Introduction

CLI tool for generating Cucumber Specs to run in a web browser

Installation

Build Status

npm  install -g cucumberjs-browser

Why?

There are a few examples out in the wild that demonstrate how to write CucumberJS specs in the browser and/or for the browser:

Good libraries and examples, but I wanted to be able to write my feature specs, support and step definitions as I normally would that are run under the CucumberJS CLI for node, and have them simply execute in the browser without having to modify them to fit another runtime or environment.

Additionally, I wanted to be able to define custom listeners that will provide feedback from your run specs dependent on my development needs and CI endpoint.

Further Reading

A few articles have been written with further details on incorporating into your project and test automation routines:

Note:

As of February 15th, 2014, there is only the following listeners that can be assigned:

  • TAP (using the node-tap module)
  • UI (basic example of printing specs to DOM)
  • SAUCELABS (uses QUnit reporting model to hook into saucelabs reporter)
  • TESTEM (patches Testem.emit to emulate like qunit adapter)

More to come...

How?

The cucumberjs-browser cli tool bundles feature specs, support files and step definitions into standalone browserify-ied modules.

These references are injected into a testrunner template which instantiated a new CucumberJS runtime when the testrunner is loaded in a browser. When a format listener is defined, the page and/or console are updated as specs are run.

All this is donw without having to change the way you write your specs as you normally do!

Usage

cucumberjs-browser [-o outdir] [-f format] [--tmpl template] [--features features]

outdir

The directory to generate the web-based cucumber task-runner.

Default: /browser-cukes

template

The default template to use in generating the main task-runner page. Most likely you will want to provide your own custom template that also loads your projects libraries and stylesheets. There is a default template that should be used as an example of what is required to properly run the specs in a browser.

Default: /template/cucumber-testrunner.template

features

The directory path for the Cucumber feature specs.

This location is used in globbing and bundling support and step files from the following locations under the directory:

  • /support/**/*.js
  • /step_definitions/**/*.js

Default: /features

format

The format to provide in the browser.

Formats are delivered by assigning a listener to the CucumberJS runtime in the browser. Currently, these listeners are internally to this library and are bundled and deployed to the specified output directory. In the future I would like to open up the possibility of assigning custom formatters/listeners.

Possible values (as of February 15th, 2014):

  • ui
  • tap
  • saucelabs
  • testem

Default: none
