Angular2量角器类型错误：this.flow_.getSchedulingFrame_不是一个函数

Question

尝试使用量角器上运行的应用程序Angular2集成测试：

protractor.conf.js

exports.config = { 
    baseUrl: 'http://localhost:3000', 
    seleniumAddress: 'http://localhost:4444/wd/hub', 
    specs: [ 
    'src/app/e2e/contact.e2e.js' 
    ], 
    framework: 'jasmine', 
    useAllAngular2AppRoots: true 
}; 

我的测试文件： contact.e2e.js

describe('App', function(){ 
    it('should render the contact section', function() { 
    browser.get('/'); 
    expect(true).toBe(true); 
    }); 
}); 

我得到的错误：

Message:

奇怪的是，这只是发生在我的Mac，当我通过它运行良好，我的詹金斯服务器上泊坞窗运行测试。 帮助将不胜感激。 在此先感谢。

更新

我的量角器是不是全球性的，并且我跑量角器的版本：版本4.0.14

Answer 1

有几个项目来解决：

devDependencies ：量角器4.0.11使用selenium-webdriver 2.53.1。在项目中你也有selenium-webdriver 2.47.0作为devDependency是不寻常的。

堆栈跟踪：错误selenium-webdriver/lib/goog/../webdriver/promise.js是犯罪嫌疑人，因为/lib/goog/不说量角器将使用^ 4.0.11中硒的webdriver节点模块中存在。我怀疑你使用的是旧版本的量角器。

• 量角器4.0.11使用硒的webdriver 2.53.1 - 没有lib/goog/
• 量角器2.5.1使用硒的webdriver 2.47.0 - 确实有一个文件夹中有lib/goog/
• 量角器1.8 .0使用selenium-webdriver 2.44.0 - 确实有一个文件夹lib/goog/

我会检查你如何运行量角器。我认为你是从全球范围内运行它，并且应该尝试protractor --version来验证。

也是有帮助的是脚本添加到您的package.json

"scripts": { 
    "e2e": "protractor some/path/to/conf.js" 
    } 

然后用npm run e2e执行此。这将确保您使用项目中的项目node_modules使用量角器。

更新：

答案如上所述，我改变了2.47.0确实有路径/lib/goog/。我回答的时间真的很晚，可能写得不正确。这可能是因为我做了npm i -S [email protected]^2.47.0。不知怎的，你已经说过你想要^ 2.47.0但是如果你收缩包装2.47.0，那么这将阻止胡萝卜下载最后一个小版本。

对答案的改进。下面的堆栈跟踪引用了两个不同版本的selenium-webdriver。属于量角器和不同版本的硒-webdriver。不在量角器中的硒 - 驱动器指的是路径lib/goog/。

     at promise.Promise.then (/Users/yarivkatz/Development/workspace/bugeez/bugeez-lp-final/node_modules/selenium-webdriver/lib/goog/../webdriver/promise.js:592:15) 
     at ManagedPromise.invokeThen_ (/Users/yarivkatz/Development/workspace/bugeez/bugeez-lp-final/node_modules/protractor/node_modules/selenium-webdriver/lib/promise.js:1193:12) 

正如上面在更新中所述，我相信在你的selenium-webdriver版本中有东西被锁定。此外，由于您有两个版本的selenium-webdriver，因此您正在调用node_modules/protractor/node_modules/selenium-webdriver，并且不知何故调用了node_modules/selenium-webdriver/lib/goog/。

请删除devDependency，将它从shrinkwrap中删除，然后重新安装依赖项。
