Cucumber with Selenium WebDriver

Cucumber with Selenium

In this post, we will setup a Cucumber and Selenium WebDriver Project. We will automate the Google calculator feature using cucumber as a TDD framework and Selenium WebDriver for web UI automation. You can download the entire project(18kb only) here – Cucumber with Selenium Sample Project.

The structure of the maven project would be something like this-

Cucumber with selenium

Now we will refer to each file marked in the image one by one.

POM File

A POM file describes all the dependencies required in the project. This project is created as a maven project so all you need to do is include the POM file and all the required dependencies/libraries will get downloaded from maven repositories.
The libraries used in this project are-

  • Selenium, JUnit, Cucumber-Java, and Cucumber-JUnit.
  • Pom.xml file content-
<project xmlns="http://maven.apache.org/POM/4.0.0"

Feature File

This file will define the scenario to be tested. In this example we will write a scenario to test the Google calculator. Feature file content-

Feature: Check addition in Google calculatorcontent
   In order to verify that Google calculator work correctly
   As a user of Google
   I should be able to get correct addition result
   Scenario: Addition
   Given I open Google
   When I enter "2+2" in search textbox
   Then I should get result as "4"


Step Definition File

This file implements the steps stated in feature file e.g. for the step “Given I open Google” the step definition file will have a function that will launch a browser and open Google as an implementation to this step.

package artOfTesting.test;
import java.util.concurrent.TimeUnit;
import org.junit.Assert;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.By;
import cucumber.api.java.After;
import cucumber.api.java.Before;
import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;
public class googleCalcStepDefinition {
	
	
	protected WebDriver driver;
	
	 @Before
	    public void setup() {
	        driver = new FirefoxDriver();
	}
		
	@Given("^I open google$")
	public void I_open_google() {
		//Set implicit wait of 10 seconds and launch google
		driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
		driver.get("https://www.google.co.in");
	}
	
	@When("^I enter \"([^\"]*)\" in search textbox$")
	public void I_enter_in_search_textbox(String additionTerms) {
		//Write term in google textbox
		WebElement googleTextBox = driver.findElement(By.id("gbqfq"));
		googleTextBox.sendKeys(additionTerms);
					
		//Click on searchButton
		WebElement searchButton = driver.findElement(By.id("gbqfb"));
		searchButton.click();
	}
	
	@Then("^I should get result as \"([^\"]*)\"$")
	public void I_should_get_correct_result(String expectedResult) {
		//Get result from calculator
		WebElement calculatorTextBox = driver.findElement(By.id("cwos"));
		String result = calculatorTextBox.getText();
				
		//Verify that result of 2+2 is 4
		Assert.assertEquals(result, expectedResult);
		
		driver.close();
	}
	
	 @After
	    public void closeBrowser() {
	        driver.quit();
	 }
}


JUnit Test Runner file

The JUnit Test runner file will be used to run the project as a maven test.

package artOfTesting;
import org.junit.runner.RunWith;
import cucumber.api.junit.Cucumber;
@RunWith(Cucumber.class)
public class googleCalcTest {
}

In order to run the project just right click on the JUnit test runner file and click on “Run As -> JUnit test”, you can also run the project by right-clicking on the project and clicking on “Run As -> Maven test”.

This completes our post, do let us know in case you face any issue on setting up your Cucumber with Selenium testing project.
