How are you running your tests ? Can you please share the exact maven command line args (options) that you are passing via Jenkins ?

It would be good if you could please help create a testng suite xml file wherein you have bumped up the verbose tag's value to 2 or higher.

See here for some reference.

Thanks & Regards

Try changing 

<suite name="UOLO Test Suite">

to 

<suite name="UOLO Test Suite" verbose="3">

in your suite file and run again. You should start seeing the exception details. You should already be seeing the exception information in the TestNG generated reports as well.

[⇜Krishnan Mahadevan⇝]

Since am not sure if its due to a faulty chromedriver installation or a faulty chrome browser installation itself [ The error is due to one of those reasons ], you would need to try and do the following manually once :

1. Try spawning the chrome browser manually by invoking it via the command line. You should be able to spawn the browser.

2. If the browser spawns, then try spawning the chromedriver manually and you should see an output as below :

Starting ChromeDriver 2.21.371459 (36d3d07f660ff2bc1bf28a75d1cdabed0983e7c4) on port 9515

Only local connections are allowed.

The last part of the test would be to check if chromedriver is able to spawn the chrome browser properly. For that do the following from a terminal :

1. Spawn the chromedriver binary.

2. From another terminal invoke the below curl POST command [ You should see a chrome browser pop out ]

curl --data "{\"desiredCapabilities\": {}}" --header "Content-type: application/json"  http://localhost:9515/session

Iam getting below error for running command

 curl --data "{\"desiredCapabilities\": {}}" --header "Content-type: application/json"  http://localhost:9515/session

output:

curl: (7) Failed to connect to localhost port 9515: Connection refused

When I replace localhost with my server ip address (http://52.77.152.154:9515/session) and hit enter then still shows as waiting for command line input .

Could you please send me command to Spawn the chromedriver binary and chrome browser manually

Shruthi

Could you please send me command to Spawn the chromedriver binary and chrome browser manually 

There is no special command to spawn the chromedriver binary. If its location has been added in your PATH variable, merely typing "chromedriver" in a terminal will invoke it. If not then you would need to navigate to the directory wherein chromedriver binary resides using "cd" command and then type "chromedriver".

That should do.

If you want chromedriver to give you "verbose" logs, then you start it with : chromedriver --verbose [ You can type chromedriver -h to see all the possible command line arguments ]

When I replace localhost with my server ip address (http://52.77.152.154:9515/session) and hit enter then still shows as waiting for command line input .

I guess you are perhaps experiencing the problem that is detailed in this SO link (The link is about OSX but I think its a problem with your loopback address in /etc/hosts file ) which is why curl doesn't work with localhost. That's immaterial (or is it) !

When you changed the IP to your server IP address did you see a browser window open up ? If you saw that, then it basically means that your environment setup is working fine i.e., you have correctly installed chrome browser and your chromedriver binary is successfully able to spawn a chrome browser via a JSONWireProtocol command [ the curl command is essentially what selenium will also do internally ]

Thanks & Regards

Thanks for replying Krishnan Mahadevan,

1.when I navigate to the directory wherein chromedriver binary resides using "cd" command and then type "chromedriver".throws an error as 

bash: chromedriver: command not found

when I type like ./chromedriver

output shown as Starting ChromeDriver (v2.9.248304) on port 9515  but I do not see browser opening up 

2.When I type  google-chrome it shows as [11434:11434:0602/114735:ERROR:browser_main_loop.cc(271)] Gtk: cannot open display:

You should take a look at this post and see if that helps : http://superuser.com/a/392263

I think now its confirmed that your machine hasn't been setup properly to spawn a UI application.

Chromedriver 2.9 is very old. You might want to go to version 2.21

When I googled ,I got to know that I am suppose to install Xvfb to open any browsers on amazon AWS EC2 Linux machine  and I have done that using command "yum install Xvfb"

Hello Shruthi

All it is telling you is you have to set environment variable DISPLAY=0


If you xfvb listens to a different tcp port, change the value of DISPLAY accordingly,

You must be able to run chrome.  when you are everything else will work.


Thanks,

Let me know if you need further assistance


You can also look how my Vagrantbox for the same is configured on my github
https://github.com/sergueik/selenium_vagrant

or how a standalone shell command
e.g.
https://github.com/sergueik/selenium_java/blob/master/utils/node.sh

export HUB_IP_ADDRESS=127.0.0.1 export HUB_PORT=4444 export SELENIUM_JAR_VERSION=2.47.1 export DISPLAY_PORT=0 export ROLE=node ... export DISPLAY=:$DISPLAY_PORT # TODO : specify geometry of the display Xvfb $DISPLAY -ac >/dev/null 2>&1 & ... java $LAUNCHER_OPTS \ -classpath \ $SELENIUM_HOME/log4j-1.2.17.jar:$SELENIUM_HOME/selenium-server-standalone.jar: \ -Dlog4j.configuration=node.log4j.properties \ org.openqa.grid.selenium.GridLauncher \ -role node \ -host $NODE_HOST \ -port $NODE_PORT \ -hub http://${HUB_IP_ADDRESS}:${HUB_PORT}/hub/register \ -nodeConfig $CONFIG_FILE \ -browserTimeout 12000 -timeout 12000 \ -ensureCleanSession true \ -trustAllSSLCertificates This command is for node, you may adjust the argument for standalone Thanks

[shruthi v v]

Thanks for reply but how to check xfvb listens to which TCP port?

Hello Shuthi

You can check running processes and find the arguments xvfb is running with
there DISPLAY value is also written to /var/log/.xvfb
 - you need to see on your system (I do not have a vm with xvfb / selenium running locally so can't test this part directly atm.
