Configuring Cucumber JUnit

To get started with Cucumber, you need to add the required version of Cucumber JUnit to your project:

 <dependencies>
   [...]
     <dependency>
         <groupId>io.cucumber</groupId>
         <artifactId>cucumber-junit</artifactId>
         <version>${cucumber.version}</version>
         <scope>test</scope>
     </dependency>
   [...]
 </dependencies>

Then create an empty class that uses the Cucumber JUnit runner.

package org.sample.cucumber;

import org.junit.runner.RunWith;

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

@RunWith( Cucumber.class )
public class RunCucumberIT
{
  [...]
}

This will execute all scenarios in the package of the runner. By default a glue code is assumed to be in the same package. The @CucumberOptions annotation can be used to provide additional configuration of Cucumber.

Note that in this example the BDD scenarios are executed by the Failsafe Plugin in the integration-test phase of the build lifecycle. The Failsafe Plugin can be invoked by calling the verify phase.

mvn verify

Using JUnit Rules

The Cucumber supports JUnit annotations @ClassRule, @BeforeClass and @AfterClass. These are invoked around the suite of features. Using these is not recommended as it limits the portability between different runners. Instead it is recommended to use Cucumbers `Before` and `After` hooks to setup scaffolding.

Using other JUnit features

The Cucumber runner acts like a suite of a JUnit tests. As such other JUnit features such as Categories, Custom JUnit Listeners and Reporters and re-running failed tests can all be expected to work.
