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:
using Microsoft.Playwright;
using Microsoft.Playwright.MSTest;
namespace PlaywrightTests;
[TestClass]
public class ExampleTests : PageTest
{
[TestMethod]
public async Task StatusBecomesSubmitted()
{
await Page.GetByRole(AriaRole.Button, new() { Name = "Submit" }).ClickAsync();
await Expect(Page.Locator(".status")).ToHaveTextAsync("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.
