By using Cucumber, you can bridge the communication gap between developers, testers, and business stakeholders.
  • Test Automation Framework – Selenium is a popular open-source framework for web application automation. It provides a robust set of APIs to interact with web elements, perform actions, and validate results. By integrating Cucumber with Selenium, you can leverage Selenium’s capabilities for browser automation while harnessing Cucumber’s powerful test case organization and execution features.
  • Collaboration – Cucumber promotes collaboration within the development team. With Cucumber, testers, developers, and business analysts can work together to define and refine the behavior of the application. By involving stakeholders in writing and reviewing Gherkin scenarios, you can ensure that the tests accurately reflect the desired functionality.
  • Test Reporting and Documentation – Cucumber generates detailed and structured reports that provide insights into the test execution results. These reports highlight the status of each scenario, including passed, failed, or pending tests. Additionally, the Gherkin feature files serve as living documentation, capturing the intended behavior of the application and facilitating test case management.
  • Reusability and Maintainability – Cucumber promotes the use of step definitions, which are reusable blocks of code that map Gherkin steps to Selenium actions. This abstraction allows for easy maintenance and reusability of test code. By separating the test logic from the implementation details, you can create a modular and scalable test suite.

Using Cucumber with Selenium brings clarity, collaboration, reusability, maintainability, and comprehensive reporting to your automated testing efforts.

Writing Your First Cucumber Selenium Test

Open Eclipse and proceed to create a new Java project of your choosing, granting it any desired name.

  • Add Necessary Dependencies: In the project, include the following dependencies in the pom.xml file for the project:
  • Create a Feature File: Generate a new feature file in the src/test/resources directory, bearing the ‘.feature’ extension. This file should encompass the scenarios that necessitate testing.
  • Write a Scenario: Compose a scenario in Gherkin syntax within the feature file as shown below:

Feature: Google Search
    As a user
    I want to search for a term on Google
    So that I can find relevant information
    Scenario: Search for “cucumber selenium”
        Given I am on the Google search page
        When I enter “cucumber selenium” in the search box
        And I click the search button
        Then I should see search results related to “cucumber selenium”

  • Write Step Definitions: In the project, create a new package called stepdefinitions under the src/test/java folder. In this package, create a new Java class called GoogleSearchSteps. In this class, write the step definitions for the scenario you just wrote. For example:
package stepdefinitions;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import io.cucumber.java.en.Given;
import io.cucumber.java.en.Then;
import io.cucumber.java.en.When;
public class GoogleSearchSteps {
    WebDriver driver;
    @Given("I am on the Google search page")
    public void iAmOnTheGoogleSearchPage() {
        System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
        driver = new ChromeDriver();
    @When("I enter {string} in the search box")
    public void iEnterInTheSearchBox(String searchTerm) {
    @When("I click the search button")
    public void iClickTheSearchButton() {
    @Then("I should see search results related to {string}")
    public void iShouldSeeSearchResultsRelatedTo(String searchTerm) {
        String pageTitle = driver.getTitle();
  • Run the Test: Once you are done writing the feature file and step definitions, you can proceed to execute the test. In Eclipse, right-click on the feature file and choose “Run As” > “Cucumber Feature” from the context menu. The test will be initiated, and you will be able to view the corresponding output in the console.

Automation Testing Using Cucumber with Selenium

Automation Testing Using Cucumber with Selenium

Once you have the prerequisites set up, you can start automating your tests using Cucumber with Selenium. Here is a step-by-step process to guide you through the automation testing journey:

  • Define Test Scenarios
    Begin by identifying the test scenarios you want to automate. These scenarios should represent specific functionalities or user interactions within your application. It is essential to have a clear understanding of the behavior you want to validate through automation.
  • Create Feature Files
    Test cases are written in Cucumber using the Gherkin human-readable format, which uses keywords like “Given,” “When,” and “Then” to define the test steps. Create feature files that represent your test scenarios, and describe them using Gherkin syntax. Feature files provide a structured approach to documenting and organizing your test cases.
  • Implement Step Definitions
    Code snippets known as step definitions are utilized to map Gherkin steps to the actual automation code. Every Gherkin step in the feature file should possess a corresponding step definition that outlines the actions to execute. These step definitions employ Selenium WebDriver methods to interact with web elements, carry out actions, and verify the anticipated outcomes.
  • Execute Tests
    You can now execute the tests by placing your feature files and step definitions. The Cucumber framework offers multiple options for test execution, including running tests from the command line, utilizing test runners, or integrating with build automation tools. During test execution, Cucumber reads the feature files, matches the steps with their corresponding step definitions, and runs the automation code.
  • Analyze Test Results
    After test execution, it is essential to analyze the test results. Cucumber provides built-in reporting mechanisms that generate detailed reports, including information about the passed and failed scenarios, along with any error messages or stack traces. These reports help you identify issues and track the progress of your automation efforts.
  • Maintain and Enhance Tests
    Cucumber automation tests require maintenance to keep up with application changes and evolving requirements. As your application evolves, update your feature files and step definitions to reflect the changes. Regularly review and enhance your test suite to cover new functionalities and ensure comprehensive test coverage.

By following these steps, you can effectively automate your tests using a combination of Cucumber and Selenium. This powerful combination enables seamless collaboration between technical and non-technical team members, enhances test readability, and establishes a robust framework for automation testing.

Examples of Cucumber Selenium

Below we will discuss some Selenium Cucumber examples :

Example 1: Implementing a Basic Test Case

In this scenario, we will show you how to actively implement a basic test case using Cucumber Selenium. The test case aims to validate the functionality of a specific feature or behavior of the application being tested.

Firstly, we utilize Gherkin syntax to generate a feature file. Gherkin serves as a user-friendly language, enabling us to specify the intended functionality of the application in a structured manner. We articulate the feature, present a scenario, and outline the required steps to validate the scenario.

Next, we write step definitions in Java to map the steps described in the feature file to Selenium WebDriver actions. Step definitions are methods that encapsulate the code needed to execute each step. For example, if the feature file states, “Given the user is on the login page,” the corresponding step definition will navigate the WebDriver to the login page URL.

After placing the feature file and step definitions, we can execute the test. Cucumber Selenium reads the feature file, matches the steps with their respective step definitions, and uses WebDriver to perform the necessary actions. We can run the test using Cucumber’s test runner either through an IDE or through the command line.

After performing the test, we should validate the results by comparing the actual behavior of the application with the expected behavior using cucumber’s JUnit or TestNG assertions libaries. If the actual behavior aligns with the expected behavior, the test will pass; otherwise, it will fail, indicating a deviation from the desired functionality.

Example 2: Data-Driven Testing with Cucumber and Selenium

Data-driven testing is a powerful technique that allows us to test multiple scenarios with different input data and expected outcomes. Cucumber Selenium provides support for data-driven testing through scenario outlines and examples tables.

In this scenario, we will examine the process of conducting data-driven testing using Cucumber Selenium. First, we define a scenario outline in the feature file, which serves as a blueprint for numerous test cases. We designate scenario outline placeholders to represent the diverse input data.

We then provide examples in an examples table below the scenario outline. Each row in the examples table represents a unique set of test data for a test case. We can define multiple columns to represent different data inputs, such as usernames and passwords.

When Cucumber Selenium executes the test, it substitutes the scenario outline placeholders with the corresponding values from the examples table. This allows us to automatically generate and execute multiple test cases with different data sets.

By parameterizing the test data, we can achieve extensive test coverage without duplicating test code. We can also easily add or modify test cases by simply adding or updating rows in the examples table. This flexibility and efficiency make data-driven testing an essential technique for comprehensive testing.

Example 3: Behavior-Driven Development (BDD) with Cucumber and Selenium

Behavior-Driven Development (BDD) promotes collaboration among stakeholders, developers, and testers by emphasizing the definition and testing of the expected behavior of the system under test.

Cucumber Selenium is an ideal framework for implementing BDD practices. In this scenario, we will learn how to write feature files that capture the expected behavior of the application. Feature files are written using Gherkin syntax, and they describe the features or functionalities to be tested.

Each feature file contains one or more scenarios that represent specific test cases. Scenarios are written using Given-When-Then steps, which describe the preconditions, actions, and expected outcomes of the test. These steps are then mapped to corresponding step definitions that interact with the application using Selenium WebDriver.

By following the BDD approach, we can ensure that the tests align with the desired behavior of the application and provide a clear understanding of the functionality being tested. BDD promotes collaboration by enabling stakeholders to participate in the creation and review of feature files. It also enhances test readability and maintainability, as the Gherkin syntax focuses on business-readable descriptions.

Using Cucumber Selenium for BDD enables teams to bridge the gap between business requirements and technical implementation, resulting in more effective and efficient testing. It also facilitates communication and understanding among team members, leading to higher-quality software and improved customer satisfaction.
