Integration of Selenium, Cucumber, and JUnit

  

To integrate Selenium, Cucumber, and JUnit, you can build a Behavior Driven Development (BDD) test framework that allows you to define test scenarios in Gherkin (plain English), implement those steps in Java (using Selenium for UI interactions), and execute them using JUnit.

Components Overview:

Component	Role
Selenium WebDriver	Automates browser actions
Cucumber	Provides BDD support via .feature files
JUnit	Executes the test suite (test runner)

Below are the steps to integrate Selenium, Cucumber and JUnit

1. Maven Dependencies

<dependencies>
    <!-- Selenium -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>4.19.1</version>
    </dependency>

    <!-- Cucumber -->
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-java</artifactId>
        <version>7.14.0</version>
    </dependency>
    <dependency>
        <groupId>io.cucumber</groupId>
        <artifactId>cucumber-junit</artifactId>
        <version>7.14.0</version>
        <scope>test</scope>
    </dependency>

    <!-- JUnit -->
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.13.2</version>
        <scope>test</scope>
    </dependency>
</dependencies>

2. Feature File 

Feature: Google Search Functionality

  Scenario: Search for a keyword on Google
    Given I open the Chrome browser
    When I open "https://www.google.com"
    And I search for "Cucumber BDD"
    Then I should see the results page

3. Step Definition file

package stepDefinitions;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import io.cucumber.java.en.*;

import static org.junit.Assert.*;

public class GoogleSearchSteps {
    WebDriver driver;

    @Given("I open the Chrome browser")
    public void i_open_the_chrome_browser() {
        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
        driver = new ChromeDriver();
    }

    @When("I open {string}")
    public void i_open(String url) {
        driver.get(url);
    }

    @When("I search for {string}")
    public void i_search_for(String query) {
        WebElement searchBox = driver.findElement(By.name("q"));
        searchBox.sendKeys(query);
        searchBox.submit();
    }

    @Then("I should see the results page")
    public void i_should_see_the_results_page() {
        assertTrue(driver.getTitle().toLowerCase().contains("cucumber bdd"));
        driver.quit();
    }
}

4. JUnit Test Runner

package runners;

import org.junit.runner.RunWith;
import io.cucumber.junit.Cucumber;
import io.cucumber.junit.CucumberOptions;

@RunWith(Cucumber.class)
@CucumberOptions(
    features = "src/test/resources/features",
    glue = {"stepDefinitions"},
    plugin = { "pretty", "html:target/cucumber-reports" },
    monochrome = true
)
public class TestRunner {
}

How to Run the Tests

Right-click on TestRunner.java > Run As > JUnit Test
or
Use the Maven command:

mvn test

 Output

• Browser opens Google

• Types the query and submits

• Assertion is done on the title

• Generates HTML report in: target/cucumber-reports/index.html
