如果指定了直接节点ip，则IE11测试运行但在指定网格集线器URL时失败

Question

我使用nodejs selenium-standalone，我有：

1）使用role = hub

在Mac上运行的selenium-standalone

2）在Mac上使用role = node运行selenium-standalone（在本地Mac浏览器上运行测试）

3）Windows 10安装在parallels桌面上，运行带有role = node

的selenium-standalone

4）IE11已针对本文https://github.com/SeleniumHQ/selenium/wiki/InternetExplorerDriver#required-configuration

进行了配置

我的测试中有gridUrl配置（yandex gemini），当我将它设置为windows node url（http://10.211.55.4:5555/wd/hub）时，IE11测试工作正常。但是当我将gridUrl设置为正确的值（意味着本地网格集线器127.0.0.1:4444/wd/hub）时，IE11将打开卡在＆＃34;这是WebDriver服务器的初始启动页面。＆＃34;和＆＃34;只允许本地连接＆＃34;在控制台中。在这种情况下，所有其他Windows浏览器都可以正常工作（chrome，firefox，edge）。在mac selenium网格集线器控制台或windows selenium节点控制台中没有任何错误 - 似乎网格集线器不知何故错误地尝试调用Windows节点IEDriver。

启动selenium的命令：

1）MacOS中心：

java -jar 3.8.1-server.jar -role hub

2）Windows10节点：

java -jar 3.8.1-server.jar -role node -hub http://192.168.1.4:4444/grid/register

在此之后，我可以在MacOS http://127.0.0.1:4444/grid/console上看到所有节点和浏览器。

我使用selenium 3.8.1，IEdriver x64 3.8.0

Windows node cmd screenshot：

使用配置的MacOS网格集线器控制台屏幕截图：

集线器和节点的DEBUG模式输出：

Windows节点控制台成功输出（不使用网格集线器直接连接）：

Answer 1

我可以清楚地看到您的 Selenium Grid Hub 配置存在一些不匹配，并且 Selenium Grid Node 注册 {{1} } 如下：

• Selenium Grid Hub 日志说：

  Selenium Grid Hub

• Nodes should register to http://10.37.129.2:4444/grid/register/ 日志说：

  Selenium Grid Node

此外，当您启动节点以使用Registering the node to the hub: http://192.168.1.4:4444/grid/register 和IEDriverServer时，您已使用默认命令：

Internet Explorer

这是您在 FAILED 用例中看不到 java -jar 3.8.1-server.jar -role node -hub http://192.168.1.4:4444/grid/register 的确切原因，如下所示：

INFO - Detected dialect: W3C

您需要提及您打算使用的Started InternetExplorerDriver server (64-bit) 3.8.0.0 Listening on port 15388 Only local connections are allowed 22:14:37.269 DEBUG - Polling http://localhost:15388/status 22:14:37.269 DEBUG - sun.net.www.MessageHeader@14906bf5 pairs: {GET /status HTTP/1.1: null}{User-Agent: Java/1.8.0_161}{Host: localhost:15388}{Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2}{Connection: keep-alive} 22:14:37.269 DEBUG - sun.net.www.MessageHeader@4b81f27 pairs: {null: HTTP/1.1 200 OK}{Content-Length: 185}{Content-Type: application/json; charset=UTF-8}{Cache-Control: no-cache}{Vary: Accept-Charset, Accept-Encoding, Accept-Language, Accept}{Accept-Ranges: bytes}{Connection: close} 22:14:37.283 DEBUG - CookieSpec selected: default 22:14:37.283 DEBUG - Auth cache not set in the context 变体，如下所示：

WebDriver

因此，您的日志消息将包含：

java -Dwebdriver.ie.driver=IEDriverServer.exe -jar selenium-server-standalone-3.8.1.jar -role node -hub http://192.168.1.50:4444/grid/register

您可以看到详细讨论here Doug Simmons明确提到：

解决方案

按照上述步骤配置 The server (grid node) needs to be started with the system property -- not the client i.e. you need to point the node to the geckodriver installation on the node 和 Selenium Grid Hub ：

• 启动 Selenium Grid Node ：

  Selenium Grid Hub

• 应生成以下日志：

  java -jar selenium-server-standalone-3.8.1.jar -role hub
  

• 观察 19:40:59.322 INFO - Selenium build info: version: '3.8.1', revision: '6e95a6684b' 19:40:59.324 INFO - Launching Selenium Grid hub 2018-01-23 19:41:01.710:INFO::main: Logging initialized @2960ms to org.seleniumhq.jetty9.util.log.StdErrLog 19:41:01.764 INFO - Will listen on 4444 2018-01-23 19:41:01.881:INFO:osjs.Server:main: jetty-9.4.7.v20170914 2018-01-23 19:41:01.923:INFO:osjs.session:main: DefaultSessionIdManager workerName=node0 2018-01-23 19:41:01.924:INFO:osjs.session:main: No SessionScavenger set, using defaults 2018-01-23 19:41:01.928:INFO:osjs.session:main: Scavenging every 600000ms 2018-01-23 19:41:01.937:INFO:osjsh.ContextHandler:main: Started o.s.j.s.ServletContextHandler@1b68b9a4{/,null,AVAILABLE} 2018-01-23 19:41:01.959:INFO:osjs.AbstractConnector:main: Started ServerConnecto r@157632c9{HTTP/1.1,[http/1.1]}{0.0.0.0:4444} 2018-01-23 19:41:01.960:INFO:osjs.Server:main: Started @3211ms 19:41:01.960 INFO - Nodes should register to http://192.168.1.50:4444/grid/register/ 19:41:01.961 INFO - Selenium Grid hub is up and running ：http://192.168.1.50:4444

• 通过Selenium Grid Hub URI打开 Selenium Grid Hub Console ：

  URL

• http://192.168.1.50:4444/grid/console 的快照：

• Selenium Grid Hub Config 1 的快照：

• 为 Selenium Grid Hub Config 2 启动 Selenium Grid Node ：

  IE11

• 确保在http://192.168.1.50:4444/grid/register
