Adding Cucumber to JUnit project

If you want to add Cucumber to JUnit project, you need to do few things:

Add this dependency to pom.xml

<dependency>
        <groupId>com.cognifide.qa.bb</groupId>
        <artifactId>bb-cumber</artifactId>
        <version>${bb.version}</version>
</dependency>

Create Cucumber Injector

create CucumberInjectorSource.java

import com.google.inject.Guice;
import com.google.inject.Injector;
import cucumber.api.guice.CucumberModules;
import cucumber.runtime.java.guice.InjectorSource;

public class CucumberInjectorSource implements InjectorSource {

	@Override
	public Injector getInjector() {
		return Guice.createInjector(CucumberModules.SCENARIO, new GuiceModule());
	}

}

create cucumber-guice.properties under src/test/resources with fully qualified name of your CucumberInjectorSource

guice.injector-source=<your-package>.CucumberInjectorSource

Create Hooks

create package 'hooks' under src/main/java/com.cognifide
create TakeScreenshot.java in hooks package

import com.google.inject.Inject;
import cucumber.api.Scenario;
import cucumber.api.java.After;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;

/**
 * A helper class that can create a screenshot file.
 */
public class TakeScreenshot {
	/**
	 * Inject a WebDriver instance, because it will create the screenshot.
	 */
	@Inject
	private WebDriver webDriver;

	/**
	 * Creates the screenshot, embeds it in the scenario and closes webDriver.
	 */
	@After
	public void takeScreenshotAndClose(Scenario scenario) {
		if (scenario.isFailed() && webDriver instanceof TakesScreenshot) {
			byte[] screenshot = ((TakesScreenshot) webDriver).getScreenshotAs(OutputType.BYTES);
			scenario.embed(screenshot, "image/png");
		}
		webDriver.quit();
	}

}

create also WindowMaximize.java in hooks package

import com.google.inject.Inject;
import cucumber.api.java.Before;
import org.openqa.selenium.WebDriver;

/**
 * A helper class that will maximize window
 */
public class WindowMaximize {

	@Inject
	private WebDriver webDriver;

	@Before
	public void maximize() {
		webDriver.manage().window().maximize();
	}
}
