量角器“在等待量角器与页面同步时出错”浏览Angular站点

Question

 exports.config = {
      seleniumAddress: 'http://localhost:4444/wd/hub',
      specs: ['test-spec.js']
    };

describe('Protractor Demo App', function() {
    it('should have a title', function() {
        browser.get('http://juliemr.github.io/protractor-demo/');
        expect(browser.getTitle()).toEqual('Super Calculator');
    });
});

运行protactor量角器配置.js时，出现以下错误：

Error: Error while waiting for Protractor to sync with the page: "both angularJS testability and angular testability are undefined.  This could be either because this is a non-angular page or because your test involves client-side navigation, which can interfere with Protractor's bootstrapping.

量角器版本6.0使用selenium版本4，这是第一个放弃对控制流支持的selenium版本。控制流允许量角器执行如下代码

browser.get('http://google.com');
expect(browser.getTitle()).toEqual('Super Calculator');

以同步的方式。

configuration.js

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['test-spec.js']
};

test-spec.js

describe('Protractor Demo App', function() {
    it('should have a title', async function() {
        await browser.get('http://juliemr.github.io/protractor-demo/');
        expect(await browser.getTitle()).toEqual('Super Calculator');
    });
});

更新：如果您尝试将selenium_promise_manager:true添加到配置.js中，这可能允许您在编写演示时继续进行演示。
