Serenity/JS WebdriverIO

@serenity-js/webdriverio module is a Screenplay Pattern-style adapter for WebdriverIO that will help you with testing Web and mobile apps.

Installation

To install this module, use an existing WebdriverIO project or generate a new one by running:

npm init wdio .

Install the below Serenity/JS modules in your WebdriverIO project directory:

npm install --save-dev @serenity-js/assertions @serenity-js/console-reporter @serenity-js/core @serenity-js/serenity-bdd @serenity-js/web @serenity-js/webdriverio

To learn more about Serenity/JS and how to use it on your project, follow the Serenity/JS Getting Started guide fpr WebdriverIO.

Usage with Cucumber.js

To use Serenity/JS WebdriverIO with Cucumber.js, install the following adapter:

npm install --save-dev @serenity-js/cucumber

Please note that Serenity/JS WebdriverIO / Cucumber integration supports both Serenity/JS reporting services and native Cucumber.js reporters.

Usage with Jasmine

To use Serenity/JS WebdriverIO with Jasmine, install the following adapter:

npm install --save-dev @serenity-js/jasmine

Usage with Mocha

To use Serenity/JS WebdriverIO with Mocha, install the following adapter:

npm install --save-dev @serenity-js/mocha

Configuring WebdriverIO

To integrate Serenity/JS with WebdriverIO, configure your wdio.conf.ts to specify framework: '@serenity-js/webdriverio'. You can configure Serenity/JS in the same file.

// wdio.conf.ts
import { WebdriverIOConfig } from '@serenity-js/webdriverio'

// Optional, import custom Actors if needed; More on this below.
import { Actors } from './serenity/Actors.ts'

export const config: WebdriverIOConfig = {
    
    // Tell WebdriverIO to use Serenity/JS framework
    framework: '@serenity-js/webdriverio',

    // Serenity/JS configuration
    serenity: {
        // Configure Serenity/JS to use an appropriate test runner adapter
        runner: 'cucumber',
        // runner: 'mocha',
        // runner: 'jasmine',

        // Optional, register custom Cast to configure your Serenity/JS actors
        actors: new Actors(`https://api.example.org`),
        
        // Register Serenity/JS reporting services, a.k.a. the "stage crew"
        crew: [
            '@serenity-js/console-reporter',
            '@serenity-js/serenity-bdd',
            [ '@serenity-js/core:ArtifactArchiver', { outputDirectory: 'target/site/serenity' } ],
            [ '@serenity-js/web:Photographer', { 
                strategy: 'TakePhotosOfFailures', // or: 'TakePhotosOfInteractions'
            } ],
        ]
    },

    // configure Cucumber runner
    cucumberOpts: {
        // see the Cucumber configuration options below
    },

    // or Jasmine runner
    jasmineOpts: {
        // see the Jasmine configuration options below
    },

    // or Mocha runner
    mochaOpts: {
        // see the Mocha configuration options below
    },

    specs: [
        // load Cucumber feature files
        './features/**/*.feature',
        // or Mocha/Jasmine spec files 
        // './spec/**/*.spec.ts',
    ],
    
    // add any additional native WebdriverIO reports
    // reporters: [
    //     'spec',
    // ],

    // ... other WebdriverIO-specific configuration   
}

Using custom Serenity/JS Actors

By default, Serenity/JS uses a default cast of actors where every actor can:

• BrowseTheWebWithWebdriverIO
• TakeNotes.usingAnEmptyNotepad()

If you're planning to implement scenarios where actors have additional abilities, you can replace this default setup with a custom Cast, like this one:

// serenity/Actors.ts
import { Actor, Cast, TakeNotes } from '@serenity-js/core'
import { CallAnApi } from '@serenity-js/rest'
import { BrowseTheWebWithWebdriverIO } from '@serenity-js/webdriverio'
import type { Browser } from 'webdriverio'

export class Actors implements Cast {

    // Inject custom parameters via constructor
    constructor(private readonly apiUrl: string) {
    }
    
    prepare(actor: Actor): Actor {
        // You can assign abilities based on actor name, env variables, and so on
        switch (actor.name) {
            
            case 'Apisitt':
                return actor.whoCan(
                    CallAnApi.at(this.apiUrl)
                )
                
            default:
                return actor.whoCan(
                    BrowseTheWebWithWebdriverIO.using(browser), // global WDIO browser
                    TakeNotes.usingAnEmptyNotepad(),
                )
        }

    }
}

Using Serenity/JS with WebdriverIO and Mocha

// specs/example.spec.ts
import { actorCalled } from '@serenity-js/core'
import { Ensure, equals } from '@serenity-js/assertions'
import { By, Navigate, PageElement, Text } from '@serenity-js/web'
import { BrowseTheWebWithWebdriverIO } from '@serenity-js/webdriverio'

// example Lean Page Object describing a widget we interact with in the test
class SerenityJSWebsite {
    static header = () =>
        PageElement.located(By.css('h1'))   // selector to identify the interactable element
            .describedAs('header')          // description to be used in reports
}

describe('Serenity/JS', () => {
    
    it('works with WebdriverIO and Mocha', async () => {
        // actorCalled(name) instantiates or retrieves an existing actor identified by name
        // Actors class configures the actors to use WebdriverIO 
        await actorCalled('Wendy')
            .attemptsTo(
                Navigate.to('https://serenity-js.org'),
                Ensure.that(
                    Text.of(SerenityJSWebsite.header()),
                    equals('Enable collaborative test automation at any scale!')
                ),
            )
    })
})
