Boilerplate project to run WebdriverIO tests with Cucumber and brings true BDD to JavaScript. Instead of writing complicated test code that only developers can understand, Cucumber maps an ordinary language to code and allows to start with the test process in the early stages of your product development.

• Node version 6 or higher

Although this project works fine with NPM we recommend to use Yarn (>= 0.20.0) instead, due to its speed & solid dependency locking mechanism. To keep things simple we use yarn in this guide, but feel free to replace this with NPM if that is what you are using.

Choose one of the following options:

1. Download the latest stable release here or clone the git repo — git clone https://github.com/webdriverio/cucumber-boilerplate.git

2. Then:

• Copy the files to your project into a directory like /integrationtests (note the hidden files!)

3. Clean the project (Optional):

• On OSX/Linux: -- Run yarn run clean

• On Windows: -- Remove the directories /.git, /.github, /demo-app & /test -- Remove the files .travis.yml, jest.json & wdio.BUILD.conf.js -- Remove all the demo features from the /src/features directory

4. Install the dependencies (yarn install)

Now you are ready to write your own 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

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 ./src/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.

Start the local web server:

$ yarn run local-webserver

To run your tests just call the WDIO runner:

$ yarn run wdio

please note The WDIO runner uses the configuration file wdio.conf.js by default.

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

You can setup multiple configs for specific environments. Let's say you want to have a different baseUrl for your local and pre-deploy tests. Use the wdio.conf.js to set all general configs (like mochaOpts) that don't change. They act as default values. For each different environment you can create a new config with the following name scheme:

wdio.<ENVIRONMENT>.conf.js

Now you can create a specific config for your pre-deploy tests:

wdio.STAGING.conf.js

var config = require('./wdio.conf.js').config;

config.baseUrl = 'http://staging.example.com'

exports.config = config;

Your environment-specific config file will get merged into the default config file and overwrites the values you set. To run a test in a specific environment just add the desired configuration file as the first parameter:

$ yarn run wdio wdio.STAGING.conf.js

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

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

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:

$ yarn run wdio -- --tags=@Tag,@AnotherTag

You can add multiple tags separated by a comma

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: ...

The predefined snippets allow you to do a lot of common things but you might need extra snippets which are better aligned with your aims. To do so you will find all step definitions in ./src/steps. They are separated in given, when and then.

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.

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

Check out all predefined snippets. You can see how they get used in sampleSnippets.feature.
