Test` suffix

### Test Method Naming
- Use descriptive, readable names
- Start with lowercase letter
- Use camelCase
- Describe what is being tested
- Example: `testAdditionWithPositiveNumbers`

### Assertions
Always
