javascript - 测试 Protractor 中的元素是否被禁用

Question

我们有一些应在应用程序上禁用的复选框。下面是 html 片段:

<label _ngcontent-c17="">
<input _ngcontent-c17="" checked="" disabled="" type="checkbox" value="">
    <span _ngcontent-c17="" class="ml-2"> Speech</span>
</label>

在应用程序上，我看到该复选框已选中且已禁用。

下面是我的代码片段，用于测试是否选中并禁用“语音”复选框:

 it(' Should validate the checked list on "Not Started" Page ', function () {
  expect(EC.elementToBeSelected(G.Speech_Checkbox_on_Services)).toBeTruthy();
  expect(G.Speech_Checkbox_on_Services.isEnabled()).toBeFalsy();
  expect(G.Speech_Checkbox_on_Services.getAttribute('disabled')).toBeTruthy();
  });

代码的最后两行应检查该复选框是否已禁用。但是，当我运行它时，两条线都失败了。我该如何解决这个问题？

Expected true to be falsy.
Expected null to be truthy.

Answer 1

如果你想检查复选框是否被选中和禁用

expect(G.Speech_Checkbox_on_Services.attr('checked')).toBeTruthy();
expect(G.Speech_Checkbox_on_Services.getAttribute('disabled')).toBe(true);

https://www.protractortest.org/#/api?view=webdriver.WebElement.prototype.isEnabled

希望这有帮助。
