dalek-pluginize v1.0.1

dalek-pluginize

Enables the creation of Dalek plugins for assertions and actions by wrapping the Dalek test object.

About

The current version of Dalek (<= 1.0.0) does not support the creation of assertion or action plugins to extend the functionality that comes with the library. This shortcoming is already being addressed as part of the DalekJS API proposal for new upcoming version.

The purpose of this library is to temporarily fill in this gap until the new version of Dalek is installed to allow the writing of cleaner and chainable Dalek test code today.

Install

With npm do:

npm install dalek-pluginize --save

Usage

Registering an action/assertion:

var dalekPluginize = require('dalek-pluginize');

dalekPluginize.addAction('showDialog', function(){
  return this.click('.dialog');
});

// Namespace plugins similar to `.assert`
dalekPluginize.addAction('ns', 'open', function(path){
  return this.open('http://localhost:9000/' + path);
});

// Bulk register custom actions
dalekPluginize.addActions({
  showDialog: function() { },
  ...
});

Consuming custom actions/assertions:

var ex = require('dalek-pluginize').extend;

module.exports = {
  'My Dalek test': function(test) {
    ex(test)
      .ns.open('test/index.html')
      .showDialog()
      .assert.visible('.dialog')
      .done();
  }
}
