Utility configuration and functions for Cucumber and WebdriverIO that can be used when writing acceptance test for web applications.

This project is a port of the Cucumber Boilerplate developed by Christian Broman to the NPM package and aims to create a easily reusable setup.

Features

• Super simple setup
• Full integration with WebdriverIO
• Over 150 predefined steps that cover almost everything you need, you can start writing tests right away
• Easy integration with cloud services like Sauce Labs
• Integration of WebdriverIO's Multiremote functionality
• Easy to run tests in parallel

How to write a test

Tests are written in Gherkin syntax that means that you write down what's supposed to happen in a real language. All test files are located in ./test/features/* and have the file ending .feature. You will already find some test files in that directory. They should demonstrate, how tests could look like. Just create a new file and write your first test.

myFirstTest.feature

Feature:
    In order to keep my product stable
    As a developer or product manager
    I want to make sure that everything works as expected

Scenario: Check title of website after search
    Given I open the url "http://google.com"
    When I set "WebdriverIO" to the inputfield "#gbqfq"
    And I press "Enter"
    Then I expect that the title is "WebdriverIO - Google Search"

Scenario: Another test
    Given ...

This test opens the browser and navigates them to google.com to check if the title contains the search query after doing a search. As you can see, it is pretty simple and understandable for everyone.

How to run the test

Create wdio.conf.js and import the wdio config from the NPM package:

import { config } from 'wdio-cucumber-utilities/lib/config';

export config;

Now run wdio and it will run any features that are present in the test/features/ directory.

Configurations

To configure your tests, checkout the config.js file in your test directory. It comes with a bunch of documented options you can choose from.

Running single feature

Sometimes its usefull to only execute a single feature file, to do so use the following command:

$ wdio --spec ./test/features/select.feature

Using tags

If you want to run only specific tests you can mark your features with tags. These tags will be placed before each feature like so:

@Tag
Feature: ...

To run only the tests with specific tag(s) use the --tags= parameter like so:

$ wdio --tags=@Tag,@AnotherTag

You can add multiple tags separated by a comma

Pending test

If you have failing or unimplemented tests you can mark them as "Pending" so they will get skipped.

// skip whole feature file
@Pending
Feature: ...

// only skip a single scenario
@Pending
Scenario: ...

Adding new steps and snippets

wdio cucumber utitilies comes with a predefined set of utility functions. You can add or override utility functions by overriding or extending cucumberOpts.require and adding your own paths.

import { config } from 'wdio-cucumber-utilities/lib/config';

config.cucumberOpts.require = ['tests/steps/myOwnSteps.js'].concat(config.cucumberOpts.require);

export config;

You define your snippet using regular expressions. This is pretty powerful as it allows you to create complex sentences with multiple options. Everything that's within "([^"]*)?" gets captured and appended to the callback. The last argument is always a callback function that you need to call when your step is done. You can access the browser and your WebdriverIO instance with browser.

To assert values this boilerplate project comes with a Chai integration.

Comments

You can add additional descriptive comments in your feature files.

###
  This is a
  block comment
###
Feature: As a bystander
    I can watch bottles falling from a wall
    So that I can be mildly amused

# This is a single line comment
Scenario: check if username is present
    Given I login as "roboter" with password "test123"
    Then the username "roboter" should be present in the header
