端對端測試
測試完整的使用者工作流程
概觀
端對端測試可驗證應用程式中的完整使用者工作流程。
使用 Playwright
設定
bash
# Install Playwright
npm install -D @playwright/test
# Initialize
npx playwright install
組態設定
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)
},
})撰寫測試
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')
})測試對話方塊
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()
})測試視窗行為
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)
})最佳實務
✅ 建議做法
- 測試關鍵使用者流程
- 使用 data-testid 屬性
- 清理測試資料
- 在 CI/CD 中執行測試
- 測試錯誤情境
- 讓各項測試保持獨立
❌ 請勿這樣做
- 不要測試實作細節
- 不要撰寫脆弱的選取器
- 不要略過清理步驟
- 不要忽略不穩定的測試
- 不要測試所有內容
執行端對端測試
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 整合
