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 static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat;

public class TestExample {
// ...
@Test
void statusBecomesSubmitted() {
// ...
page.locator("#submit-button").click();
assertThat(page.locator(".status")).hasText("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.
