我正在使用页面对象模型来开发剧作家的自动化测试。因此,我正在构建一个类来保存我的定位器并公开定位器,但不一定是使用的选择器。定位器是否有办法共享其选择器?
exports.MyWebPageModel = class MyWebPageModel {
constructor(page) {
this.myMultiSelect = page.locator('#select-group select');
this.submitButton = page.locator('#submit-btn');
}
}

test('validate multi-select submission', ({page}) -> {
const myPage = new MyWebPageModel(page);
const selectChoices = ['choice1', 'choice2', 'choice4'];
await myPage.myMultiSelect.selectOptions(selectedChoices);
Promise.all([
page.waitForNavigation(),
myPage.submitButton.click()
]);
/* do tests on new page, click it's back button to return to previous page */
const allSelectedValues = await page.$eval(myPage.myMultiSelect.???, e => Array.from(e.selectedOptions).map(option => option.value)); // get the selected options from select element
expect(allSelectedValues).toEqual(selectedChoices); // verify the selected options matches selectChoices.
});

通过执行以下操作:
const myLoc = page.locator('#myElement');
Object.getOwnPropertyNames(myLoc).forEach(prop => {
console.log(prop + " = " + row_locator[prop]);
});

我发现有一个_selector,它返回用于 Locator 对象的内部选择器。
所以答案是使用定位器的“私有”属性_selector。这是生成定位器错误时使用的值。
所以,给定一个表:
<table id="colors">
<thead>
<trow>
<th>Key</th>
<th>Color</th>
</trow>
</thead>
<tbody>
<trow>
<td>R</td><td>Red</td>
</trow>
<trow>
<td>B</td><td>Blue</td>
</trow>
<trow>
<td>G</td><td>Green</td>
</trow>
</tbody>
</table>

并且,也许您可以按如下方式构建剧作家对象:
exports.ColorTable = class ColorTable {
constructor(page) {
this.page = page;
this.table = this.page.locator("#colors");
this.tableData = this.table.locator('tbody tr');
}
}

结果如下
const myT = new ColorTable(page);
console.log(myT.tableData._selector);

可能看起来像: Locator@#colors >> tbody tr
