我成功选择了一堆页面元素,现在我将所有这些元素传递给单独的页面模型和助手功能。
在后者上,我创建了一个辅助函数类,如下所示:
import { Selector } from 'testcafe';
export default class Helpers {
selectPageElement (elementName) {
const elementTitle = Selector ('div').child('h2');
const numberOfElements = elementTitle.count;
if (numberOfElements) {
for (let i = 0; i < numberOfElements; i++) {
if (elementTitle.nth(i) === 'aname') {
return elementTitle.nth(i);
}
}
} else {
return false;
}
}
}
然后在我的测试文件中,按如下方式调用该方法:
import { ClientFunction, Selector } from 'testcafe';
import Helpers from './helpers';
...
const helpers = new Helpers();
test('Test name', async t => {
...
await t
.click(helpers.selectPageElement('Element Name'));
});
但出现以下错误:
Action "selector" argument error:
Selector is expected to be initialized with a function, CSS selector string,
another Selector, node snapshot or a Promise returned by a Selector,
but undefined was passed.
我对ES6还是很陌生,所以我认为这与我调用该方法的方式有关。
答案 0 :(得分:4)
解决方案可能是:
export default class Helpers {
selectPageElement (elementName) {
return Selector('div > h2')
.withText(elementName);
}
}
