有没有办法用量角器解决多个承诺? [英] Is there a way to resolve multiple promises with Protractor?

问题描述

我有这个:

element(by.id('x')).sendKeys('xxx').then(function(text) {
  element(by.id('y')).sendKeys('yyy').then(function(text) {
     element(by.id('z')).sendKeys('zzz').then(function(text) {
        expect(element(by.id('myButton')).isEnabled()).toBe(true);
     })
  });
});

当元素x"、y"和z"都有值时，按钮myButton"被启用.我的理解是 sendKeys 返回一个承诺.

The button 'myButton' is enabled when the elements 'x', 'y' and 'z' all have values. It's my understanding that sendKeys returns a promise.

那么这是我可以检查是否启用了依赖于所有三个字段中的数据的myButton"的唯一方法?

So is this the only way that I can check if 'myButton' which depends on data in all the three fields is enabled?

推荐答案

你不需要链接任何 promise，因为量角器会等到所有语句都完成:https://github.com/angular/protractor/blob/master/docs/control-flow.md

You don't need to chain any promises because protractor will wait until all the statements are done: https://github.com/angular/protractor/blob/master/docs/control-flow.md

element(by.id('x')).sendKeys('xxx');
element(by.id('y')).sendKeys('yyy');
element(by.id('z')).sendKeys('zzz');
expect(element(by.id('myButton'));

如果您想解决多个承诺，请使用:

If you want to resolve multiple promises use:

var webdriver = require('selenium-webdriver');
webdriver.promise.fullyResolved(promises);

例如:https://github.com/angular/protractor/blob/d15d35a82a5a2/lib/protractor.js#L327
