-Open Software License ("OSL") v 3.0
-###################################
-
-This Open Software License (the "License") applies to any original work of
-authorship (the "Original Work") whose owner (the "Licensor") has placed the
-following licensing notice adjacent to the copyright notice for the Original
-Work:
-
-*Licensed under the Open Software License version 3.0*
-
-
-*****************************
-1) Grant of Copyright License
-*****************************
-
-Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
-license, for the duration of the copyright, to do the following:
-
-	*a)* to reproduce the Original Work in copies, either alone or as part of
-	a collective work;
-
-	*b)* to translate, adapt, alter, transform, modify, or arrange the
-	Original Work, thereby creating derivative works ("Derivative Works")
-	based upon the Original Work;
-
-	*c)* to distribute or communicate copies of the Original Work and
-	Derivative Works to the public, *with the proviso that copies of Original
-	Work or Derivative Works that You distribute or communicate shall be
-	licensed under this Open Software License*;
-
-	*d)* to perform the Original Work publicly; and
-
-	*e)* to display the Original Work publicly.
-
-
-**************************
-2) Grant of Patent License
-**************************
-
-Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
-license, under patent claims owned or controlled by the Licensor that are
-embodied in the Original Work as furnished by the Licensor, for the duration
-of the patents, to make, use, sell, offer for sale, have made, and import the
-Original Work and Derivative Works.
-
-
-*******************************
-3) Grant of Source Code License
-*******************************
-
-The term "Source Code" means the preferred form of the Original Work for
-making modifications to it and all available documentation describing how to
-modify the Original Work. Licensor agrees to provide a machine-readable copy
-of the Source Code of the Original Work along with each copy of the Original
-Work that Licensor distributes. Licensor reserves the right to satisfy this
-obligation by placing a machine-readable copy of the Source Code in an
-information repository reasonably calculated to permit inexpensive and
-convenient access by You for as long as Licensor continues to distribute the
-Original Work.
-
-
-********************************
-4) Exclusions From License Grant
-********************************
-
-Neither the names of Licensor, nor the names of any contributors to the
-Original Work, nor any of their trademarks or service marks, may be used to
-endorse or promote products derived from this Original Work without express
-prior permission of the Licensor. Except as expressly stated herein, nothing
-in this License grants any license to Licensor's trademarks, copyrights,
-patents, trade secrets or any other intellectual property. No patent license
-is granted to make, use, sell, offer for sale, have made, or import
-embodiments of any patent claims other than the licensed claims defined in
-Section 2) No license is granted to the trademarks of Licensor even if such
-marks are included in the Original Work. Nothing in this License shall be
-interpreted to prohibit Licensor from licensing under terms different from
-this License any Original Work that Licensor otherwise would have a right to
-license.
-
-
-**********************
-5) External Deployment
-**********************
-
-The term "External Deployment" means the use, distribution, or communication
-of the Original Work or Derivative Works in any way such that the Original
-Work or Derivative Works may be used by anyone other than You, whether those
-works are distributed or communicated to those persons or made available as an
-application intended for use over a network. As an express condition for the
-grants of license hereunder, You must treat any External Deployment by You of
-the Original Work or a Derivative Work as a distribution under section 1(c).
-
-
-*********************
-6) Attribution Rights
-*********************
-
-You must retain, in the Source Code of any Derivative Works that You create,
-all copyright, patent, or trademark notices from the Source Code of the
-Original Work, as well as any notices of licensing and any descriptive text
-identified therein as an "Attribution Notice." You must cause the Source Code
-for any Derivative Works that You create to carry a prominent Attribution
-Notice reasonably calculated to inform recipients that You have modified the
-Original Work.
-
-
-****************************************************
-7) Warranty of Provenance and Disclaimer of Warranty
-****************************************************
-
-Licensor warrants that the copyright in and to the Original Work and the
-patent rights granted herein by Licensor are owned by the Licensor or are
-sublicensed to You under the terms of this License with the permission of the
-contributor(s) of those copyrights and patent rights. Except as expressly
-stated in the immediately preceding sentence, the Original Work is provided
-under this License on an "AS IS" BASIS and WITHOUT WARRANTY, either express or
-implied, including, without limitation, the warranties of non-infringement,
-merchantability or fitness for a particular purpose. THE ENTIRE RISK AS TO THE
-QUALITY OF THE ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY
-constitutes an essential part of this License. No license to the Original Work
-is granted by this License except under this disclaimer.
-
-
-**************************
-8) Limitation of Liability
-**************************
-
-Under no circumstances and under no legal theory, whether in tort (including
-negligence), contract, or otherwise, shall the Licensor be liable to anyone
-for any indirect, special, incidental, or consequential damages of any
-character arising as a result of this License or the use of the Original Work
-including, without limitation, damages for loss of goodwill, work stoppage,
-computer failure or malfunction, or any and all other commercial damages or
-losses. This limitation of liability shall not apply to the extent applicable
-law prohibits such limitation.
-
-
-*****************************
-9) Acceptance and Termination
-*****************************
-
-If, at any time, You expressly assented to this License, that assent indicates
-your clear and irrevocable acceptance of this License and all of its terms and
-conditions. If You distribute or communicate copies of the Original Work or a
-Derivative Work, You must make a reasonable effort under the circumstances to
-obtain the express assent of recipients to the terms of this License. This
-License conditions your rights to undertake the activities listed in Section
-1, including your right to create Derivative Works based upon the Original
-Work, and doing so without honoring these terms and conditions is prohibited
-by copyright law and international treaty. Nothing in this License is intended
-to affect copyright exceptions and limitations (including "fair use" or "fair
-dealing"). This License shall terminate immediately and You may no longer
-exercise any of the rights granted to You by this License upon your failure to
-honor the conditions in Section 1(c).
-
-
-*********************************
-10) Termination for Patent Action
-*********************************
-
-This License shall terminate automatically and You may no longer exercise any
-of the rights granted to You by this License as of the date You commence an
-action, including a cross-claim or counterclaim, against Licensor or any
-licensee alleging that the Original Work infringes a patent. This termination
-provision shall not apply for an action alleging patent infringement by
-combinations of the Original Work with other software or hardware.
-
-
-*****************************************
-11) Jurisdiction, Venue and Governing Law
-*****************************************
-
-Any action or suit relating to this License may be brought only in the courts
-of a jurisdiction wherein the Licensor resides or in which Licensor conducts
-its primary business, and under the laws of that jurisdiction excluding its
-conflict-of-law provisions. The application of the United Nations Convention
-on Contracts for the International Sale of Goods is expressly excluded. Any
-use of the Original Work outside the scope of this License or after its
-termination shall be subject to the requirements and penalties of copyright or
-patent law in the appropriate jurisdiction. This section shall survive the
-termination of this License.
-
-
-*******************
-12) Attorneys' Fees
-*******************
-
-In any action to enforce the terms of this License or seeking damages relating
-thereto, the prevailing party shall be entitled to recover its costs and
-expenses, including, without limitation, reasonable attorneys' fees and costs
-incurred in connection with such action, including any appeal of such action.
-This section shall survive the termination of this License.
-
-
-*****************
-13) Miscellaneous
-*****************
-
-If any provision of this License is held to be unenforceable, such provision
-shall be reformed only to the extent necessary to make it enforceable.
-
-
-***************************************
-14) Definition of "You" in This License
-***************************************
-
-"You" throughout this License, whether in upper or lower case, means an
-individual or a legal entity exercising rights under, and complying with all
-of the terms of, this License. For legal entities, "You" includes any entity
-that controls, is controlled by, or is under common control with you. For
-purposes of this definition, "control" means (i) the power, direct or
-indirect, to cause the direction or management of such entity, whether by
-contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the
-outstanding shares, or (iii) beneficial ownership of such entity.
-
-
-****************
-15) Right to Use
-****************
-
-You may use the Original Work in all ways not otherwise restricted or
-conditioned by this License or by law, and Licensor promises not to interfere
-with or be responsible for such uses by You.
-
-
-********************************
-16) Modification of This License
-********************************
-
-This License is Copyright © 2005 Lawrence Rosen. Permission is granted to
-copy, distribute, or communicate this License without modification. Nothing in
-this License permits You to modify this License as applied to the Original
-Work or to Derivative Works. However, You may modify the text of this License
-and copy, distribute or communicate your modified version (the "Modified
-License") and apply it to other original works of authorship subject to the
-following conditions: (i) You may not indicate in any way that your Modified
-License is the "Open Software License" or "OSL" and you may not use those
-names in the name of your Modified License; (ii) You must replace the notice
-specified in the first paragraph above with the notice "Licensed under <insert
-your license name here>" or with a notice of your own that is not confusingly
-similar to the notice in this License; and (iii) You may not claim that your
-original works are open source software unless your Modified License has been
-approved by Open Source Initiative (OSI) and You comply with its license
-review and certification process.

+### Introduction:
+
+This is the preliminary CodeIgniter testing documentation. It
+will cover both internal as well as external APIs and the reasoning
+behind their implemenation, where appropriate. As with all CodeIgniter
+documentation, this file should maintain a mostly human readable
+format to facilitate clean api design. [see http://arrenbrecht.ch/testing/]
+
+*First public draft: everything is subject to change*
+
+### Requirements
+
+PHP Unit >= 3.5.6
+
+	pear channel-discover pear.phpunit.de
+	pear install phpunit/PHPUnit
+
+vfsStream
+
+	pear channel-discover pear.php-tools.net
+	pear install pat/vfsStream-alpha
+
+#### Installation of PEAR and PHPUnit on Ubuntu
+
+  Installation on Ubuntu requires a few steps. Depending on your setup you may
+  need to use 'sudo' to install these. Mileage may vary but these steps are a
+  good start.
+
+	# Install the PEAR package
+	sudo apt-get install php-pear
+
+	# Add a few sources to PEAR
+	pear channel-discover pear.phpunit.de
+	pear channel-discover pear.symfony-project.com
+	pear channel-discover components.ez.no
+	pear channel-discover pear.php-tools.net 
+
+	# Finally install PHPUnit and vfsStream (including dependencies)
+	pear install --alldeps phpunit/PHPUnit
+	pear install --alldeps pat/vfsStream-alpha
+
+	# Finally, run 'phpunit' from within the ./tests directory
+	# and you should be on your way!
+
+## Test Suites:
+
+CodeIgniter bootstraps a request very directly, with very flat class
+hierarchy. As a result, there is no main CodeIgniter class until the
+controller is instantiated.
+
+This has forced the core classes to be relatively decoupled, which is
+a good thing. However, it makes that portion of code relatively hard
+to test.
+
+Right now that means we'll probably have two core test suites, along
+with a base for application and package tests. That gives us:
+
+1. Bootstrap Test	- test common.php and sanity check codeigniter.php [in planning]
+2. System Test		- test core components in relative isolation [in development]
+3. Application Test	- bootstrapping for application/tests [not started]
+4. Package Test		- bootstrapping for <package>/tests [not started]
+
+### CI_TestCase Documentation
+
+Test cases should extend CI_TestCase. This internally extends
+PHPUnit\_Framework\_TestCase, so you have access to all of your
+usual PHPUnit methods.
+
+We need to provide a simple way to modify the globals and the
+common function output. We also need to be able to mock up
+the super object as we please.
+
+Current API is *not stable*. Names and implementations will change.
+
+    $this->ci_set_config($key, $val)
+
+Set the global config variables. If key is an array, it will
+replace the entire config array. They are _not_ merged.
+
+    $this->ci_instance($obj)
+
+Set the object to use as the "super object", in a lot
+of cases this will be a simple stdClass with the attributes
+you need it to have. If no parameter, will return the instance.
+
+	$this->ci_instance_var($name, $val)
+
+Add an attribute to the super object. This is useful if you
+set up a simple instance in setUp and then need to add different
+class mockups to your super object.
+
+	$this->ci_core_class($name)
+
+Get the _class name_ of a core class, so that you can instantiate
+it. The variable is returned by reference and is tied to the correct
+$GLOBALS key. For example:
+    
+	$cfg =& $this->ci_core_class('cfg'); // returns 'CI_Config'
+    $cfg = new $cfg; // instantiates config and overwrites the CFG global
+
+	$this->ci_set_core_class($name, $obj)
+	
+An alternative way to set one of the core globals.
+
+	$this->ci_get_config()  __internal__
+	
+Returns the global config array. Internal as you shouldn't need to
+call this (you're setting it, after all). Used internally to make
+CI's get_config() work.
+
+	CI_TestCase::instance()  __internal__
+
+Returns an instance of the current test case. We force phpunit to
+run with backup-globals enabled, so this will always be the instance
+of the currently running test class.
+
+### Going forward
+
+#### 1. Bootstrap Test
+
+Testing common.php should be pretty simple. Include the file, and test the
+functions. May require some tweaking so that we can grab the statics from all
+methods (see is_loaded()). Testing the actual CodeIgniter.php file will most
+likely be an output test for the default view, with some object checking after
+the file runs. Needs consideration.
+
+#### 2. System Test
+
+Testing the core system relies on being able to isolate the core components
+as much as possible. A few of them access other core classes as globals. These
+should be mocked up and easy to manipulate.
+
+All functions in common.php should be a minimal implementation, or and mapped
+to a method in the test's parent class to gives us full control of their output.
+
+#### 3. Application Test:
+
+Not sure yet, needs to handle:
+
+- Libraries
+- Helpers
+- Models
+- MY_* files
+- Controllers (uh...?)
+- Views? (watir, selenium, cucumber?)
+- Database Testing
+
+#### 4. Package Test:
+
+I don't have a clue how this will work.
+
+Needs to be able to handle packages
+that are used multiple times within the application (i.e. EE/Pyro modules)
+as well as packages that are used by multiple applications (library distributions)
