Can't read test results file

[mvi...@thoughtworks.com]

I am trying to use the maven-jmeter-plugin like so (simplified for post):

<dependency>
<groupId>com.lazerycode.jmeter</groupId>
<artifactId>jmeter-maven-plugin</artifactId>
<version>1.6.0</version>
</dependency>

...

<build>
<plugins>
<plugin>
<groupId>com.lazerycode.jmeter</groupId>
<artifactId>jmeter-maven-plugin</artifactId>
<executions>
<execution>
<id>jmeter-tests</id>
<phase>verify</phase>
<goals>
<goal>jmeter</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>

When I run Maven to execute my JMeter tests (via "mvn verify"), I get the following error:

[debug] JMeter is called with the following command line arguments: -n -t /Users/mike/Work/src/test/jmeter/project.jmx -l /Users/mike/Work/target/jmeter/results/project-120702.jtl -d /Users/mike/Work/target/jmeter

It seems to me that since this file is in "target", it should not be expected to exist prior to running maven. Is this a bug, or am I doing something wrong?

Thanks,

Hi,

It seems that JMeter does not execute correctly.

Did you try running with "-X"?

Also, there may be errors in the jmeter.log.

You can take a look at this example workspace that has a fully configured and running JMeter test with results analysis:

Cheers,

it seems that you try to use a class that JMeter itself does not provide, thus the "CannotResolveClassException".

Just add the appropriate dependency in the <plugin> section so that JMeter can find the kg.apc.jmeter.threads.SteppingThreadGroup

[mvi...@thoughtworks.com]

I must be missing something here...

So it seems that the SteppingThreadGroup is a part of the jmeter-plugins GoogleCode project at https://code.google.com/p/jmeter-plugins/wiki/SteppingThreadGroup . And though I see documentation at https://code.google.com/p/jmeter-plugins/wiki/PluginInstall on how to install the Plugins, it talks about installing the jar file into the lib/ext dir of my server...But not how to install the plugins via Maven.

Also, I have downloaded and successfully run the jmeter-maven-plugin-example from Github, but there aren't any examples (that I see) of adding plugins to the jmeter maven plugin in there.

Is there documentation on this somewhere that I'm missing?

Thanks.

Usually you would just add another dependency to your POM, but in this case
it looks like there is no maven package for jmeter-plugins. (it probably
doesn't help with the word plugin used in the names of both of these
projects).

You would need to create a mavenised package for jmeter-plugins and add the
dependency to your POM (see

Are there any plans to provide an official Maven version of the jmeter-plugins jar?

[Mark Collin]

No idea I'm afraid, you would have to ask the jmeter-plugins devs.

 

It looks like there is an issue raised in their bug tracker to add maven support (although it doesn't seem particularly well worded):

 

https://code.google.com/p/jmeter-plugins/issues/detail?id=158&colspec=ID%20Type%20Status%20Priority%20Summary

 

Short Link

 

This mailing list is for the jmeter maven plugin, which is a maven plugin to allow you to run JMeter through maven, not a series of useful additions to JMeter itself.

 

More info about this project is available here:

 

http://jmeter.lazerycode.com/

 

https://github.com/Ronnie76er/jmeter-maven-plugin

 

The names are very similar but the objective of the projects is very different.

My apologies. As you've noted, it's a bit confusing trying to keep the two straight in my head. I'll head over there and comment on the bug.

Thanks!

[Mark Collin]

Not a problem :)
