我正在使用量角器測試工具使用grunt任務運行器。我有兩個問題。啓動量角器工具先引發一些錯誤，但在此之後運行正常

當我運行測試時，它給出了上述錯誤。 (Error before Jasmine started.)，但在此之後，所有測試套件都按預期運行良好。那麼這個錯誤意味着什麼？
我在我的conf.js文件中使用directConnect:true。爲什麼它顯示在控制檯喜歡 -

啓動硒服務器

啓動Selenium服務器：http://127.0.0.1:4444

什麼是下面的錯誤假設意味着什麼？

Jasmine started 
[656:2544:0930/113649.269:ERROR:shader_disk_cache.cc(237)] Failed to create shader cache entry: -2

從綁定界面：memory_instrumentation :: mojom ::協調員通過暴露：content_browser

UPDATE

這是我的package.json文件

發佈'package.json'以及js配置爲量角器 –

我發佈了我的package.json文件。 [Tarun]（https://stackoverflow.com/users/2830850/tarun-lalwani） –

所以下面是你有的問題。你有一個任務test-e2e它啓動protractor:start這是運行webdriver-manager update和webdriver-manager start

現在這將下載chromedriver。並嘗試移動到命名版本。

E:\Work\Test\node_modules\protractor\node_modules\webdriver-manager\selenium\chromedriver.exe' -> 'E:\Work\Test\node_modules\protractor\node_modules\webdriver-manager\selenium\chromedriver_2.26.exe

而另一個過程已經在運行，這使得此舉變得不可能。所以你需要殺死所有現有的chromedriver.exe。此外，啓動任務可能會啓動您的情況下不需要的硒網格。你應該做的只是讓量角器控制發射。刪除任何執行webdriver管理器本身的任務

我們可以同步這些任務嗎，比如第一個webdriver-manager更新，然後是webdriver-manager start？ –

是的，那會在你的grunt文件中出現。請參閱https://gruntjs.com/creating-tasks –
