## 1. Test Strategy

### 1.1 Test Pyramid

Our testing approach follows the test pyramid:

     /\\
    /  \\  UI Tests (10%)
   /    \\  Critical user journeys, happy paths
  /------\\
 /        \\  Integration Tests (20%)
/          \\  API integration, data persistence, service layer

/------------\ / \ Unit Tests (70%) / \ ViewModels, Models, Utilities, Business Logic /------------------\

**Rationale**:
- **Unit Tests (70%)**: Fast, reliable, easy to maintain. Focus on business logic.
- **Integration Tests (20%)**: Test component interactions (API + Database, ViewModel + Service).
- **UI Tests (10%)**: Slow and brittle, only for critical user flows.

### 1.2 Testing Levels

**Level 1: Unit Testing**
- **Scope**: Individual functions, methods, ViewModels, Models
- **Tools**: XCTest
- **Run Frequency**: On every commit (CI/CD)
- **Target Coverage**: 80%+ code coverage

**Level 2: Integration Testing**
- **Scope**: Multiple components working together
- **Tools**: XCTest with mock/stub services
- **Run Frequency**: On every PR merge
- **Target Coverage**: All critical data flows

**Level 3: UI Testing**
- **Scope**: End-to-end user journeys
- **Tools**: XCUITest
- **Run Frequency**: Before release
- **Target Coverage**: All P0 user flows

**Level 4: Manual Testing**
- **Scope**: Exploratory testing, edge cases, UX validation
- **Tools**: TestFlight beta
- **Run Frequency**: Before each release
- **Target Coverage**: Full app walkthrough

### 1.3 Test Environments

**Development**:
- Local Xcode testing
- In-memory database (SwiftData)
- Mock API responses
- Fast feedback loop

**Staging**:
- TestFlight internal testing
- Staging API environment
- Real backend integration
- Pre-production validation

**Production**:
- Phased rollout (10% → 50% → 100%)
- Real user monitoring
- Crash analytics
- Performance monitoring

### 1.4 Testing Tools

| Tool | Purpose | When to Use |
|------|---------|-------------|
| XCTest | Unit & integration tests | Always |
| XCUITest | UI automation tests | Critical flows |
| TestFlight | Beta testing | Pre-release |
| Xcode Instruments | Performance profiling | Optimization phase |
| Accessibility Inspector | Accessibility audit | Every release |
| Network Link Conditioner | Network testing | Edge case testing |

## 2. Unit Test Cases

### 2.1 Data Model Tests

Test all `@Model` classes from ARCHITECTURE.md.

#### Test Suite: User Model

**File**: `[AppName]Tests/ModelTests/UserTests.swift`

| Test Case | Setup | Input | Expected Output | Priority |
|-----------|-------|-------|-----------------|----------|
| testUserInitialization | None | name: "John Doe", email: "[e-mail]" | User object created with UUID, timestamps set | P0 |
| testUserInitializationWithEmptyName | None | name: "", email: "[e-mail]" | User created but isValid returns false | P1 |
| testEmailValidation_Valid | User instance | email: "[e-mail]" | isValid returns true | P0 |
| testEmailValidation_Invalid | User instance | email: "invalid.com" | isValid returns false | P0 |
| testEmailValidation_Empty | User instance | email: "" | isValid returns false | P0 |
| testDisplayName_SingleName | User with name: "John" | Call displayName | Returns "John" | P1 |
| testDisplayName_FullName | User with name: "John Doe" | Call displayName | Returns "John" | P1 |
| testInitials_SingleName | User with name: "John" | Call initials | Returns "J" | P2 |
| testInitials_FullName | User with name: "John Doe" | Call initials | Returns "JD" | P2 |
| testUpdateProfile_Name | User instance | updateProfile(name: "Jane") | name updated, updatedAt changed | P1 |
| testUpdateProfile_Email | User instance | updateProfile(email: "[e-mail]") | email updated, updatedAt changed | P1 |
| testCodable_Encoding | User instance | Encode to JSON | Valid JSON with snake_case keys | P1 |
| testCodable_Decoding | JSON data | Decode from JSON | User object created correctly | P1 |

**Implementation Example**:

final class UserTests: XCTestCase {
    var sut: User!  // System Under Test

    override func setUp() {
        super.setUp()

        sut = User(name: "Test User", email: "[e-mail]")
    }

    override func tearDown() {
        // Cleanup runs after each test
        sut = nil
        super.tearDown()
    }

    // Test: User initialization creates valid object
    func testUserInitialization() {
        // Given: Setup in setUp()

        // When: User is initialized (done in setUp)

        // When
        let isValid = sut.isValid

        // Then
        XCTAssertTrue(isValid, "Valid email should pass validation")
    }

    // Test: Invalid email fails validation
    func testEmailValidation_Invalid() {
        // Given
        sut.email = "invalid.com"  // Missing @

        // When
        let isValid = sut.isValid

        // Then
        XCTAssertFalse(isValid, "Invalid email should fail validation")
    }

    // Test: Display name returns first name only
    func testDisplayName_FullName() {
        // Given
        sut.name = "John Doe"

        // When
        let displayName = sut.displayName

        // Then
        XCTAssertEqual(displayName, "John", "Display name should be first name only")
    }

    // Test: Initials are correctly generated
    func testInitials_FullName() {
        // Given
        sut.name = "John Doe"

        // When
        let initials = sut.initials

    func testUpdateProfile_Name() {
        // Given
        let originalUpdatedAt = sut.updatedAt
        sleep(1)  // Ensure timestamp changes

        // When
        sut.updateProfile(name: "Jane Doe")

        // Then
        XCTAssertEqual(sut.name, "Jane Doe")
        XCTAssertNotEqual(sut.updatedAt, originalUpdatedAt, "updatedAt should change")
    }

    // Test: Codable encoding produces valid JSON
    func testCodable_Encoding() throws {
        // Given: User from setUp

        // When
        let encoder = JSONEncoder()
        let data = try encoder.encode(sut)
        let json = try JSONSerialization.jsonObject(with: data) as? [String: Any]

        // Then
        XCTAssertNotNil(json)
        XCTAssertEqual(json?["name"] as? String, "Test User")
        XCTAssertEqual(json?["email"] as? String, "[e-mail]")

Default	Standard layout	Reference design	P0
Extra Large (XL)	Text larger, layout adjusts	Scrollable, no truncation	P0
Accessibility XXL	Text very large, stacked layout	Fully readable, scrollable	P1

Test Implementation:

func testDynamicType_ExtraLarge() {
    // Set large text size
    app.launchArguments += ["-UIPreferredContentSizeCategoryName", "UICTContentSizeCategoryAccessibilityXL"]
    app.launch()

    // Verify text is not truncated
    let title = app.staticTexts["Item Title"]
    XCTAssertTrue(title.exists)
    XCTAssertFalse(title.label.hasSuffix("..."), "Text should not be truncated")

    // Verify buttons are still tappable
    let addButton = app.buttons["Add Item"]
    XCTAssertTrue(addButton.exists)
    XCTAssertGreaterThan(addButton.frame.height, 44, "Button should be at least 44pt tall")

## Execution Instructions

When activated, follow these steps:

1. **Read All Specification Documents**

• Read docs/PRD.md (features, acceptance criteria, user stories)
• Read docs/IMPLEMENTATION_GUIDE.md (all ViewModels, models, services)
• Read docs/UX_SPEC.md (all screens, user flows, states)
• Read docs/ARCHITECTURE.md (testing strategy)

2. **Extract Testing Requirements**
- List all features to test (from PRD)
- List all ViewModels to unit test (from IMPLEMENTATION_GUIDE)
- List all models to unit test
- List all user flows to UI test (from UX_SPEC)
- Identify edge cases from UX_SPEC error states

3. **Generate Unit Test Cases**
- For each Model: test initialization, validation, methods, relationships, Codable
- For each ViewModel: test loading, errors, user actions, state management
- For each Service: test API calls, error handling, data operations

4. **Generate Integration Test Cases**
- Database + API sync
- ViewModel + Service integration
- Multi-component workflows

5. **Generate UI Test Cases**
- Critical user journeys (from PRD P0 features)
- Include all steps with assertions
- Provide complete XCUITest implementation

6. **Generate Accessibility Tests**
- VoiceOver labels for all interactive elements
- Dynamic Type scenarios
- Color contrast checks

7. **Generate Performance Tests**
- Launch time benchmarks
- Load testing scenarios
- Memory usage targets

8. **Document Edge Cases**

 ```

12. **Iterate Based on Feedback**
 If user requests changes:
 - Add missing test cases
 - Expand specific areas (e.g., more edge cases)
 - Provide more implementation examples
 - Adjust priorities

---

## Quality Guidelines

1. **Be Comprehensive**: Cover every feature from PRD
- Unit tests for all business logic
- UI tests for all critical flows
- Integration tests for key workflows
- Edge cases for all error scenarios

2. **Be Specific**: Test cases must be actionable
- Clear steps
- Clear expected results
- Clear pass/fail criteria
- Include test data

3. **Provide Code Examples**: Not just test case descriptions
- Show complete XCTest implementations
- Show XCUITest implementations
- Show mock objects
- Show test setup/teardown

4. **Think Like QA**: What could go wrong?
- Empty states
- Invalid inputs
- Network failures
- Permission denials
- Edge cases

5. **Consider Real Users**: Beta testing is crucial
- Real devices, real usage patterns
- Diverse user base
- Real-world network conditions
- Actual user feedback

6. **Enable Automation**: CI/CD integration
- Tests should run automatically
- Fast feedback loop
- Code coverage tracking
- Fail fast on critical issues

---

## Integration with Workflow

This skill is typically:
- **Fifth step** in specification generation
- Activated after PRD, Architecture, UX, and Implementation Guide are complete
- Followed by release-spec
- Critical for ensuring quality before App Store submission

The test specification ensures the app works correctly and provides confidence for release.

---

## Notes

- Every feature in PRD must have corresponding test cases
- Test early, test often - don't wait until the end
- Automated tests save time in the long run
- Manual testing still crucial for UX validation
- Beta testing provides real-world feedback
- Bug tracking is part of the testing process
- Performance and accessibility are not optional
- Security testing must be thorough
- Document all test cases for repeatability
