await Expect(locator).ToBeCheckedAsync();

参数

options LocatorAssertionsToBeCheckedOptions? (optional)

await Expect(Page.GetByTestId("todo-item").First).ToBeVisibleAsync();

// At least one of the two elements is visible, possibly both.

</div>

var locator = Page.Locator(".list > .component");

确保 Locator 指向包含给定文本的元素。在计算元素的文本内容时，将考虑所有嵌套元素。你也可以对该值使用正则表达式。

🌐 Ensures the Locator points to an element that contains the given text. All nested elements will be considered when computing the text content of the element. You can use regular expressions for the value as well.

用法

var locator = Page.Locator(".title");

定位器解析为元素列表。
此列表的子集中的元素分别包含预期数组中的文本。
匹配的元素子集与预期数组具有相同的顺序。
预期数组中的每个文本值都与列表中的某个元素匹配。

例如，考虑以下列表：

🌐 For example, consider the following list:

<ul>
  <li>Item Text 1</li>
  <li>Item Text 2</li>
  <li>Item Text 3</li>
</ul>

让我们看看如何使用断言：

🌐 Let's see how we can use the assertion:

// ✓ Contains the right items in the right order
await Expect(Page.Locator("ul > li")).ToContainTextAsync(new string[] {"Text 1", "Text 3"});

// ✖ Wrong order
await Expect(Page.Locator("ul > li")).ToContainTextAsync(new string[] {"Text 3", "Text 2"});

// ✖ No item contains this text
await Expect(Page.Locator("ul > li")).ToContainTextAsync(new string[] {"Some 33"});

// ✖ Locator points to the outer list element, not to the list items
await Expect(Page.Locator("ul")).ToContainTextAsync(new string[] {"Text 3"});

void #

详情

当 expected 参数是字符串时，Playwright 会在匹配前对实际文本和预期字符串中的空格和换行进行规范化。当使用正则表达式时，实际文本将按原样进行匹配。

🌐 When expected parameter is a string, Playwright will normalize whitespaces and line breaks both in the actual text and in the expected string before matching. When regular expression is used, the actual text is matched as is.
