Question

我是量角器的新手，正在阅读教程。设置和第0步对我来说运行正常，但我在 Step 1 中遇到意外错误：

$ protractor conf.js

我向spec.js添加了调试语句，以尝试识别它无法找到的元素。它似乎找到了两个输入字段和按钮，但没有找到输出字段。

这是我的spec.js：

// spec.js
describe('Protractor Demo App', function() {
  it('should add one and two', function() {
    browser.get('http://juliemr.github.io/protractor-demo/');
    console.log("seeking `first`");
    element(by.model('first')).sendKeys(1);
    console.log("seeking `second`");
    element(by.model('second')).sendKeys(2);

    console.log("seeking `gobutton`");
    element(by.id('gobutton')).click();

    console.log("seeking `latest`");
    expect(element(by.binding('latest')).getText()).toEqual('5'); // This is wrong!
  });
});

我做错了吗？

Answer 1

现在这里可能发生的事情很少

元素返回的元素（by.binding（'latest'））不正确
有多个元素匹配元素（by.binding（'latest'））并且第一个元素正在返回给您

屏幕上看不到返回给您的元素。 Chromedriver在对用户可见的元素采取操作时非常具体。如果该元素对用户不可见，则自动化不应该模拟对其的操作（不是100％为真，因为仍然可以采取某些操作）。

因此，请确保您获得正确的元素并且没有多重匹配
