Running Cucumber tests directly from executable jar

I have a project with cucumber and maven also I am using the JUnit.

I am able to run and build my project successfully from Eclipse.

Now I want to run the test from command line in another system which does(should) not have eclipse or cucumber installed. I have an idea that we can create a JAR from jar we can run the tests by java cli commands.

Below are the combinations I am trying to run my tests from , also I am pasting the pom.xml and RunCukesTest.java file..

enter image description here

RunCukesTest.java

package se.stepDefinations;


import org.junit.runner.RunWith;

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class)
@CucumberOptions(features = "src/test/resource/features/Printing.feature:117", plugin = { "pretty",
        "html:target/cucumber-html-report" }, glue = { "se.stepDefinations" }, tags = {})
public class RunCukesTest {

    public static void main(String[] args) throws Exception {


    }
}
  • I have added JUNIT Jar in Class path.

I am generating jars in 2 ways,

1) Exporting JAR using - > Project ->Export -> JAR File Selecting MAIN Class in the last step as : RunCukesTest as I have defined main method here for the entry point(do we require this main method in this class???)

After the export , I am running below command ,

1.1 java -jar xyz.jar I get error : NoClassDef found : org/junit/runner/JUnitCore

So I ran it this way :

1.2 java -cp xyz.jar;junit-4.12.jar org.junit.runner.JUnitCore It said,

JUnit version 4.12
Time:0.001
OK(0 tests)

It still didnt work , So I appended the RunCukesTest file namespace at the last,
1.3 java -cp xyz.jar;junit-4.12.jar org.junit.runner.JUnitCore se.stepDefinations.RunCukesTest
It gave me error :Type cucumber.api.junit.Cucumber not present

2) So I gave up on the option for Export of jar and I am trying now to use the JAR from the maven Build. I selected the POM to run with Maven Build and it created 2 jars in the target folder ,

1 with name xyz-0.0.1-SNAPSHOT with 16kb another with 2nd with
xyz-0.0.1-SNAPSHOT-jar-with-dependencies with 33mb

1) I ran the bigger file with dependencies using 

java -jar xyz-0.0.1-SNAPSHOT-jar-with-dependencies.jar

It gave me message :

Got no path to feature directory

2) So I tried appending the namespace to RunCukesTest file,

java -jar xyz-0.0.1-SNAPSHOT-jar-with-dependencies.jar se.stepDefinations.RunCukesTest

I received an error : not a file or directory found

, as of course as the error says , it is trying to find a feature inside the target folder.

Again , I want to run the JAR independent of any such project file dependencies in any other computer like an executable.

Any help would be appreciated. Thanks.

I'd like to extend the accepted answer to support Gradle, since this might be helpful for someone.

Given this is your project's structure

  • .root
    • src/
      • main/
        • java/ --> Put your .java files here
          • CukesRunner.java --> This is your main file
        • resources
          • features/ --> Put your .feature files here

The build.gradle file should look like something like this:


    apply plugin: 'java'
    
    sourceSets {
        main {
            java {
                srcDirs = ['src/main/java']
            }
            resources {
                srcDirs = ['src/main/resources']
            }
        }
    }
    
    dependencies {
         // Include your dependencies here
         compile '...'
     }
    
    configurations {
        cucumberRuntime {
            extendsFrom compile
        }
    }
    
    jar {
        from {
            // Package all dependencies in the .jar
            configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
        }
        manifest {
            // Indicate the main class for the .jar file
            attributes 'Main-Class': 'CukesRunner'
        }
    }

Then you can customize your CukesRunner.java just like the accepted answer suggested, but making sure to call for the features you compressed together with your jar file:

public class CukesRunner {
    
    public static void main(String[] args) throws Throwable {
        final String[] arguments = new String[]{
                "--glue", "<my Java classes packages reference>",
                "classpath:features" // This will look for the classpath inside the jar file
        };
        cucumber.api.cli.Main.main(arguments);
    }

}

@SpringBootApplication
public class Application {

    public static void main(final String[] args) throws Throwable {
        // SpringApplication.run(TestApplication.class, args);
        JUnitCore.main(CucumberTest.class.getCanonicalName());
    }
