    # features/documentation.feature
Feature: Example feature
  As a user of Cucumber.js
  I want to have documentation on Cucumber
  So that I can concentrate on building awesome applications

  Scenario: Reading documentation
    Given I am on the Cucumber.js GitHub repository
    When I click on "CLI"
    Then I should see "Running specific features"
    // features/support/world.js
require('chromedriver')
var seleniumWebdriver = require('selenium-webdriver');
var {defineSupportCode} = require('cucumber');

function CustomWorld() {
  this.driver = new seleniumWebdriver.Builder()
    .forBrowser('chrome')
    .build();
}

defineSupportCode(function({setWorldConstructor}) {
  setWorldConstructor(CustomWorld)
})
    // features/step_definitions/hooks.js
var {defineSupportCode} = require('cucumber');

defineSupportCode(function({After}) {
  After(function() {
    return this.driver.quit();
  });
});
    // features/step_definitions/browser_steps.js
var seleniumWebdriver = require('selenium-webdriver');
var {defineSupportCode} = require('cucumber');

defineSupportCode(function({Given, When, Then}) {
  Given('I am on the Cucumber.js GitHub repository', function() {
    return this.driver.get('https://github.com/cucumber/cucumber-js/tree/master');
  });

  When('I click on {stringInDoubleQuotes}', function (text) {
    return this.driver.findElement({linkText: text}).then(function(element) {
      return element.click();
    });
  });

  Then('I should see {stringInDoubleQuotes}', function (text) {
    var xpath = "//*[contains(text(),'" + text + "')]";
    var condition = seleniumWebdriver.until.elementLocated({xpath: xpath});
    return this.driver.wait(condition, 5000);
  });
});

  • Run ./node_modules/.bin/cucumber-js
