getByAltText(
// If you're using `screen`, then skip the container argument:
container: HTMLElement,
text: TextMatch,
options?: {
exact?: boolean = true,
normalizer?: NormalizerFn,
}): HTMLElement
这将返回具有给定 `alt` 文本的元素(通常是 `<img>`)。请注意,它只支持接受 `alt` 属性的元素或 自定义元素(因为我们不知道自定义元素是否实现了 `alt`):<img>
,<input>
,以及 <area>
(有意排除 <applet>
,因为它已弃用)。
<img alt="Incredibles 2 Poster" src="/incredibles-2.png" />
