量角器在加载页面后立即重定向并超时

Protractor redirects and times out immediately after loading page

我正在尝试为 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/);
  });
});

规格为运行时的终端输出:

> 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:

[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 打开并显示索引页面几分之一秒,然后变为空白页面,地址为 data:text/html,<html></html>酒吧.

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,尽管该工具似乎无法输出版本号。

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

为什么规范失败了?

编辑: 这是 onPrepare 被注释掉时打印到终端的内容:

> protractor protractor.config.js

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

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

A base URL for your application under test. Calls to protractor.get() with relative paths will be prepended with this.

量角器零星开放的bug https://github.com/angular/protractor/issues/5103

而不是这个

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/'); 

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(...) 离开该页面。我的想法是在我的基地 url 上打开 chrome。我通过将它添加到这样的功能来实现这一点:

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

有点乱,但似乎已经成功了。
