E:\Work\Test>

我正在使用带有量角器测试工具的grunt任务运行器。我有两个问题。

当我运行测试时，它会出现上述错误。 (Error before Jasmine started.)，但之后所有测试套件都按预期运行良好。那么这个错误意味着什么？
我在conf.js文件中使用directConnect:true。为什么它在控制台中显示如 -

启动Selenium服务器

启动Selenium服务器：http://127.0.0.1:4444

以下错误是什么意思？

Jasmine started

来自绑定接口的

：memory_instrumentation :: mojom :: Coordinator 暴露者：content_browser

更新

这是我的Package.json文件

以下是您遇到的问题。您有一个test-e2e任务启动了protractor:start webdriver-manager update和webdriver-manager start

现在这将下载chromedriver。并尝试移动到命名版本。

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

另一个进程已经在运行，这使得此举无法进行。所以你需要杀死所有现有的chromedriver.exe。启动任务也可能是启动硒网格，这在您的情况下是不需要的。你应该做的只是让量角器控制发射。删除任何自行执行webdriver管理器的任务

启动Protractor工具会先抛出一些错误，但在此之后运行正常
