Framework with Selenium WebDriver, RestAssured, Page Factory Pattern, Docker, Kubernetes, and Cucumber

Creating a framework with Selenium WebDriver, RestAssured, Page Factory Pattern, Docker, Kubernetes, and Cucumber combines modern testing strategies with behavioral-driven development (BDD). Here’s a comprehensive guide to setting up this framework.

3. Framework Components

DriverFactory.java (WebDriver Setup)

package com.framework.base;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;

public class DriverFactory {
    private static ThreadLocal<WebDriver> driver = new ThreadLocal<>();

    public static WebDriver getDriver() {
        if (driver.get() == null) {
            ChromeOptions options = new ChromeOptions();
            options.addArguments("--headless", "--no-sandbox", "--disable-dev-shm-usage");
            System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
            driver.set(new ChromeDriver(options));
        }
        return driver.get();
    }

    public static void quitDriver() {
        if (driver.get() != null) {
            driver.get().quit();
            driver.remove();
        }
    }
}

Page Object: LoginPage.java

package com.framework.pages;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;

public class LoginPage {
    WebDriver driver;

    @FindBy(id = "username")
    WebElement usernameField;

    @FindBy(id = "password")
    WebElement passwordField;

    @FindBy(id = "loginButton")
    WebElement loginButton;

    public LoginPage(WebDriver driver) {
        this.driver = driver;
        PageFactory.initElements(driver, this);
    }

    public void login(String username, String password) {
        usernameField.sendKeys(username);
        passwordField.sendKeys(password);
        loginButton.click();
    }
}

Step Definitions

UISteps.java

package com.framework.steps;

import com.framework.base.DriverFactory;
import com.framework.pages.LoginPage;
import io.cucumber.java.en.Given;
import io.cucumber.java.en.When;
import io.cucumber.java.en.Then;

import static org.testng.Assert.assertTrue;

public class UISteps {
    LoginPage loginPage;

    @Given("the user is on the login page")
    public void navigateToLoginPage() {
        DriverFactory.getDriver().get("http://localhost:8080");
        loginPage = new LoginPage(DriverFactory.getDriver());
    }

    @When("the user enters username {string} and password {string}")
    public void enterCredentials(String username, String password) {
        loginPage.login(username, password);
    }

    @Then("the user should see the home page")
    public void verifyHomePage() {
        assertTrue(DriverFactory.getDriver().getTitle().contains("Home"));
    }
}

APISteps.java

package com.framework.steps;

import io.restassured.RestAssured;
import io.cucumber.java.en.Given;
import io.cucumber.java.en.When;
import io.cucumber.java.en.Then;

import static io.restassured.RestAssured.given;
import static org.hamcrest.Matchers.equalTo;

public class APISteps {

    @Given("the API base URI is set")
    public void setBaseURI() {
        RestAssured.baseURI = "http://localhost:8080/api";
    }

    @When("I send a GET request to {string}")
    public void sendGETRequest(String endpoint) {
        RestAssured.requestSpecification = given().basePath(endpoint);
    }

    @Then("the response should have status code {int}")
    public void validateStatusCode(int statusCode) {
        RestAssured.requestSpecification.get().then().statusCode(statusCode);
    }
}

Feature Files

login.feature

Feature: User Login

Scenario: Successful Login
    Given the user is on the login page
    When the user enters username "admin" and password "password"
    Then the user should see the home page

API.feature

Feature: API Testing

Scenario: Validate GET Request
    Given the API base URI is set
    When I send a GET request to "/resource"
    Then the response should have status code 200

Cucumber Test Runner

TestRunner.java

package com.framework.runners;

import io.cucumber.testng.AbstractTestNGCucumberTests;
import io.cucumber.testng.CucumberOptions;

@CucumberOptions(
    features = "src/test/resources/features",
    glue = "com.framework.steps",
    plugin = {"pretty", "html:target/cucumber-report.html"}
)
public class TestRunner extends AbstractTestNGCucumberTests {
}

5. Run Tests

• Use mvn test to run locally.
• Deploy on Kubernetes and execute tests with CI/CD.

This framework is flexible, modular, and ideal for teams leveraging UI and API testing.
