Cucumber BDD Skill
When to Use
Use this skill when you need generates Cucumber BDD tests with Gherkin feature files and step definitions in Java, JavaScript, or Ruby. Use when user mentions "Cucumber", "Gherkin", "Feature/Scenario", "Given/When/Then", "BDD". Triggers on: "Cucumber", "Gherkin", "BDD", "Feature file", "Given/When/Then", "step...
Core Patterns
Feature File (Gherkin)
Feature: User Login
As a registered user
I want to log into the application
So that I can access my dashboard
Background:
Given I am on the login page
Scenario: Successful login
When I enter "user@test.com" in the email field
And I enter "password123" in the password field
And I click the login button
Then I should be redirected to the dashboard
And I should see "Welcome" on the page
Scenario: Invalid credentials
When I enter "wrong@test.com" in the email field
And I enter "wrongpass" in the password field
And I click the login button
Then I should see an error message "Invalid credentials"
Scenario Outline: Login with various users
When I enter "<email>" in the email field
And I enter "<password>" in the password field
And I click the login button
Then I should see "<result>"
Examples:
| email | password | result |
| admin@test.com | admin123 | Dashboard |
| user@test.com | password | Dashboard |
| bad@test.com | wrong | Error |
Step Definitions — Java
import io.cucumber.java.en.*;
import static org.junit.jupiter.api.Assertions.*;
public class LoginSteps {
private LoginPage loginPage;
private DashboardPage dashboardPage;
@Given("I am on the login page")
public void iAmOnTheLoginPage() {
loginPage = new LoginPage(driver);
loginPage.navigate();
}
@When("I enter {string} in the email field")
public void iEnterEmail(String email) {
loginPage.enterEmail(email);
}
@When("I enter {string} in the password field")
public void iEnterPassword(String password) {
loginPage.enterPassword(password);
}
@When("I click the login button")
public void iClickLogin() {
dashboardPage = loginPage.clickLogin();
}
@Then("I should be redirected to the dashboard")
public void iShouldBeOnDashboard() {
assertTrue(driver.getCurrentUrl().contains("/dashboard"));
}
@Then("I should see {string} on the page")
public void iShouldSeeText(String text) {
assertTrue(dashboardPage.getPageSource().contains(text));
}
}
Step Definitions — JavaScript
const { Given, When, Then } = require('@cucumber/cucumber');
const { expect } = require('chai');
Given('I am on the login page', async function() {
await this.page.goto('/login');
});
When('I enter {string} in the email field', async function(email) {
await this.page.fill('#email', email);
});
When('I click the login button', async function() {
await this.page.click('button[type="submit"]');
});
Then('I should see {string} on the page', async function(text) {
const content = await this.page.textContent('body');
expect(content).to.(text);
});
Hooks
import io.cucumber.java.*;
public class Hooks {
@Before
public void setUp(Scenario scenario) {
driver = new ChromeDriver();
}
@After
public void tearDown(Scenario scenario) {
if (scenario.isFailed()) {
byte[] screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES);
scenario.attach(screenshot, "image/png", "failure-screenshot");
}
driver.quit();
}
}

Anti-Patterns
| Bad | Good | Why |
|---|
| UI details in Gherkin | Business language | Readability |
| One step per line of code | Meaningful business steps | Abstraction |
| No Background for shared steps | Use Background | DRY |
| Imperative steps | Declarative steps | Maintainable |
