期望抛出一个“ AssertionError：预期{对象（浏览器，然后，...）}等于真”]]

Question

我的测试期望值有误

我遇到此错误

[08:41:37] E/launcher - expected { Object (browser_, then, ...) } to equal true
[08:41:37] E/launcher - AssertionError: expected { Object (browser_, then, ...) } to equal true

这是我在步骤上的代码

  Then('Validate role {editrole} is selected', { timeout:30 * 1000 }, (editrole) => {
    var agentRoles = element.all(by.repeater('ctrl.roles'));
    agentRoles.each((role) => {
      return role.element(by.xpath(".//div[@class='md-whiteframe-1dp outset inset']/md-checkbox")).getText()
      .then((roleSelected) => {
        if (editrole === roleSelected) {
          expect(element(".//div[@class='md-whiteframe-1dp outset inset']/md-checkbox").isSelected()).to.be.equal(true);
        }
      });
    });
  });
我想做的是验证是否检查了一个元素，因此阅读另一项建议我看到.isSelected()是对此的最佳选择，但是我不确定为什么会引发此错误。

希望你能帮助我！

我的测试期望值有一个错误，我得到了这个错误[08:41:37] E /启动程序-期望{对象（浏览器，然后，...）}等于true [08:41： 37] E / launcher-AssertionError：预期的{...

似乎您正在尝试将对象与布尔值进行比较。您必须兑现承诺，否则必须使用“最终”（如果您使用“ chai”作为断言库）。下面的示例：
