引言
在AI驱动的现代前端应用中,组件质量直接决定了用户体验的成败。DevCloudFE/MateChat作为前端智能化场景解决方案UI库,承载着构建高质量AI应用的重任。本文将深入探讨MateChat项目的单元测试策略,为开发者提供一套完整的质量保障体系。
测试架构设计
分层测试策略
MateChat采用分层测试架构,确保每个组件都能得到充分的测试覆盖:
技术栈选择
组件单元测试实践
测试文件结构
packages/components/├── Bubble/│ ├── __tests__/│ │ ├── Bubble.spec.ts # 组件测试│ │ └── bubble-constants.spec.ts # 常量测试│ ├── Bubble.vue│ └── bubble-constants.ts
核心组件测试示例
以List组件的useList
组合函数为例:
// use-list.spec.tsimport { describe, it, expect, vi } from \'vitest\'import { useList } from \'./use-list\'import { ListDirection } from \'./list-types\'describe(\'useList\', () => { it(\'should handle item click correctly\', () => { const mockEmits = vi.fn() const props = { data: [ { value: \'1\', label: \'Item 1\', disabled: false }, { value: \'2\', label: \'Item 2\', disabled: true } ], selectable: true, enableShortKey: false } const { onItemClick } = useList(props, mockEmits) // 测试正常点击 onItemClick(props.data[0]) expect(mockEmits).toHaveBeenCalledWith(\'select\', expect.objectContaining({ value: \'1\', label: \'Item 1\' })) // 测试禁用项点击 mockEmits.mockClear() onItemClick(props.data[1]) expect(mockEmits).not.toHaveBeenCalled() }) it(\'should handle keyboard navigation\', async () => { const mockEmits = vi.fn() const props = { data: [ { value: \'1\', label: \'Item 1\' }, { value: \'2\', label: \'Item 2\' } ], enableShortKey: true, selectable: true } const { onKeyDown } = useList(props, mockEmits) // 模拟向下箭头键 const downEvent = new KeyboardEvent(\'keydown\', { code: \'ArrowDown\' }) onKeyDown(downEvent) // 模拟回车键选择 const enterEvent = new KeyboardEvent(\'keydown\', { code: \'Enter\' }) onKeyDown(enterEvent) expect(mockEmits).toHaveBeenCalledWith(\'select\', expect.any(Object)) })})
AI组件特殊测试策略
对于AI相关组件(如Prompt、Mention),需要特殊的测试策略:
// prompt.spec.tsdescribe(\'Prompt组件AI功能测试\', () => { it(\'should handle AI response formatting\', async () => { const wrapper = mount(Prompt, { props: { suggestions: [\'建议1\', \'建议2\'] } }) // 模拟AI响应 await wrapper.vm.handleAIResponse(\'这是AI的回复内容\') expect(wrapper.emitted(\'response\')).toBeTruthy() expect(wrapper.emitted(\'response\')[0]).toEqual([ expect.objectContaining({ content: \'这是AI的回复内容\', formatted: true }) ]) }) it(\'should handle markdown rendering in AI responses\', () => { const markdownContent = \'# 标题\\n\\n这是**加粗**文本\' const { result } = renderMarkdown(markdownContent) expect(result).toContain(\'标题
\') expect(result).toContain(\'加粗\') })})
测试配置与工具链
Vitest配置优化
// vitest.config.jsimport { defineConfig } from \'vitest/config\'import vue from \'@vitejs/plugin-vue\'export default defineConfig({ plugins: [vue()], test: { environment: \'jsdom\', globals: true, coverage: { provider: \'v8\', reporter: [\'text\', \'json\', \'html\'], exclude: [ \'**/node_modules/**\', \'**/dist/**\', \'**/__tests__/**\', \'**/*.d.ts\' ] }, setupFiles: [\'./tests/setup.ts\'] }})
测试覆盖率要求
持续集成测试流程
GitHub Actions工作流
name: Test Suiteon: [push, pull_request]jobs: test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: pnpm/action-setup@v2 - uses: actions/setup-node@v3 with: node-version: \'18\' cache: \'pnpm\' - name: Install dependencies run: pnpm install - name: Run unit tests run: pnpm test:unit - name: Run coverage run: pnpm test:coverage - name: Upload coverage uses: codecov/codecov-action@v3
测试质量门禁
最佳实践与常见问题
测试编写原则
-
AAA模式(Arrange-Act-Assert)
// Arrangeconst props = { /* 测试数据 */ }const wrapper = mount(Component, { props })// Act await wrapper.find(\'button\').trigger(\'click\')// Assertexpect(wrapper.emitted(\'event\')).toBeTruthy()
-
避免实现细节测试
// 错误:测试内部实现expect(wrapper.vm.internalState).toBe(true)// 正确:测试公开行为expect(wrapper.html()).toContain(\'expected content\')
-
使用合适的测试替身
// 使用vi.fn()代替真实函数const mockHandler = vi.fn()const wrapper = mount(Component, { props: { onClick: mockHandler }})
常见问题解决方案
await nextTick()
await wrapper.vm.$nextTick()
await trigger(\'click\')
vi.useFakeTimers()
