Re: [testng-users] Re: Cannot load listeners when using testNG through Maven/surefire

[Cédric Beust ♔]

This is fixed in TestNG 6.8.5 (note that I haven't updated the Eclipse plug-in yet).

Hi, all!

 

I faced the same problem using maven failsafe plugin. I execute 'maven integration-test' in Eclipse. If I add listener in suite xml file (like testng.xml) then it works, but if I specify Listener in pom (using <property>), I get:

I use TestNG 6.8.1, Maven 2.2.1 and Eclipse Helios Service Release 2.

 

Thank you.

Greetings!

We are trying to integrate our testNG environment with maven and the surefire plugin and we are facing a problem when trying to use private listeners.

Here is a part of the pom.xml:

<plugins>

 <plugin>

  <groupId>org.apache.maven.plugins</groupId>

        <artifactId>maven-surefire-plugin</artifactId>

        <version>2.14.1</version>

        <configuration>

         <properties>

            <property>

              <name>usedefaultlisteners</name>

              <value>false</value> 

            </property>

            <property>

              <name>listener</name>

              <value>listeners.MyRetryListener,listeners.MySuiteListener,org.testng.reporters.XMLReporter,org.uncommons.reportng.HTMLReporter</value>

            </property>

          </properties>

          <suiteXmlFiles>

            <suiteXmlFile>src/com/sen/suites/login/MyXML.xml</suiteXmlFile>

               </suiteXmlFiles>

    </configuration>

  </plugin>

  </plugins>

Trying to run surefire:test target will result in the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.14.1:test (default-cli) on project suites: Execution default-cli of goal org.apache.maven.plugins:maven-surefire-plugin:2.14.1:test failed: There was an error in the forked process

The listeners we are trying to use are in a jar file that is already added in the classpath (no dependency errors seem to exist). This setup works without maven integration (like running the same config through command line). It is also successful when the listeners are removed.

 

Has anybody any idea on how to overcome this? Has anybody else encountered similar problems? Perhaps it is more like a surefire error but I would be grateful if I had a second opinion.

Thank you in advance!

I know, that It's an old issue, but I faced the same problem recently. I mean the same as in the previous message. I hope my message would be helpful for someone else searching the answer via google.

The problem is not in TestNG, but in maven-surefire-plugin. And It's the other problem than described in the first message of the topic.

The solution is to put all your listeners at the same line in pom.xml. You should use comma as a separator, no any line breaks.

It's the implementation of maven-surefire-plugin. It parses the value of the property with the following code: String[] classNames = listenerClasses.split( " *, *" );

So, fix your pom.xml like that:

<value>org.uncommons.reportng.HTMLReporter,org.uncommons.reportng.JUnitXMLReporter</value>

[Kangs]

To add to Kirill's information, if you have the habit of auto formatting using Eclipse Ctrl+Shift+F (or  Shift+Command+F), go to Eclipse --> Preferences --> XML --> XML Files --> Editor --> Line Width --> Change the default value 72 to higher value like 160.

This will prevent the comma separated value to be automatically indented to the next line.
