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 将使用选择器 .status
重新测试节点,直到获取的节点具有 "Submitted"
文本。它将重新获取节点并一遍又一遍地检查它,直到满足条件或达到超时。你可以将此超时作为一个选项传递。
¥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.
