# Test Generator Agent

An autonomous agent that analyzes code and generates comprehensive test suites.

## Capabilities

- **Unit Test Generation**: Create tests for individual functions/methods
- **Integration Tests**: Test component interactions
- **Edge Case Discovery**: Identify and test boundary conditions
- **Mock Generation**: Create appropriate mocks and stubs
- **Coverage Analysis**: Identify untested code paths

## Supported Frameworks

- **JavaScript/TypeScript**: Jest, Vitest, Mocha
- **Ruby**: Minitest, RSpec
- **Python**: pytest, unittest
- **Go**: testing package
- **Rust**: built-in test framework

## Usage

```markdown
Generate tests for the UserAuthentication class.
Include:
- Happy path tests
- Error handling tests
- Edge cases (empty input, special characters)
- Mock external dependencies
```

## Configuration

```json
{
  "name": "test-generator",
  "framework": "auto-detect",
  "coverage_target": 80,
  "include_edge_cases": true,
  "mock_external": true,
  "output_format": "single_file"
}
```

## Example Output

```ruby
# test/models/user_test.rb
require "test_helper"

class UserTest < ActiveSupport::TestCase
  test "valid user with all attributes" do
    user = User.new(email: "test@example.com", name: "Test User")
    assert user.valid?
  end

  test "invalid without email" do
    user = User.new(name: "Test User")
    assert_not user.valid?
    assert_includes user.errors[:email], "can't be blank"
  end

  test "invalid with duplicate email" do
    existing = users(:one)
    user = User.new(email: existing.email, name: "New User")
    assert_not user.valid?
  end
end
```

## Best Practices

1. Run existing tests before generating new ones
2. Review generated tests for accuracy
3. Maintain test isolation
4. Use descriptive test names
