angularjs – 在expect语句中一起添加变量

我有一些字符串,我使用量角器/ jasmine / angularJS提取并转换为整数.我现在正在尝试将这些添加在一起并在期望声明中进行比较.但是我这样做会有一些承诺错误.

var result0 = element.all(by.binding('InBoxes.InBox.Count')).first().getText().then(parseFloat);
    result0.then((value) => console.log("count: ",value));

    var result1 = element.all(by.binding('InBoxItem.Count')).get(0).getText().then(parseFloat);
    result1.then((value) => console.log("count: ",value));

    var result2 = element.all(by.binding('InBoxItem.Count')).get(1).getText().then(parseFloat);
    result2.then((value) => console.log("count: ",value));

    var result3 = element.all(by.binding('InBoxItem.Count')).get(2).getText().then(parseFloat);
    result3.then((value) => console.log("count: ",value)).then(expect(result1 + result2 + result3).toEqual(result0));

    //compare badge counts to InBox badge count
    expect(result1 + result2 + result3).toEqual(result0);
  });
 });
});

我收到以下承诺错误.我认为既然承诺已经满足并且下面的计数打印出来(41,7,14和20)我可以将底部3(reulst1-3)加在一起并与result0进行比较,结果是结果总数1-3 .我有这些承诺的时间,因为我是新手,并不太了解它们.
