端到端测试
测试完整的用户工作流
概述
端到端测试用于验证应用程序中的完整用户工作流。
使用 Playwright
设置
bash
# Install Playwright
npm install -D @playwright/test
# Initialize
npx playwright install
配置
javascript
// playwright.config.js
import { defineConfig } from '@playwright/test'
export default defineConfig({
testDir: './e2e',
use: {
baseURL: 'http://localhost:9245', // Wails v3 dev server (default port)
},
})编写测试
javascript
// e2e/app.spec.js
import { test, expect } from '@playwright/test'
test('create note', async ({ page }) => {
await page.goto('/')
// Click new note button
await page.click('#new-note-btn')
// Fill in title
await page.fill('#note-title', 'Test Note')
// Fill in content
await page.fill('#note-content', 'Test content')
// Verify note appears in list
await expect(page.locator('.note-item')).toContainText('Test Note')
})
test('delete note', async ({ page }) => {
await page.goto('/')
// Create a note first
await page.click('#new-note-btn')
await page.fill('#note-title', 'To Delete')
// Delete it
await page.click('#delete-btn')
// Confirm dialog
page.on('dialog', dialog => dialog.accept())
// Verify it's gone
await expect(page.locator('.note-item')).not.toContainText('To Delete')
})测试对话框
javascript
test('file save dialog', async ({ page }) => {
await page.goto('/')
// Intercept file dialog
page.on('filechooser', async (fileChooser) => {
await fileChooser.setFiles('/path/to/test/file.json')
})
// Trigger save
await page.click('#save-btn')
// Verify success message
await expect(page.locator('.success-message')).toBeVisible()
})测试窗口行为
javascript
test('window state', async ({ page }) => {
await page.goto('/')
// Test window title
await expect(page).toHaveTitle('My App')
// Test window size
const size = await page.viewportSize()
expect(size.width).toBe(800)
expect(size.height).toBe(600)
})最佳实践
✅ 应该做
- 测试关键用户流程
- 使用 data-testid 属性
- 清理测试数据
- 在 CI/CD 中运行测试
- 测试错误场景
- 确保测试相互独立
❌ 不应该做
- 不要测试实现细节
- 不要编写脆弱的选择器
- 不要跳过清理工作
- 不要忽视不稳定的测试
- 不要测试所有内容
运行端到端测试
bash
# Run all tests
npx playwright test
# Run in headed mode
npx playwright test --headed
# Run specific test
npx playwright test e2e/app.spec.js
# Debug mode
npx playwright test --debug
CI/CD 集成
