Selenium-Cucumber Pro

A VS Code extension that generates professional Selenium Java step definitions from Cucumber .feature files — instantly.

What It Does

2. Go to the Extensions panel (Ctrl+Shift+X)
3. Search for Selenium-Cucumber Pro
4. Click Install

Quick Start

1. Open a .feature file
2. Press Ctrl+Shift+G or click Cucumber Steps in the status bar
3. Choose Generate Step Definitions
4. Paste into your Java project

Commands

Right-click inside any .feature file for context menu access to all commands.

Configuration

Open Settings (Ctrl+,) and search for Cucumber, or use the Configure Settings action in the Quick Actions menu.

{
  "cucumberStepGen.packageName": "com.example.stepdefinitions",
  "cucumberStepGen.className": "StepDefinitions",
  "cucumberStepGen.baseTestClass": "BaseTest",
  "cucumberStepGen.framework": "cucumber",
  "cucumberStepGen.generateComments": true,
  "cucumberStepGen.generateTryCatch": true,
  "cucumberStepGen.methodNamingConvention": "camelCase"
}

Example

Input — feature file

Feature: Login
  Scenario: Successful login
    Given I am on the login page
    When I enter username "admin" and password "secret"
    Then I should see the dashboard

Output — generated Java

package com.example.stepdefinitions;

import io.cucumber.java.en.Given;
import io.cucumber.java.en.When;
import io.cucumber.java.en.Then;
import org.openqa.selenium.WebDriver;
import org.testng.Assert;

/**
 * Cucumber Step Definitions
 * Generated by Selenium-Cucumber Extension
 */
public class StepDefinitions {

    private WebDriver driver;

    @Given("^I am on the login page$")
    public void iAmOnTheLoginPage() {
        try {
            // TODO: driver.get("URL");
        } catch (Exception e) {
            throw new RuntimeException("Failed to execute step", e);
        }
    }

    @When("^I enter username \"(.*?)\" and password \"(.*?)\"$")
    public void iEnterUsernameAndPassword(String param1, String param2) {
        try {
            // TODO: implement login logic
        } catch (Exception e) {
            throw new RuntimeException("Failed to execute step", e);
        }
    }
}

Parameter Detection

The extension automatically detects and converts:

• "quoted strings" → "(.*?)" → String param
• <angle brackets> → (.*) → String tokenName
• 123 bare numbers → (\\d+) → int number
