E2E 测试未在 Jenkins 作业上运行

Question

I have installed locally two Docker containers which include Jenkins and Selenium. I have a Maven project written in Java where I created a suite of E2E (End To End) tests realised using Selenium. From the terminal of IntelliJ, using "mvn test" (or mvn clean test or other combinations) command, the tests are running even if I use headless or not for Chrome Driver. Also, this is one of the plugins written in POM:

<plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-surefire-plugin</artifactId>
          <version>${maven-surefire-plugin.version}</version>
          <configuration>
            <forkCount>3</forkCount>
            <reuseForks>true</reuseForks>
            <argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
            <suiteXmlFiles>
              <suiteXmlFile>testng_suiteTest.xml</suiteXmlFile>
            </suiteXmlFiles>
          </configuration>
        </plugin>

The XML suite file contains the classes and the methods of each automated test.

The problem appears on Jenkins. So, I have created on Jenkins a job based on my Maven project where I set up the following goal and options after many tries (just to check if the result will become the wished one) for the Build section:

clean install test -DsuiteXmlFile=testngSuite.xml -Dwebdriver.chrome.driver=/var/jenkins_home/tools/chromedriver/chromedriver -Dselenium.browser=chrome -Dwebdriver.chrome.whitelistedIps=172.17.0.2

The fork-count was configured above because of the following error when the jenkins job was built:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test (default-test) on project : 
Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test failed: 
The forked VM terminated without saying properly goodbye. VM crash or System.exit called ? -> [Help 1]

After that, I have also installed those libraries at the root of the Jenkins container, due to the errors that appeared in the maven surefire report:

1. libglib2.0-0 (using the indications from Maythux: https://askubuntu.com/questions/58664/cant-install-package-libglib2-0-dev-because-it-depends-on-some-unknown-version )
2. libnss3 (simply using: root@04f87025a7fb:/# apt-get install libnss3 )

I have also interfered with: cannot assign requested address (99), but now is ok after reading and applying this: How to fix "[SEVERE]: bind() failed: Cannot assign requested address (99)" while starting chromedriver

After all of this operations and maybe others that it is possible to forgot writing here, now it seems to be a communication error between Jenkins and the Chrome Web Driver (or anything else) from which I ask for your help for suggestions. My last report after running a job says:

Also read and used those until now (that maybe will be useful for others in this situation):

Maven BUILD SUCCESSFUL but no tests executed in Selenium

The Failsafe Plugin is designed to run integration tests while the Surefire Plugin is designed to run unit tests.

TestNG does not continue execute tests after failure

configfailurepolicy="continue" 


  <properties>
    <java.version>1.8</java.version>
    <org.mapstruct.version>1.4.1.Final</org.mapstruct.version>

    <maven.compiler.source>1.7</maven.compiler.source>
    <maven.compiler.target>1.7</maven.compiler.target>
  </properties>

I have also used the Maven Failsafe plugin, but unfortunately nothing changed. TestNG version 7.0.0 used now.

So, I want to run my end to end tests on Jenkins with a job build in, any advice will be helpful!

Answer 1

The communication issue was solved installing locally on the VM of the Jenkins:

• manually installed: Chromium (being a Linux machine) and
• ChromeDriver plugin, also installed manually from the command line, since the plugin from the Jenkins interface was a lower version, which was not compatible with the last version of Chromium (91...)
