Serenity/JS Cucumber

@serenity-js/cucumber integrates Serenity/JS with Cucumber, enabling you to run automated, plain-language scenarios with rich reporting and powerful Screenplay-based abstractions.

Features

• Integrates Serenity/JS with Cucumber.js
• Supports all Cucumber.js versions from 0.x to 12.x
• Enriches Serenity reports with Gherkin feature descriptions, scenarios, and steps
• Supports using Screenplay Pattern APIs in step definitions

Installation

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

See the Serenity/JS Installation Guide.

Quick Start

import { actorCalled, actorInTheSpotlight } from '@serenity-js/core';
import { Given, When, Then } from '@cucumber/cucumber';
import { Ensure, equals } from '@serenity-js/assertions';

Given('{word} has {int} apples', async (actorName: string, count: number) => {
    // Create or retrieve the actor by name
    await actorCalled(actorName).attemptsTo(
        // Add tasks or interactions
    );
});

When('she adds {int} apples', async (count: number) => {
    // Retrieve the most recently used actor
    await actorInTheSpotlight().attemptsTo(
        // Add tasks or interactions
    )
});

Then('she has {int} apples', async (expectedCount: number) => {
    await actorInTheSpotlight().attemptsTo(
        Ensure.that(/* actual count */, equals(expectedCount))
    )
})

Configuration

When using Serenity/JS with WebdriverIO, follow the official Serenity/JS WebdriverIO + Cucumber integration guide.

To use Serenity/JS with Cucumber and Playwright, follow the steps below, or use one of the available Serenity/JS Project Templates.

Configuring Cucumber.js

Use the cucumber.js configuration file to set up Cucumber to use Serenity/JS as the "formatter" and load extra *.config.ts files.

// cucumber.js
module.exports = {
    default: {
        // Use TypeScript in-memory transpiler, ts-node 
        // requires `npm install --save-dev ts-node`
        requireModule: ['ts-node/register'],

        // Use Serenity/JS Cucumber adapter
        format: ['@serenity-js/cucumber'],
        // Configure the adapter
        formatOptions: {
            specDirectory: 'features'
        },
        require: [
            // Load configuration files
            './features/**/*.config.ts',
            // Load step definition libraries
            './features/**/*.steps.ts'
        ],
    }
}

Configuring Serenity/JS

To configure Serenity/JS, create a serenity.config.ts file with the following content:

// features/support/serenity.config.ts
import { configure, Cast } from '@serenity-js/core'
import { BeforeAll } from '@cucumber/cucumber'

BeforeAll(async () => {

    // ... start any services or browsers here
    
    // Configure Serenity/JS
    configure({
        
        actors: Cast.where(actor => {
            return actor.whoCan(
                // ... add abilities here
            )
        }),
        
        crew: [
            [ '@serenity-js/console-reporter', { theme: 'auto' } ],
            // ... add other crew members here
        ]
    })
})
