## Description

Generate test templates for unit tests, integration tests, and UI tests using Swift Testing and XCTest. Use when adding tests to iOS/macOS apps.

# Test Generator

Generate test templates for unit tests, integration tests, and UI tests in iOS/macOS apps.

## When This Skill Activates

Use this skill when the user:
- Asks to "add tests" or "write tests" for their app
- Asks about unit testing, UI testing, or XCTest
- Wants to test ViewModels, services, or repositories
- Mentions TDD or test-driven development
- Asks about Swift Testing framework (`@Test`, `#expect`, `@Suite`)
- Wants mock objects or test helpers
- Asks about snapshot testing or preview tests

## Decision Tree

```
What tests do you need?
|
+-- Unit tests for business logic
|   +-- Swift Testing (@Test, #expect) -- recommended for iOS 16+
|   +-- XCTest -- for iOS 13-15 support or existing XCTest projects
|
+-- Integration tests (component interactions)
|   +-- Protocol-based mocks with dependency injection
|
+-- UI tests
|   +-- XCUITest with Screen Object pattern
|
+-- Snapshot/preview tests
    +-- PreviewSnapshots or swift-snapshot-testing
```

## Pre-Generation Checks

### 1. Project Context Detection
- [ ] Identify existing test targets and test runner
- [ ] Detect testing framework already in use (Swift Testing vs XCTest)
- [ ] Verify deployment target (Swift Testing requires iOS 16+ / macOS 13+)
- [ ] Identify project architecture pattern (MVVM, TCA, Repository, etc.)
- [ ] Locate source file directories

### 2. Conflict Detection
Search for existing test infrastructure:
```
Glob: **/*Tests.swift, **/*Tests/**/*.swift, **/*Spec.swift
Grep: "import XCTest" or "import Testing" or "@Suite" or "@Test"
Grep: "MockItemRepository" or "protocol.*Repository" or "class Mock"
```

If existing tests are found:
- Ask user whether to follow the existing framework (XCTest vs Swift Testing) or migrate
- Check for existing mock objects to reuse or extend
- Identify existing test helpers and factories
