Impossible to registering the node to the hub with SetupTeardownProxy

[mikyone]

Hello I got an error when on my log file. It seems if I add a new node with selenium grid extra pointing on my hub. I got this error below in the log. (I changed the ip address by XXX:XX:XX:XX).

16:52:37.429 INFO [17] org.openqa.grid.internal.utils.SelfRegisteringRemote - Registering the node to the hub: http://XXX:XX:XX:XX:4444/grid/register 16:52:37.444 INFO [17] org.openqa.grid.internal.utils.SelfRegisteringRemote - Couldn't register this node: Error sending the registration request: The hub responded with 500:Could not initialize class com.groupon.seleniumgridextras.grid.proxies.SetupTeardownProxy

My hub config file is

{
  "port": 4444,
  "newSessionWaitTimeout": 25000,
  "servlets": [
    "com.groupon.seleniumgridextras.grid.servlets.SeleniumGridExtrasServlet",
    "com.groupon.seleniumgridextras.grid.servlets.ProxyStatusJsonServlet"
  ],
  "capabilityMatcher": "org.openqa.grid.internal.utils.DefaultCapabilityMatcher",
  "throwOnCapabilityNotPresent": true,
  "nodePolling": 5000,
  "cleanUpCycle": 5000,
  "browserTimeout": 120000,
  "timeout": 120000,
  "maxSession": 5
}

And my node config file is :

{
  "capabilities": [
    {
      "seleniumProtocol": "WebDriver",
      "browserName": "firefox",
      "maxInstances": 3,
      "version": "37",
      "platform": "VISTA"
    },
    {
      "seleniumProtocol": "WebDriver",
      "browserName": "internet explorer",
      "maxInstances": 1,
      "version": "8",
      "platform": "VISTA"
    },
    {
      "seleniumProtocol": "WebDriver",
      "browserName": "chrome",
      "maxInstances": 3,
      "version": "43",
      "platform": "VISTA"
    }
  ],
  "configuration": {
    "proxy": "com.groupon.seleniumgridextras.grid.proxies.SetupTeardownProxy",
    "maxSession": 3,
    "port": 5555,
    "register": true,
    "unregisterIfStillDownAfter": 10000,
    "hubPort": 4444,
    "hubHost": "XXX:XX:XX:XX",
    "nodeStatusCheckTimeout": 10000,
    "downPollingLimit": 0
  },
  "loadedFromFile": "node_5555.json"
}

Do you have any clue ?

Are you running your hub with Selenium Grid extras? Both node(s) and hub need to be run by it because they share some classes that are needed.

I made a test as a command line with jar and it works... I was trying to do it on intellij with the selenium project. I was wondering how do you embed the source code of selenium project in your own project ?

There are 2 embeding points, a servlette (to give some code via browser, such a new console view or an API status endpoint) and proxy (which will allow you to hook into the execution of pre and post tests)

Here is an example of a Servlette, the commented out code would return a json file with a list of all connected nodes https://github.com/groupon/Selenium-Grid-Extras/blob/master/SeleniumGridExtras/src/main/java/com/groupon/seleniumgridextras/grid/servlets/ProxyStatusJsonServlet.java

Here is an example of a proxy, that hooks into pre/post test https://github.com/groupon/Selenium-Grid-Extras/blob/master/SeleniumGridExtras/src/main/java/com/groupon/seleniumgridextras/grid/proxies/SetupTeardownProxy.java

don't forget to check the grid's jar for the flags on how to attach the servlette and or proxies into a new instance of node or hub
