||||
|
- ✅ **4 mock levels** implemented |
||||
|
- ✅ **Comprehensive coverage** of ImageViewer functionality |
||||
|
- ✅ **Behavior-focused testing** approach working |
||||
|
|
||||
|
### Target Metrics |
||||
|
- [ ] **100% test pass rate** (fix remaining test) |
||||
|
- [ ] **10+ components** with mock units |
||||
|
- [ ] **< 100ms** average test execution time |
||||
|
- [ ] **90%+ code coverage** for critical components |

||||
|
## Notes 📝 |
||||
|
|
||||
|
### Lessons Learned |
||||
|
- Vue 3 reactivity can be tricky with computed properties in tests |
||||
|
- Direct method calls work better than `trigger()` for complex events |
||||
|
- Mock levels provide excellent flexibility for different testing needs |
||||
|
- Behavior-focused testing is more maintainable than implementation-focused |
||||
|
|
||||
|
### Technical Debt |
||||
|
- Some TypeScript linter errors in mock files (non-blocking) |
||||
|
- Event simulation needs better abstraction |
||||
|
- Test environment could be more robust |
||||
|
- Mock documentation could be more comprehensive |

# Component Mock Units Documentation |
||||
|
|
||||
|
## Overview |
||||
|
|
||||
|
This directory contains comprehensive mock units for Vue component testing, |
||||
|
designed for behavior-focused testing patterns. The mocks provide multiple |
||||
|
levels of complexity to support different testing scenarios and requirements. |
||||
|
|
||||
|
## Mock Architecture |
||||
|
|
||||
|
### Mock Levels Pattern |
||||
|
|
||||
|
All component mocks follow a consistent 4-level architecture: |
||||
|
|
||||
|
#### 1. Simple Mock (`createSimple[Component]Mock`) |
||||
|
**Use Case**: Basic component testing, prop validation, minimal functionality |
||||
|
- Basic template with minimal structure |
||||
|
- Essential props and events |
||||
|
- No complex behavior simulation |
||||
|
- Fast execution for quick tests |
||||
|
|
||||
|
#### 2. Standard Mock (`createStandard[Component]Mock`) |
||||
|
**Use Case**: Most component testing scenarios, realistic behavior |
||||
|
- Full template with realistic structure |
||||
|
- Platform detection and feature simulation |
||||
|
- Realistic user interactions |
||||
|
- Balanced performance and functionality |
||||
|
|
||||
|
#### 3. Complex Mock (`createComplex[Component]Mock`) |
||||
|
**Use Case**: Error handling, edge cases, advanced scenarios |
||||
|
- Error state simulation |
||||
|
- Retry functionality |
||||
|
- Loading state management |
||||
|
- Error event emissions |
||||
|
|
||||
|
#### 4. Integration Mock (`createIntegration[Component]Mock`) |
||||
|
**Use Case**: Full workflow testing, analytics, performance monitoring |
||||
|
- Complete user workflow simulation |
||||
|
- Analytics tracking |
||||
|
- Performance monitoring |
||||
|
- Comprehensive event handling |
||||
|
|
||||
|
## Mock Data Factories |
||||
|
|
||||
|
### Standard Factory Pattern |
||||
|
|
||||
|
```typescript |
||||
|
// Generic mock data factory |
||||
|
export const createMock[Component]Data = (overrides = {}) => ({ |
||||
|
// Default props |
||||
|
prop1: "default-value", |
||||
|
prop2: false, |
||||
|
// Component-specific defaults |
||||
|
...overrides, |
||||
|
}); |
||||
|
|
||||
|
// Platform-specific factories |
||||
|
export const createMockUserAgent = (overrides = {}) => ({ |
||||
|
getOS: () => ({ name: "iOS", version: "15.0" }), |
||||
|
getBrowser: () => ({ name: "Safari", version: "15.0" }), |
||||
|
getDevice: () => ({ type: "mobile", model: "iPhone" }), |
||||
|
...overrides, |
||||
|
}); |
||||
|
|
||||
|
// API mocks |
||||
|
export const createMockNavigator = (overrides = {}) => ({ |
||||
|
share: jest.fn().mockResolvedValue(undefined), |
||||
|
...overrides, |
||||
|
}); |
||||
|
|
||||
|
export const createMockWindow = (overrides = {}) => ({ |
||||
|
open: jest.fn(), |
||||
|
URL: { |
||||
|
createObjectURL: jest.fn().mockReturnValue("blob:mock-url"), |
||||
|
revokeObjectURL: jest.fn(), |
||||
|
}, |
||||
|
...overrides, |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
## Component Mock Template |
||||
|
|
||||
|
### Basic Structure |
||||
|
|
||||
|
```typescript |
||||
|
/** |
||||
|
* [Component] Component Mock |
||||
|
* |
||||
|
* Comprehensive mock implementation for [Component] component testing. |
||||
|
* Provides multiple mock levels for different testing scenarios and |
||||
|
* behavior-focused test patterns. |

``` |
||||
|
|
||||
|
## Usage Patterns |
||||
|
|
||||
|
### 1. Basic Component Testing |
||||
|
|
||||
|
```typescript |
||||
|
describe("Basic Component Testing", () => { |
||||
|
it("renders with basic props", () => { |
||||
|
const createWrapper = create[Component]MockWrapper("simple"); |
||||
|
const wrapper = createWrapper({ |
||||
|
prop1: "test-value", |
||||
|
prop2: true, |
||||
|
}); |
||||
|
|
||||
|
expect(wrapper.exists()).toBe(true); |
||||
|
expect(wrapper.find(".component-mock").exists()).toBe(true); |
||||
|
}); |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
### 2. Platform-Specific Testing |
||||
|
|
||||
|
```typescript |
||||
|
describe("Platform Detection", () => { |
||||
|
it("shows platform-specific features", () => { |
||||
|
const createWrapper = create[Component]MockWrapper("standard"); |
||||
|
const wrapper = createWrapper(createMock[Component]Data()); |
||||
|
|
||||
|
wrapper.vm.userAgent = createMockUserAgent({ |
||||
|
getOS: () => ({ name: "iOS" }) |
||||
|
}); |
||||
|
|
||||
|
expect(wrapper.vm.isMobile).toBe(true); |
||||
|
}); |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
### 3. Error Scenario Testing |
||||
|
|
||||
|
```typescript |
||||
|
describe("Error Handling", () => { |
||||
|
it("handles API failures gracefully", async () => { |
||||
|
const createWrapper = create[Component]MockWrapper("standard"); |
||||
|
const mockApi = vi.fn().mockRejectedValue(new Error("API failed")); |
||||
|
|
||||
|
const wrapper = createWrapper(createMock[Component]Data()); |
||||
|
|
||||
|
// Trigger error scenario |
||||
|
await wrapper.vm.handleApiCall(); |
||||
|
|
||||
|
expect(mockApi).toHaveBeenCalled(); |
||||
|
expect(wrapper.vm.hasError).toBe(true); |
||||
|
}); |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
### 4. Integration Testing |
||||
|
|
||||
|
```typescript |
||||
|
describe("Full User Workflow", () => { |
||||
|
it("completes full user journey", async () => { |
||||
|
const createWrapper = create[Component]MockWrapper("integration"); |
||||
|
const wrapper = createWrapper(createMock[Component]Data({ isOpen: false })); |
||||
|
|
||||
|
// Step 1: Initialize |
||||
|
await wrapper.setProps({ isOpen: true }); |
||||
|
expect(wrapper.vm.getAnalytics().openCount).toBe(1); |
||||
|
|
||||
|
// Step 2: User interaction |
||||
|
const button = wrapper.find('[data-testid="action-button"]'); |
||||
|
await button.trigger("click"); |
||||
|
|
||||
|
// Step 3: Verify results |
||||
|
expect(wrapper.vm.getAnalytics().actionCount).toBe(1); |
||||
|
}); |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
## Best Practices |
||||
|
|
||||
|
### 1. Choose Appropriate Mock Level |
||||
|
|
||||
|
- Use **simple** for basic prop validation and rendering tests |
||||
|
- Use **standard** for most component behavior tests |
||||
|
- Use **complex** for error handling and edge case tests |
||||
|
- Use **integration** for full workflow and analytics tests |
||||
|
|
||||
|
### 2. Mock Global Objects |
||||
|
|
||||
|
```typescript |
||||
|
beforeEach(() => { |
||||
|
mockNavigator = createMockNavigator(); |
||||
|
mockWindow = createMockWindow(); |
||||
|
global.navigator = mockNavigator; |
||||
|
global.window = mockWindow; |
||||
|
vi.clearAllMocks(); |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
### 3. Test Platform Detection |
||||
|
|
||||
|
```typescript |
||||
|
const platforms = [ |
||||
|
{ name: "iOS", expected: true }, |
||||
|
{ name: "Android", expected: true }, |
||||
|
{ name: "Windows", expected: false }, |
||||
|
]; |
||||
|
|
||||
|
platforms.forEach(({ name, expected }) => { |
||||
|
wrapper.vm.userAgent = createMockUserAgent({ |
||||
|
getOS: () => ({ name, version: "1.0" }), |
||||
|
}); |
||||
|
expect(wrapper.vm.isMobile).toBe(expected); |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
### 4. Test Error Scenarios |
||||
|
|
||||
|
```typescript |
||||
|
// Test API failure |
||||
|
const mockApi = vi.fn().mockRejectedValue(new Error("API failed")); |
||||
|
mockNavigator.share = mockApi; |
||||
|
|
||||
|
// Test component error |
||||
|
const element = wrapper.find('[data-testid="component-element"]'); |
||||
|
await element.trigger("error"); |
||||
|
expect(wrapper.vm.hasError).toBe(true); |
||||
|
``` |
||||
|
|
||||
|
### 5. Use Test Data Factories |
||||
|
|
||||
|
```typescript |
||||
|
// Instead of hardcoded data |
||||
|
const wrapper = createWrapper({ |
||||
|
prop1: "test-value", |
||||
|
prop2: true, |
||||
|
}); |
||||
|
|
||||
|
// Use factory functions |
||||
|
const wrapper = createWrapper(createMock[Component]Data({ |
||||
|
prop1: "test-value", |
||||
|
prop2: true, |
||||
|
})); |
||||
|
``` |
||||
|
|
||||
|
## Performance Considerations |
||||
|
|
||||
|
### 1. Mock Level Performance |
||||
|
|
||||
|
- **Simple**: Fastest execution, minimal overhead |
||||
|
- **Standard**: Good balance of features and performance |
||||
|
- **Complex**: Moderate overhead for error handling |
||||
|
- **Integration**: Highest overhead for analytics tracking |
||||
|
|
||||
|
### 2. Test Execution Tips |
||||
|
|
||||
|
```typescript |
||||
|
// Use simple mock for quick tests |
||||
|
const createWrapper = create[Component]MockWrapper("simple"); |
||||
|
|
||||
|
// Use standard mock for most tests |
||||
|
const createWrapper = create[Component]MockWrapper("standard"); |
||||
|
|
||||
|
// Use complex/integration only when needed |
||||
|
const createWrapper = create[Component]MockWrapper("complex"); |
||||
|
``` |
||||
|
|
||||
|
## Accessibility Testing |
||||
|
|
||||
|
### 1. ARIA Labels |
||||
|
|
||||
|
```typescript |
||||
|
it("has proper ARIA labels", () => { |
||||
|
const wrapper = createWrapper(createMock[Component]Data()); |
||||
|
const element = wrapper.find('[data-testid="component-element"]'); |
||||
|
expect(element.attributes("alt")).toBe("descriptive text"); |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
### 2. Keyboard Navigation |
||||
|
|
||||
|
```typescript |
||||
|
it("supports keyboard navigation", async () => { |
||||
|
const wrapper = createWrapper(createMock[Component]Data()); |
||||
|
const button = wrapper.find('[data-testid="action-button"]'); |
||||
|
|
||||
|
await button.trigger("keydown.enter"); |
||||
|
expect(wrapper.emitted("action")).toBeTruthy(); |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
## Troubleshooting |
||||
|
|
||||
|
### Common Issues |
||||
|
|
||||
|
1. **Mock not found**: Ensure proper import path |
||||
|
```typescript |
||||
|
import { create[Component]MockWrapper } from "./__mocks__/[Component].mock"; |
||||
|
``` |
||||
|
|
||||
|
2. **Global objects not mocked**: Set up in beforeEach |
||||
|
```typescript |
||||
|
beforeEach(() => { |
||||
|
global.navigator = createMockNavigator(); |
||||
|
global.window = createMockWindow(); |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
3. **User agent not working**: Set userAgent property directly |
||||
|
```typescript |
||||
|
wrapper.vm.userAgent = createMockUserAgent({ |
||||
|
getOS: () => ({ name: "iOS" }) |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
4. **Events not emitting**: Use async/await for event triggers |
||||
|
```typescript |
||||
|
await button.trigger("click"); |
||||
|
await wrapper.vm.$nextTick(); |
||||
|
``` |
||||
|
|
||||
|
### Debug Tips |
||||
|
|
||||
|
1. **Check mock level**: Verify you're using the right mock level |
||||
|
2. **Inspect wrapper**: Use `console.log(wrapper.html())` to see rendered output |
||||
|
3. **Check props**: Use `console.log(wrapper.props())` to verify prop values |
||||
|
4. **Monitor events**: Use `console.log(wrapper.emitted())` to see emitted events |
||||
|
|
||||
|
## Migration from Legacy Tests |
||||
|
|
||||
|
### Before (Legacy) |
||||
|
|
||||
|
```typescript |
||||
|
// Old way - direct component testing |
||||
|
const wrapper = mount(Component, { |
||||
|
props: { prop1: "test", prop2: true }, |
||||
|
global: { stubs: { "font-awesome": true } } |
||||
|
}); |
||||
|
``` |
||||
|
|
||||
|
### After (Mock Units) |
||||
|
|
||||
|
```typescript |
||||
|
// New way - behavior-focused testing |
||||
|
const createWrapper = create[Component]MockWrapper("standard"); |
||||
|
const wrapper = createWrapper(createMock[Component]Data({ prop1: "test" })); |
||||
|
|
||||
|
// Test behavior, not implementation |
||||
|
expect(wrapper.vm.isMobile).toBe(false); |
||||
|
expect(wrapper.find('[data-testid="feature"]').exists()).toBe(false); |
||||
|
``` |
||||
|
|
||||
|
## Contributing |
||||
|
|
||||
|
When adding new mocks or updating existing ones: |
||||
|
|
||||
|
1. **Follow naming conventions**: Use descriptive names with `create` prefix |
||||
|
2. **Add documentation**: Include JSDoc comments for all functions |
||||
|
3. **Test all levels**: Ensure all mock levels work correctly |
||||
|
4. **Update examples**: Add usage examples for new features |
||||
|
5. **Maintain consistency**: Follow existing patterns and structure |
||||
|
|
||||
|
## Security Considerations |
||||
|
|
||||
|
- Mocks should not expose sensitive data |
||||
|
- Use realistic but safe test data |
||||
|
- Avoid hardcoded credentials or tokens |
||||
|
- Sanitize any user-provided data in mocks |
||||
|
|
||||
|
## Example: ImageViewer Implementation |
||||
|
|
||||
|
The `ImageViewer.mock.ts` file demonstrates this pattern in practice: |
||||
|
|
||||
|
- **4 mock levels** with increasing complexity |
||||
|
- **Mock data factories** for realistic test data |
||||
|
- **Platform detection** for mobile vs desktop testing |
||||
|
- **Error handling** for share API and image loading failures |
||||
|
- **Analytics tracking** for performance monitoring |
||||
|
- **Comprehensive tests** showing all usage patterns |
||||
|
|
||||
|
This serves as a template for creating mocks for other components in the project. |
