Can I create an executable TestNG Selenium jar with my tests using maven

    my testNG xml TestTest.xml

    <groups>
        <run>
          <include name="basic"/> 
        </run>      
    </groups>
    
    <classes>
      <class name="myproj.TestTest"/>
    </classes>
    

    my tests in TestTest.java
    package myproj;
    
    import org.testng.annotations.Test;
    
    public class TestTest{
        @Test(groups = { "basic" })
        public void Test05BasicPASS() {
            System.out.println("This is test 5, Basic Pass");
        }
    }
    

    precon, Maven 3.5.4 and Java 1.8 installed

    directory structure:
    -testproj
       pom.xml
       TestTest.xml
       -src
          -myproj
             TestTest.java
    
    Jars get output to:
    -testproj
      -target
    

    On command line I can run:

    mvn package -DskipTests=false
    

    to build, run tests and generate jars

    After running and the jar exists, I believe I should be able to run the following and have the tests run as well:

    java -jar %CD%\target\erstest-0.0.1-jar-with-dependencies.jar TestTest.xml 
    

    Net goal, to be able to build a project using testng and run my tests with testNG xmls on the command line.

    I have been able to copy dependencies and run the following:

    java -cp %CD%\target\*; org.testng.TestNG TestTest.xml
    

    but this is not as nice as just getting everything into one jar.

    If possible, I don't want to have to recreate the TestNG main and further pass xmls etc. I want to just use TestNG as is and package it with my tests in a single jar.

    This should work independent of any IDE.



  • If you want to build so callled "fat jar" - a single executable .jar containing all dependencies and invoking TestNG main class I would recommend going for Maven Shade Plugin:

    1. Remove the following lines from your pom.xml

      <scope>provided</scope>
      
    2. Add the following Maven Shade plugin definition to create an executable jar:

      <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-shade-plugin</artifactId>
          <version>3.2.1</version>
          <executions>
              <execution>
                  <phase>package</phase>
                  <goals>
                      <goal>shade</goal>
                  </goals>
                  <configuration>
                      <transformers>
                          <transformer
                                  implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                              <mainClass>org.testng.TestNG</mainClass>
                          </transformer>
                      </transformers>
                  </configuration>
              </execution>
          </executions>
      </plugin>
      
    3. Package the jar
    4. Once done you should be able to invoke your test as jar -jar myproj-0.0.1.jar
