## 1. Test Framework Architecture
DevEco Testing is built on the JUnit5 extension mechanism and adopts a layered testing strategy:
1. Unit Testing Layer: Covers business logic components (Service/Manager)
2. Component Testing Layer: Validates Ability/Extension functionalities
3. System Testing Layer: Verifies multi-device collaborative scenarios
Core capabilities include:
* ArkTS Test Engine: Supports asynchronous task validation
* Device Shadow Mode: Simulates multi-device collaborative environments
* Data Sandbox: Isolates test data from production environments
## 2. Unit Testing Implementation
### 1. Test Case Specifications
``` typescript ```
``` // Example: Asynchronous Task Validation @Test async function testAsyncTask() { const result = await DataService.fetchData(); assertEquals(result.code, 200); assertTrue(Array.isArray(result.data)); } ```
### 2. Mock Service Configuration
Dependency isolation using @Mock annotations:
``` typescript ```
``` // Mock network service @Mock class NetworkService { @InjectMock async fetchData(): Promise<Data> { return { code: 200, data: mockData }; } } ```
### 3. Test Coverage
Line-level coverage reporting:
``` markdown ```
``` ------------------------- Test Coverage Report ------------------------- Module | Line Coverage | Branch Coverage ----------------------------------------------- CoreService | 82% | 75% UIComponent | 91% | 88% NetworkModule | 67% | 63% ```
## 3. UI Automation Testing
### 1. Component Localization Strategies
| Strategy | Use Case | Example Code | | :---------- | :----------------------- | :-------------------------------------------- | | resource-id | Stable element ID | component.findComponentById('btn_submit') | | text | Dynamic content matching | component.findComponentsByText('Submit') | | xpath | Complex hierarchy | component.findByXPath('//[@text="Confirm"]') |
### 2. Gesture Simulation
``` typescript ```
``` // Swipe Operation Example test('Swipe Test', async () => { await gesture.swipe({ startX: 500, startY: 1500, endX: 500, endY: 500, duration: 800 }); await expect(component).toHaveText('New Content'); }); ```
### 3. Exception Scenarios
Network fluctuation simulation: device.simulateNetwork('3G')
* Memory pressure testing: device.fillMemory(80%)
* Low battery testing: device.setBatteryLevel(15%)
## 4. CI/CD Integration
### 1. Pipeline Configuration
``` yaml ```
``` # devops-ci.yaml stages: - name: unit-test script: - npm run build - npm run test:unit -- --coverage
- name: ui-test
device:
type: emulator
config: phone_2k
script:
- npm run test:ui -- --headless
```### 2. Test Reporting
Output formats:
``` bash ```
``` test-results/ ├── junit.xml # CI system integration └── report.html # Visual analysis report ```
