I'm using vstest to execute tests on local.
"C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe\" "C:\Debug\Solution.dll /Tests:VerifyTest1,VerifyTest2 /Logger:trx"
And over console i receive output something like this -
Passed VerifyTest1
Failed VerifyTest2
Standard Output Messages:

Now, i don't want the debug trace with all the info when a test fails on Console. I just want passed or failed result on Console. Is there a way to do that. I know that i can see the result on trx file but i just wanted to know is there a way to suppress the debug trace or Standard Output Messages on Console.
You May Want to Disable your trace Logs. You can do it thru multiple channels. Try as mentioned in here based on ur VSTS & .Net version. https://msdn.microsoft.com/en-us/library/jj159363(v=vs.120).aspx
0 is the setting for disabling traces.
Using MSTest instead of VSTest solved the purpose of my problem.

I am currently trying to set up a Selenium node on a Linux VM (headless). The hub is being run from a Windows device on port 5786 (4444 was in use).
I initiate the hub using the following code:
java -jar selenium-server-standalone-
2.53.0.jar -role node –hub http://<myIP>:5786/grid/register -port 5558
When i execute this, it returns the following error messages:

In the command that you shared viz.,
java -jar selenium-server-standalone-2.53.0.jar -role node –hub http://<myIP>:5786/grid/register -port 5558
You have a copy paste problem. The - before the parameter hub doesn't seem to be a hyphen character.
I was able to deduce this as a possible root cause because the value of -hub is completely being ignored and the default hub port of 4444 is being attempted to use. The stacktrace that you shared re-iterates this
13:42:13.435 WARN - error getting the parameters from the hub. The node may
end up with wrong timeouts.Connect to 10.146.48.80:4444 [/10.146.48.80]
failed: Connection refused
As you can see, even though you are providing your Hub's registration URL to include a port number of 5786, its still picking up 4444 and complaining Connection refused.
Please try typing out the entire command for starting the hub and try again. That should work.

Any help would be greatly appreciated.
This is most likely due to your window manager, bspwm. If you set the following environment variable before starting IntelliJ, it should work.
_JAVA_AWT_WM_NONREPARENTING=1
As #thomas pointed out, the missing environment variable is causing this issue
Here're the steps to do that.
Copy this -> _JAVA_AWT_WM_NONREPARENTING=1
If you have nano installed:
Run sudo nano /etc/environment on terminal and enter the password if prompted
Scroll to the bottom
Paste by pressing Shift + Insert
Save by pressing Ctrl + O and confirm the path with Enter
Quit by pressing Ctrl + X
If you have vim installed:
Run sudo vim /etc/environment on terminal and enter the password if prompted
Scroll to the bottom
Enter insert mode by pressing i
Paste by pressing Shift + Insert
Exit the insert mode by pressing Esc
Save and exit by typing :wq and Enter
The error should be resolved. This is apparently documented along with Android Studio on the wiki
This is regarding Selenium Automation Testing. I have a Jenkins job setup for some test executions.Jenkins is setup on a Ubuntu machine without GUI (CLI Only).
So when I run the scripts seems like it can't find the web browser obviously.
This job is working perfectly fine in windows. In Windows I get like this result.

Please provide me some technical specialities regarding this matter. Can I run this job in linux ? Please help me out
Well for unix systems you have to use Xvfb to run tests in headless mode, for jenkins you can use xvfb plugin
Simple example how to open firefox in headless mode
from xvfbwrapper import Xvfb
from selenium import webdriver
xf = Xvfb() # xf = Xvfb(1920, 1080) - will create virtual display with 1920x1080 size
xf.start()
# browser won't appear
driver = webdriver.Firefox()
driver.get("http://google.com")
I have a small Rexster/Titan cluster using Cassandra. A Rexster extension is used to query the graph. I did some benchmarking and did start and stop Rexster/Titan many times. But now I run into a strange issue: Rexster refuses to start but does not display any error message.
I tried to figure out what is causing this and reduced the cluster to a single node 192.168.0.4.
If I remove my extension Rexster manages to start up.
# console output
Forking Cassandra...
Running `nodetool statusthrift`..... OK
(returned exit status 0 and printed string "running").
Forking Titan + Rexster...
Connecting to Titan + Rexster (127.0.0.1:8184)...... OK
(connected to 127.0.0.1:8184).
Run rexster-console.sh to connect.
but when I place my extension uber JAR in the ext folder Rexster refuses to start.
# console output

Running `nodetool statusthrift`..... OK

See /var/lib/titan/bin/../log/rexstitan.log for Rexster log output.
If I now check rexstitan.log, as suggested by the console output, I can not find any error message.

My exception uses the logger for debugging. You can see the instantiation an usage on github: https://github.com/sebschlicht/titan-graphity-kribble/blob/master/src/main/java/de/uniko/sebschlicht/titan/extensions/GraphityExtension.java#L22
Though Rexster failed to start there is a process with the PID displayed in the console but curl fails to connect to Rexster:
$ curl 192.168.0.4:8182
curl: (7) Failed to connect to 192.168.0.4 port 8182: Connection refused
Why doesn't Rexster throw an exception? How can I debug this situation?
edit:
I removed any log messages in my code. I removed all exceptions that may be thrown during startup. Still Rexster refuses to start with my extension and the only hint in the log files is the unidentified read marker. I have to clue what prevents Rexster from starting.
The log message is nothing to worry about.
After rebuilding the application in another project step-by-step Rexster is now able to start with the extension. During this rebuild I noticed two situations, that can cause the behaviour described:
Missing dependency
If your project depends on a second project you might use Maven to inject it as a dependency. However, if you use
mvn clean package
to build the extension's JAR file it does not contain this dependency by default. You need to use a Maven plugin (e.g. maven-shade-plugin) to create a shaded JAR that contains all the dependencies your extension needs. Set the dependency scope to provided for all Titan/Rexster/Blueprints related dependencies. Use the shaded uber-JAR to deploy the extension to Rexster.
However, this was not new to me and should not have caused the problem in my case. There might be more situations that cause this problem or maybe there was a problem with Maven that messed up the shaded JAR. Feel free to browse the commit on github to catch this voodoo.
Missing extension
Another cause of this behaviour is a missing extension.
If you specify an extension in the com.tinkerpop.rexster.extension.RexsterExtension resource file, that is not present on startup, Rexster does neither log nor throw an exception, but refuses to start.
