Writing Your First Cucumber Test: A Step-by-Step Tutorial for Automation Testing with Cucumber Framework


Embarking on the journey of Automation Testing with the Cucumber framework can be both exciting and rewarding. In this step-by-step tutorial, we’ll guide you through the process of writing your first Cucumber test. Whether you’re a testing novice or looking to explore the capabilities of Cucumber, this tutorial is designed to provide clarity and simplicity.

Understanding the Basics:

Before diving into the practical aspects, let’s briefly revisit the basics. Cucumber is a testing framework that supports Behavior-Driven Development (BDD). BDD emphasizes collaboration between technical and non-technical stakeholders by expressing test scenarios in a natural language format called Gherkin.

Setting Up Your Environment:

Ensure your testing environment is ready for Cucumber. Start by installing Java, as Cucumber is Java-based. Choose an Integrated Development Environment (IDE) such as Eclipse or IntelliJ IDEA for a seamless coding experience. Integrate a build tool like Maven or Gradle to manage dependencies efficiently.

Installing Cucumber Dependencies:

Begin by creating a new Maven or Gradle project in your chosen IDE. Add the necessary Cucumber dependencies to your project configuration. These include Cucumber-Java for step definitions, Cucumber-Junit for integrating with JUnit, and Gherkin for interpreting Gherkin language.

Creating Your Feature File:

The heart of a Cucumber test lies in its feature file written in Gherkin syntax. This file outlines the behavior of the application in a natural language format. Start by creating a “features” directory in your project, and within it, add a new feature file with a “.feature” extension.

In this file, define your feature, scenarios, and steps using Gherkin language. For example:


Feature: Login Functionality


 Scenario: Successful Login

 Given the user navigates to the login page

 When the user enters valid credentials

 Then the user should be logged in successfully


Writing Step Definitions:

Translate the steps from your feature file into Java code by creating step definitions. These step definitions will interact with your application to execute the defined steps. Create a “stepDefinitions” package in your project and add a Java class to define the step implementations.

For example:



import io.cucumber.java.en.Given;

import io.cucumber.java.en.When;

import io.cucumber.java.en.Then;


public class StepDefinitions {


 @Given(“the user navigates to the login page”)

 public void navigateToLoginPage() {

 // Code to navigate to the login page



 @When(“the user enters valid credentials”)

 public void enterValidCredentials() {

 // Code to enter valid credentials



 @Then(“the user should be logged in successfully”)

public void verifySuccessfulLogin() {

 // Code to verify successful login




Running Your Cucumber Test:

With your feature file and step definitions in place, run your Cucumber test. Use the JUnit runner to execute the test. Observe the test results, and you should see the successful execution of your scenario.


Congratulations! You’ve successfully written and executed your first Cucumber test. This step-by-step tutorial has provided a foundational understanding of creating feature files, defining steps, and running Cucumber tests.
