Question

我试图为AngularJS应用程序编写一些e2e规范。我在test/e2e/test_spec.js中有一个Jasmine规范：

describe('basic functionality', function() {
  it('loads the home page', function() {
    browser.get('/');
    expect(browser.getCurrentUrl()).toMatch(/localhost/);
  });
});

运行规范时的终端输出：

> protractor protractor.config.js
Using the selenium server at http://localhost:4444/wd/hub
[launcher] Running 1 instances of WebDriver
basic functionality
  loads the home page - fail


Failures:

  1) basic functionality loads the home page
   Message:
     Error: waiting for page to load for 10000ms

   Stacktrace:

[launcher] 0 instance(s) of WebDriver still running
[launcher] chrome #1 failed 1 test(s)
[launcher] overall: 1 failed spec(s)
[launcher] Process exited with error code 1

当控制台位于[launcher] Running 1 instances of WebDriver时，Chrome会打开并显示索引页面几分之一秒，然后在地址栏中更改为data:text/html,<html></html>的空白页。

Chrome screenshot

这是我的protractor.config.js：

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  capabilities: {
    'browserName': 'chrome'
  },
  specs: 'test/e2e/**/*_spec.js',
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000,
    isVerbose: true
  },
  allScriptsTimeout: 20000,
  onPrepare: function() {
    return browser.driver.get("http://localhost:8100");
  }
};

我的webdriver-manager似乎是最新的，虽然该工具似乎没有办法输出版本号。

> webdriver-manager status
selenium standalone is up to date
chromedriver is up to date
IEDriver is not present

为什么规范失败？

修改：这是onPrepare被注释掉时打印到终端的内容：

> protractor protractor.config.js

编辑2 ：当我browser.get("http://google.com")时，Chrome会短暂显示data:和data:text/html,<html></html>页面，重定向到Google，然后超时寻找Angular。

Answer 1

在baseUrl: 'http://localhost:8100'文件中设置protractor.config.js。来自Protractor Reference Config：

正在测试的应用程序的基本URL。使用相对路径调用protractor.get（）将以此为前缀。

Answer 2

这是量角器https://github.com/angular/protractor/issues/5103中的偶发性打开错误

代替这个

browser.get('http://juliemr.github.io/protractor-demo/');

使用它解决了我的问题。

browser.driver.get('http://juliemr.github.io/protractor-demo/');

Answer 3

我在 chrome 中遇到了这个问题。我在某处读到量角器从 data:text/html,<html></html> 页面开始。调用 browser.get(...) 会导航离开该页面。我的想法是在我的基本网址上打开 chrome。我通过将它添加到这样的功能中来实现这一点：

capabilities: {
  'browserName': 'chrome',
  'chromeOptions': {
    'args': ['--app=www.yourBaseUrl.com']
  }
},

这有点像黑客，但它似乎成功了。

量角器在加载页面后立即重定向并超时
