Unable to execute tests in parallel using testng and maven surefire plugin - maven

Need your help as i have been struggling with parallel execution using maven. i am trying to run Testng tests in parallel, maven V3.3.9, maven-surefire-plugin V2.18.1, with the below configurations.
<suiteXmlFiles>
<suiteXmlFile>testng.xml</suiteXmlFile>
</suiteXmlFiles>
<parallel>classes</parallel>
<threadCount>10</threadCount>
and also tried <suitethreadpoolsize>10</suitethreadpoolsize>
But, tests aren't running in parallel. i have been searching extensively for two days but couldn't get it working. Tried all the suggestions available on google!! Need your inputs to find out where i might be wrong.

Tests run slower with Maven than with IDE

I'm facing some test time execution issue related to local test execution with Maven. I have around 250 tests which run about 15 min on the IDE test runner and about an hour (55min to be exact) when executing them with maven locally. I tried a lot of configurations to make test execution in parallel but neither of them work for me, the time is still the same...probably I'm doing something wrong. Can anyone help on this? The last maven surefire plugin configuration that I tried is the following:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<parallel>methods</parallel>
<threadCount>10</threadCount>
</configuration>
</plugin>
And for test execution command I've used:
mvn test
mvn surefire:test

why does my maven tests fails when run as a whole and passes when ran individually?

Hi I am having a strange scenario.
I have a spring boot java project . I have lots of Junit tests as well.
when i run the tests from the terminal by issuing the command mvn clean test, 2 tests belong to a class fails
however if run the those tests belonging to that class from the eclipse Run as >> Junit tests it passes .
any idea why does this happens ? and how can i fix it ?
the following is my sure fire plugin configuration
<maven-surefire-plugin.version>2.18.1</maven-surefire-plugin.version>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>${maven-surefire-plugin.version}</version>
<configuration>
<!-- Force alphabetical order to have a reproducible build -->
<runOrder>alphabetical</runOrder>
</configuration>
</plugin>
thank you

Maven skip specific test [duplicate]

In my maven project I have a number of modules. Is it possible to turn off running unit test for some modules via command line options?
My project takes about 15 mins to run through all unit tests. I would like to speed up the overall build by running just the unit tests in the module I am working on. I do not want to go in and edit each individual pom.xml to achieve this.
I have tried a solution outlined here: Can I run a specific testng test group via maven? However the result is a lot of test failures in modules that I want to skip. I suppose 'group' is not the same concept of module?
To toggle unit tests on and off for an entire project use Maven Surefire Plugin's capability of skipping tests. There is a drawback with using skipTests from the command line. In a multi-module build scenario, this would disable all tests across all modules.
If you need more fine grain control of running a subset of tests for a module, look into using the Maven Surefire Plugin's test inclusion and exclusion capabilities.
To allow for command-line overrides, make use of POM properties when configuring the Surefire Plugin. Take for example the following POM segment:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.9</version>
<configuration>
<excludes>
<exclude>${someModule.test.excludes}</exclude>
</excludes>
<includes>
<include>${someModule.test.includes}</include>
</includes>
</configuration>
</plugin>
</plugins>
</build>
<properties>
<someModule.skip.tests>false</someModule.skip.tests>
<skipTests>${someModule.skip.tests}</skipTests>
<someModule.test.includes>**/*Test.java</someModule.test.includes>
<someModule.test.excludes>**/*Test.java.bogus</someModule.test.excludes>
</properties>
With a POM like the above you can execute tests in a variety of ways.
Run all tests (the above configuration includes all **/*Test.java test source files)
mvn test
Skip all tests across all modules
mvn -DskipTests=true test
Skip all tests for a particular module
mvn -DsomeModule.skip.tests=true test
Only run certain tests for a particular module (this example includes all **/*IncludeTest.java test source files)
mvn -DsomeModule.test.includes="**/*IncludeTest.java" test
Exclude certain tests for a particular module (this example excludes all **/*ExcludeTest.java source files)
mvn -DsomeModule.test.excludes="**/*ExcludeTest.java" test
Found a way to exclude on command line:
# Exclude one test class, by using the explanation mark (!)
mvn test -Dtest=!LegacyTest
# Exclude one test method
mvn verify -Dtest=!LegacyTest#testFoo
# Exclude two test methods
mvn verify -Dtest=!LegacyTest#testFoo+testBar
# Exclude a package with a wildcard (*)
mvn test -Dtest=!com.mycompany.app.Legacy*
This is from: https://blog.jdriven.com/2017/10/run-one-or-exclude-one-test-with-maven/
…and if you like to pass the parameter to maven release plugin in Hudson/Jenkins you have to use
-Darguments=-DskipTests
to get it work.
If you want to use Maven profiles:
http://maven.apache.org/guides/introduction/introduction-to-profiles.html
you might want to make it work doing something like this:
Skipping tests in some modules in Maven
I don't know if there is a supported command line option that does the same.
You also might try using environment properties directly, something as per this doc page:
http://maven.apache.org/plugins/maven-surefire-plugin/examples/skipping-test.html
i.e. something like:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.12</version>
<configuration>
<skipTests>${moduleA.skipTests}</skipTests>
</configuration>
</plugin>
then using mvn -DmoduleA.skipTests=false test to test that one module.

Different log4j settings when running with Maven than when running from Eclipse

I'd like my console to be as quiet as possible when I run my tests with mvn test, unless something goes wrong. Then again, when I'm writing tests in Eclipse (in other words, when I run single junit tests inside Eclipse), it's ok for them to be pretty verbose.
So I would need a way to have different log4j/logback settings when running all my tests with surefire than when I run them one by one in Eclipse. Is there a way to accomplish this?
You can configure surefire to use a different logger settings file. That will be ignored by Eclipse.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<argLine>-Dlogback.configuration=[wherever]</argLine>
</configuration>
</plugin>

Start multiple selenium test cases using jenkins

I'm a newbie to using jenkins.
I'm using jenkins to build by maven project. After the build process I need to run around 5 selenium2 test cases. Each test case takes around 20 minutes to finish, if I run one test case after the other it takes around 100 minutes complete all the test cases.
I want to know if it is possible to start all the test cases at once so that I can save time.
Currently my pom.xml is as follows -
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<junitArtifactName>junit:junit</junitArtifactName>
<includes>
<include>**/*Test*.java</include>
</includes>
</configuration>
</plugin>
Please let me know on how I can do this?
The best way to run tests in parallel from Jenkins is Selenium Grid.
You can find info on the Grid here: http://selenium-grid.seleniumhq.org/
Jenkins plugin here: https://wiki.jenkins-ci.org/display/JENKINS/Selenium+Plugin
