PlaywrightAssertions

Playwright 为你提供了 Web 优先断言以及创建断言的便捷方法，这些断言将等待并重试，直到满足预期条件。

🌐 Playwright gives you Web-First Assertions with convenience methods for creating assertions that will wait and retry until the expected condition is met.

考虑以下示例：

🌐 Consider the following example:

import { test, expect } from '@playwright/test';

test('status becomes submitted', async ({ page }) => {
  // ...
  await page.locator('#submit-button').click();
  await expect(page.locator('.status')).toHaveText('Submitted');
});

Playwright 将会使用选择器 .status 重新测试节点，直到获取的节点包含 "Submitted" 文本。它会反复重新获取节点并进行检查，直到满足条件或达到超时时间。你可以将此超时作为一个选项传入。

🌐 Playwright will be re-testing the node with the selector .status until fetched Node has the "Submitted" text. It will be re-fetching the node and checking it over and over, until the condition is met or until the timeout is reached. You can pass this timeout as an option.

默认情况下，断言超时设置为 5 秒。

🌐 By default, the timeout for assertions is set to 5 seconds.
