1. 测试基础概念

1.1 测试类型概述

测试类型 测试范围 测试目标 适用场景 单元测试 独立函数/类 功能正确性 业务逻辑验证 组件测试 UI组件 渲染/交互 界面功能验证 集成测试 多个模块 模块协作 功能流程验证 E2E测试 整个应用 用户场景 完整流程验证

1.2 测试工具配置

// package.json{ \"devDependencies\": { \"@ohos/hypium\": \"^1.0.0\", \"@ohos/test-runner\": \"^1.0.0\" }, \"scripts\": { \"test\": \"ets test\", \"test:unit\": \"ets test -u\", \"test:e2e\": \"ets test -e\" }}

2. 单元测试实现

2.1 基本测试用例

// utils.test.tsimport { describe, it, expect } from \'@ohos/hypium\';import { formatDate, calculateTotal } from \'../utils\';describe(\'Utils Functions\', () => { // 日期格式化测试 it(\'should format date correctly\', () => { const date = new Date(\'2024-01-01\'); expect(formatDate(date)).toBe(\'2024-01-01\'); }); // 总计计算测试 it(\'should calculate total correctly\', () => { const items = [ { price: 10, quantity: 2 }, { price: 20, quantity: 1 } ]; expect(calculateTotal(items)).toBe(40); }); // 边界条件测试 it(\'should handle empty items array\', () => { expect(calculateTotal([])).toBe(0); });});

2.2 异步测试

// service.test.tsimport { describe, it, expect } from \'@ohos/hypium\';import { UserService } from \'../services/user\';describe(\'UserService\', () => { let userService: UserService; beforeEach(() => { userService = new UserService(); }); // 异步请求测试 it(\'should fetch user data\', async () => { const user = await userService.getUser(\'123\'); expect(user).not.toBeNull(); expect(user.id).toBe(\'123\'); }); // 错误处理测试 it(\'should handle fetch error\', async () => { try { await userService.getUser(\'invalid\'); fail(\'Should throw error\'); } catch (error) { expect(error.message).toContain(\'User not found\'); } });});

2.3 Mock和Stub

// api.mock.tsimport { Mock } from \'@ohos/hypium\';export class ApiClientMock { @Mock async get(url: string): Promise<any> { if (url.includes(\'users\')) { return { id: \'123\', name: \'Test User\' }; } throw new Error(\'Not found\'); }}// service.test.tsdescribe(\'Service with Mocks\', () => { let service: UserService; let apiClient: ApiClientMock; beforeEach(() => { apiClient = new ApiClientMock(); service = new UserService(apiClient); }); it(\'should use mocked API client\', async () => { const user = await service.getUser(\'123\'); expect(user.name).toBe(\'Test User\'); expect(apiClient.get).toHaveBeenCalledWith(\'/users/123\'); });});

3. 组件测试方法

3.1 组件渲染测试

// button.test.etsimport { describe, it, expect } from \'@ohos/hypium\';import { CustomButton } from \'../components/Button\';describe(\'CustomButton Component\', () => { it(\'should render with correct text\', () => { const button = new CustomButton({ text: \'Click Me\' }); const wrapper = mount(button); expect(wrapper.text()).toBe(\'Click Me\'); }); it(\'should handle click event\', () => { const onClick = jest.fn(); const button = new CustomButton({ text: \'Click Me\', onClick }); const wrapper = mount(button); wrapper.trigger(\'click\'); expect(onClick).toHaveBeenCalled(); });});

3.2 状态变化测试

// counter.test.etsdescribe(\'Counter Component\', () => { it(\'should update count on button click\', async () => { const counter = new Counter(); const wrapper = mount(counter); expect(wrapper.find(\'#count\').text()).toBe(\'0\'); await wrapper.find(\'button\').trigger(\'click\'); expect(wrapper.find(\'#count\').text()).toBe(\'1\'); }); it(\'should handle state updates correctly\', async () => { const counter = new Counter(); const wrapper = mount(counter); // 多次点击测试 for (let i = 0; i < 3; i++) { await wrapper.find(\'button\').trigger(\'click\'); } expect(wrapper.find(\'#count\').text()).toBe(\'3\'); });});

4. 自动化测试框架

4.1 E2E测试配置

// e2e.config.tsexport default { specs: [\'./test/e2e/**/*.test.ts\'], capabilities: { platformName: \'HarmonyOS\', deviceType: \'phone\', app: \'./dist/app.hap\' }, framework: \'@ohos/test-runner\'};// login.e2e.tsdescribe(\'Login Flow\', () => { it(\'should login successfully\', async () => { await element(by.id(\'username\')) .typeText(\'testuser\'); await element(by.id(\'password\')) .typeText(\'password123\'); await element(by.text(\'Login\')) .tap(); // 验证登录成功 await expect(element(by.text(\'Welcome\'))) .toBeVisible(); });});

4.2 测试报告生成

// reporter.config.tsexport default { reporters: [ \'default\', [\'@ohos/test-reporter\', { outputDir: \'./test-results\', filename: \'test-report.html\', includeScreenshots: true }] ]};

5. 持续集成实践

5.1 CI配置示例

# .github/workflows/test.ymlname: Testson: push: branches: [ main ] pull_request: branches: [ main ]jobs: test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v2 - name: Setup Node.js uses: actions/setup-node@v2 with: node-version: \'14\' - name: Install dependencies run: npm install - name: Run tests run: npm test - name: Upload test results uses: actions/upload-artifact@v2 with: name: test-results path: test-results/

5.2 测试自动化脚本

// scripts/test-automation.tsimport { TestRunner } from \'@ohos/test-runner\';async function runTests() { const runner = new TestRunner({ // 配置测试环境 environment: { deviceId: process.env.DEVICE_ID, platform: \'HarmonyOS\' }, // 配置测试套件 suites: [ { name: \'Unit Tests\', pattern: \'test/unit/**/*.test.ts\' }, { name: \'E2E Tests\', pattern: \'test/e2e/**/*.test.ts\' } ], // 配置报告生成 reporters: [ { name: \'html\', outputFile: \'test-results/report.html\' }, { name: \'junit\', outputFile: \'test-results/junit.xml\' } ] }); try { const results = await runner.run(); console.log(\'Test Results:\', results); if (results.failed > 0) { process.exit(1); } } catch (error) { console.error(\'Test execution failed:\', error); process.exit(1); }}runTests();

5.3 最佳实践建议

1. 测试策略

   • 制定合理的测试计划
   • 确定测试覆盖率目标
   • 优先测试关键功能

2. 测试用例设计

   • 覆盖边界条件
   • 包含错误处理
   • 保持用例独立性

3. 测试维护

   • 定期更新测试用例
   • 清理过时的测试
   • 优化测试性能

4. 持续集成

   • 自动化测试执行
   • 及时反馈测试结果
   • 集成代码覆盖率报告

通过建立完善的测试体系，可以有效保证应用的质量和稳定性。在实际开发中，要根据项目特点选择合适的测试策略，并持续优化测试流程。
