Playwright
Playwright 是一个测试框架,它允许你使用单一的 API,自动的在 Chromium、Firefox 和 WebKit 环境中运行测试用例,你可以使用它来编写 E2E 测试。
在 Modern.js 中使用 Playwright 需要先安装依赖,可以执行以下命令:
上述命令会自动安装 Playwright 依赖,并通过一系列提示帮助你在项目中安装和配置,包括添加一个 playwright.config.ts
文件。
按照默认配置创建后,可以在项目中看到以下文件:
tests/example.spec.ts
import { test, expect } from '@playwright/test';
test('has title', async ({ page }) => {
await page.goto('https://playwright.dev/');
// Expect a title "to contain" a substring.
await expect(page).toHaveTitle(/Playwright/);
});
test('get started link', async ({ page }) => {
await page.goto('https://playwright.dev/');
// Click the get started link.
await page.getByRole('link', { name: 'Get started' }).click();
// Expects page to have a heading with the name of Installation.
await expect(
page.getByRole('heading', { name: 'Installation' }),
).toBeVisible();
});
这是默认的测试文件,现在创建一些新的页面,并测试它们。
创建 E2E 测试
首先创建两张 Modern.js 的页面。
routes/page.tsx
import { Link } from '@modern-js/runtime/router';
const Index = () => (
<div>
<h1>Home</h1>
<Link to="/about">About</Link>
</div>
);
export default Index;
routes/about/page.tsx
import { Link } from '@modern-js/runtime/router';
const Index = () => (
<div>
<h1>About</h1>
<Link to="/">Home</Link>
</div>
);
export default Index;
接下来,添加测试用例,来保证你页面的链接能够正常工作。
tests/example.spec.ts
import { test, expect } from '@playwright/test'
test('should navigate to the about page', async ({ page }) => {
// Start from the index page (the baseURL is set via the webServer in the playwright.config.ts)
await page.goto('http://localhost:8080/')
// Find an element with the text 'About' and click on it
await page.click('text=About')
// The new URL should be "/about" (baseURL is used there)
await expect(page).toHaveURL('http://localhost:8080/about')
// The new page should contain an h1 with "About"
await expect(page.locator('h1')).toContainText('About')
})
运行测试用例
Playwright 需要你的 Modern.js 服务器保持运行。我们推荐在生产环境产物下运行你的测试用例,你可以执行 pnpm run build
和 pnpm run serve
在本地模拟生产环境。
info Starting production server...
> Local: http://localhost:8080/
> Network: http://10.94.59.30:8080/
当项目正常构建运行后,可以在另一个终端内执行 npx playwright test
,运行 Playwright 用例:
Running 3 tests using 3 workers
3 passed (2.0s)
To open last HTML report run:
npx playwright show-report
