【问题描述】:
我为我的页面模型开发了一组助手。
这就是 DOM 的样子:
<div id="parentA">
<div class="child yes">hello</div>
<div class="child">world</div>
</div>
<div id="parentB">
<div class="child no">hello</div>
<div class="child">world</div>
</div>
现在我想检查#parentA 或#parentB 中的.child 元素之一。
import { Selector } from "testcafe";
fixture `children`
.page `http://localhost:8080/index.html`;
// an example of what I expect.
// this is not how i want to write tests.
test("hard-coded: child in A has class 'yes'", async (t) => {
const yesChild = Selector("#parentA .child").withText("hello");
t.expect((await yesChild.classNames).includes("yes"));
});
// helper function for the page model (in a shared module later)
function getParent(name: string) {
return Selector(`#parent${name}`);
}
// helper function for the page model (in a shared module later)
function getChild() {
return Selector(".child");
}
// this is how I want to write tests.
test("parametric-find: child in A has class 'yes'", async (t) => {
const parent = getParent("A");
const child = getChild().withText("hello");
const yesChild = parent.find(child); // there is no overload for find that takes another Selector.
t.expect((await yesChild.classNames).includes("yes"));
});
我认为一种解决方案可能是这样的函数:
async function withinParent(child: Selector, parent: Selector): Selector {
// how should I implement this?
}
另一种解决方案可能是创建 filterFunction 的高阶函数:
test("parametric-find-descendantChild: child in A has class 'yes'", async (t) => {
const parent = getParent("A");
const child = getChild().withText("hello");
const yesChild = parent.find(descendantChild(child));
t.expect((await yesChild.classNames).includes("yes"));
});
function descendantChild(child: Selector): (node: Element) => boolean {
// how should I implement this?
}
但我能想到的所有方法都会导致死胡同。
-
parent和child可以匹配多个元素 - 没有简单的方法可以访问选择器选择的元素,以便将其与另一个选择器进行比较
- 如何比较选择器?
- 在元素级别上运行的函数/回调在浏览器中执行。我将选择器或选择器匹配的元素传递给浏览器函数有多冷?
好吧,我应该写一个功能请求,还是有一个聪明的方法来做到这一点?
