A platform independent debuggable BDD Javascript testing framework. It's simple, easy to use and not dependant to any other tool or library. It's built with nodeJs, webdriver.io (the Selenium 2.0 bindings for NodeJS) and cucumber-js complete with integrated API Testing.

# To run your test locally, you'll need a local selenium server running, you can install and
# launch a selenium standalone server with chrome, firefox and phantomjs drivers via the 
# following commands in a separate terminal:

npm install selenium-standalone@latest -g --save-dev
selenium-standalone install
selenium-standalone start

# run 'npm install' in a terminal window from within the project folder
node ./node_modules/klassi-cucumber-js/index.js -s ./step-definitions
or
node index.js -d -t @search

By default tests are run using Google Chrome, to run tests using another browser supply the name of that browser along with the -b switch. Available options are:

A feature file is a Business Readable, Domain Specific Language file that lets you describe software’s behaviour without detailing how that behaviour is implemented. Feature files are written using the Gherkin syntax and must live in a folder named features within the root of your project.

duckDuckGo-search.feature

Feature: Searching for apps with duckduckgo
  As an internet user
  In order to find out more about certain user apps
  I want to be able to search for information about the required apps

  Background:
    Given The user arrives on the duckduckgo search page

  Scenario Outline: User inputs some search data
    When they input <searchword>
    Then they should see some results

    Examples:
      |searchword |
      |britian's got talent |
      |angry birds          |

The browser automatically closes after each scenario to ensure the next scenario uses a fresh browser environment.

Step definitions act as the glue between features files and the actual system under test.

To avoid confusion always return a JavaScript promise after your step definition in order to let cucumber know when your task has completed.

// ./step-definitions/duckDuckGo-search-steps.js

  Then(/^they should see some results$/, function() {
     /** return the promise of an element to the following then */
     return page.duckDuckGoSearch.searchResult();
  });

The following variables are available within the Given(), When() and Then() functions:

Page objects are accessible via a global page object and are automatically loaded from ./page-objects (or the path specified using the -p switch). Page objects are exposed via a camel-cased version of their filename, for example ./page-objects/duckDuckGoSearch.js becomes page.duckDuckGoSearch.

Page objects also have access to the same runtime variables available to step definitions.

An example page object:

// ./page-objects/duckDuckGoSearch.js

module.exports = {

  /** test searching for inputted data
   */
  url: 'https://duckduckgo.com/',
    
  /** enters a search term into duckduckgo search box and presses enter
   * @param {string} searchWord
   * @returns {Promise} a promise to enter the search values
   */
  performSearch: async function (searchWord) {
    let selector = shared.searchData.elem.searchInput;
    await driver.click(selector).keys(searchWord);
      
    let title = await driver.getTitle(selector);
    log.info('this is the page title:- ' + title);
      
    await driver.click(shared.searchData.elem.searchBtn);
    log.info('Search function completed');
  },
};

And its usage within a step definition:

// ./step-definitions/duckDuckGo-search-steps.js

  Given(/^The user arrives on the duckduckgo search page$/, function() {
     return helpers.loadPage(shared.searchData.url, 10);
  });
      
  When(/^they input (.*)$/, function(searchWord) {
     return page.duckDuckGoSearch.performSearch(searchWord);
  });

Automatic visual regression testing, gives the ability to take and save fullpage screenshots or of specific parts of the application / page under test.

You will need to have GraphicsMagick preinstalled on your system because WebdriverCSS uses it for image processing. To install GraphicsMagick follow the instructions here .

// ./runtime/helpers.js

cssImages: async function(pageName){
  await driver.webdrivercss(pageName, {
    name: '',
    elem: ''
  })
}

And its usage within a step definition:

  Then(/^they should see some results$/, async function() {
    /** return the promise of an element to the following then */
    await page.duckDuckGoSearch.searchResult();
     /** Take an image of the page under test */
    await helpers.cssImages('search');
  });

Getting data from a JSON REST API

// ./runtime/helpers.js
 getAPI: function (endpoint) {
    let endPoint = (endpoint);
    
    let options = {
        method: 'GET',
        url: endPoint,
        json: true,
        simple: false,
        resolveWithFullResponse: true,
    };
    
    return request(options)
    .then(function (response, err) {
        if (err) {
           // API call failed
        }
        // API call is successful
    });
 },

Shared objects allow you to share anything from test data to helper methods throughout your project via a global shared object. Shared objects are automatically loaded from ./shared-objects (or the path specified using the -o switch) and made available via a camel-cased version of their filename, for example ./shared-objects/test-data.js becomes shared.testData.

Shared objects also have access to the same runtime variables available to step definitions.

An example shared object:

// ./shared-objects/test-data.js

module.exports = {
  username: "import-test-user",
  password: "import-test-pa**word"
}

And its usage within a step definition:

  Given(/^I am logged in"$/, function () {
    driver.setValue('usn', shared.testData.username);
    driver.setValue('pass', shared.testData.password);
  });

HTML and JSON reports are automatically generated and stored in the default ./reports folder. This location can be changed by providing a new path using the -r command line switch:

You can register event handlers for the following events within the cucumber lifecycle.

const {After, Before, AfterAll, BeforeAll} = require('cucumber');

Most webdriverio methods return a JavaScript Promise that is resolved when the method completes. The easiest way to step in with a debugger is to add a .then method to a selenium function and place a debugger statement within it, for example:

  When(/^I search DuckDuckGo for "([^"]*)"$/, function (searchQuery, done) {
    driver.element('#search_form_input_homepage').then(function(input) {
      expect(input).to.exist;
      debugger; // <<- your IDE should step in at this point, with the browser open
      return input;
    })
    .then(function(input){
       input.setValue(selector, searchQuery);
       input.setValue(selector, 'Enter');

       done(); // <<- let cucumber know you're done
    });
  });

You can use the framework without any command line arguments if your application uses the following folder structure:

.
├── features
│   └── duckDuckGo-search.feature
├── step_definitions
│   └── duckDuckGo-search-steps.js
├── page-objects
│   └── duckDuckGoSearch.js
└── shared-objects
│   ├── test-data.js
│   └── stuff.json
└── reports
    ├── cucumber-report.json
    └── cucumber-report.html

Please raise bugs via the klassi-cucumber-js issue tracker and, if possible, please provide enough information to allow the bug to be reproduced.

Anyone can contribute to this project simply by opening an issue here or fork the project and issue a pull request with suggested improvements. In lieu of a formal styleguide, please take care to maintain the existing coding style.

klassi-cucumber-js was forked from John Doherty's, selenium-cucumber-js and as of December 2016 it has been completely independent of the that project. Since the fork many changes and improvements have been made, most notably the complete switch from selenium webdriver to webdriverio but still using the open development model without breaking the utilities operation.
