jmeter.JMeter: Error in NonGUIDriver java.lang.NullPointerException #113

Thrilochana · 2015-01-28T11:06:55Z

I am trying to execute Jmeter websocket sampler (https://github.com/maciejzaleski/JMeter-WebSocketSampler) tests. I get the following error. Could anyone please help?

How are you running it?

Sounds like a duplicate of #97

Thrilochana · 2015-01-28T11:56:20Z

I am running from mvn(mvn verify). Tests are created using websocket sampler(this is a plugin), is this an issue?

Thrilochana · 2015-01-29T04:27:12Z

I checked the issue 97, but it sounded different than this. I am trying to run a sample Jmeter test file(jmx file) created using websocket sampler.

I created tests from HTTP sampler and ran, this works fine.

Having issues in running tests created by websocket sampler. Do we have to provide any parameters in the POM if we are using customized plugins for jmeter? Please suggest

here is the pom.xml

Ardesco · 2015-01-29T06:38:47Z

Yes you need to add them as a dependency for the plugin and then if you want them copied into the /lib/ext directory you need to specify this in your configuration.

Have a look at https://github.com/jmeter-maven-plugin/jmeter-maven-plugin/wiki/Adding%20Additional%20Libraries%20To%20The%20Classpath

jmeter-plugins used to have a transitive dependency issue that could affect you if you use maven 2, I don't know if they have fixed it yet or not.

Thrilochana · 2015-01-29T09:11:22Z

Jmeter plugins does not contain the websocket sampler plugin(https://github.com/maciejzaleski/JMeter-WebSocketSampler). What should we do in this case?

I have added websocket jmeter plugin and dependencies to target\jmeter\lib\ext

Ardesco · 2015-01-29T09:15:31Z

then you will need to specify the maven dependency for WebSocketSampler. Use the documentation above as an example of the information required, just replace jmeter plugins artefact information with WebSocketSampler artefact information

Thrilochana · 2015-01-29T11:10:13Z

Thank you so much Ardesco. I am able to run my tests

Ardesco · 2015-01-29T11:14:36Z

Excellent :)

rpagadala · 2015-12-11T23:47:19Z

Hi All,

Even though after I have added the kg.apc plugin and dependency in the pom.xml .still getting the NoNGUIDriver issue through the mvn

See the attached jmx file.I am using JMter Latest version 2.13.

Please read this again:

https://github.com/jmeter-maven-plugin/jmeter-maven-plugin/wiki/Adding%20Additional%20Libraries%20To%20The%20Classpath

You need to add the dependency to the plugin, you cant just add it as a general dependency in your POM. All the general dependencies you have added to your POM look to be redundant.

rpagadala · 2015-12-12T21:15:00Z

Hi Mark,

Exactly I did the same thing shows in the link which you have provided(2nd one).

I have attached the JMX file, Error file & POM file and also I have attached the bin & lib screenshots from the target folder which generates after mvn install

Please guide me where I am missing.

error.txt
JMXfile.txt
pom.txt
bin.pdf
lib-sc1.pdf

Thanks,
Rajani

afranken · 2015-12-12T23:05:30Z

Hi Rajani,
I'm afraid you did not follow the instructions.
Just as Mark wrote, you have to declare the dependency for the jmeter-maven-plugin, not in the dependencies element of the POM.
Look at the description again, please.
Cheers,
Arne

Hi Mark & Arne,

Even though POM configured correctly when I goggled it seems plug- in/mvn 2 issue. I saw your response in the following links.
http://stackoverflow.com/questions/32343437/error-in-nonguidriver-conversionexception-com-atlantbh-jmeter-plugins-jsonutils

#92

I couldn't find solution any where nor I even did not see any examples who have tried with the Stepping Thread Group .I don't know what else to do where to go.

I have tried the same JMX with normal Thread Group executed successfully, If I use Stepping Thread Group throws error. Error is specific to the Stepping Thread Group

rpagadala · 2015-12-14T01:45:26Z

Where Can I find the Stepping Thread Group Project Repository in the Githiub

rpagadala · 2015-12-14T18:40:52Z

When I looked at top of the error I see this

[WARNING] The POM for kg.apc:perfmon:jar:1.0.0 is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details

#92
And I have seen response from Ardesco "problem with the jmeter-plugins artifact "

There is no solution?
Could some one please guide me what to do next?

Thanks,
Rajani

afranken · 2015-12-14T20:42:32Z

To make sure that the solution is clear:
This is a usage problem which can be solved by following the plugin documentation:

Thanks to Mark, Frank & Ardesco!

I have realized where I did a mistake!
