cucumber-replicate

Run Cucumber scenarios Parallel on Multiple browsers. Replicates the feature files based on the Browsers user wants to run

Are you looking to run your Cucumber Scenarios on Multiple Browsers, and all in Parallel? You'r at the right place.

1. cucumber-replicate automatically replicates the Cucumber Feature files based on requested Browsers to run; i.e. you can request BROWSER=firefox,chrome,safari
2. You can use cucumber-parallel module to run them in parallel mode - Features/Scenarios in Parallel
3. Your Selenium WebDriver configuration will decide which browser to launch at the run time. Please read further how to setup your in your existing framework.

Setup

1. Install

   
   npm i cucumber-replicate --save-dev
   

1. It's a grunt task. You'd need to add below tasks to your grunt

Gruntfile.js

var replicateTask = require('cucumber-replicate').task;

module.exports = function(grunt) {

    ...
    ...
    ...
    
    var replicate = replicateTask({
        baseDir: path.join(process.cwd(), '/test/')
        grunt: grunt,
        key: 'SAUCE' //to run tests on SauceLabs
    });

    grunt.loadNpmTasks('grunt-force-task');

    // replicate features for the parallel run
    grunt.registerTask('replicate', replicate.features);

    // clean up replicated features
    grunt.registerTask('clean', replicate.clean);

    // exit from your cucumberjs task, e.g. taskk is cucumberjs:acceptance
    grunt.registerTask('exit', replicate.exit.fromTask('cucumberjs:acceptance'));

    // Acceptance - create your Final Task. Run your suite with grunt acceptance
    grunt.registerTask('acceptance', ['clean', 'replicate', 'force:cucumberjs',
        'force:clean', 'exit']);
};

1. Map the replicated feature files to your Browser setup as shown below

world.js

var replicate = require('cucumber-replicate').replicate;

function World() {

    var world = this;

    function setupTestBed(resolve, reject) {

        var options = {
            replicate: {
                baseDir: path.join(process.cwd(), '/test/')
            },
            map: {
                key: 'BROWSER', // this can be anything, i.e. SAUCE_BROWSER
                featurePath: world.scenario.getUri()
            }
        };

     
        function launchBrowser() {
            // your code to launch browser
            // Read process.env key as BROWSER to launch the respected browser
        }

        return replicate(options.replicate)
            .map(options.map) // maps the replicated folder structures to requested browser & sets the process.env variable, BROWSER in this case
            .then(launchBrowser)
            .catch(reject);
    }

    return new Promise(setupTestBed);
}

module.exports = function() {
    this.World = World;
};
