+# CodeIgniter Unit Tests #
+
+Status : [![Build Status](https://secure.travis-ci.org/EllisLab/CodeIgniter.png?branch=feature/unit-tests)](http://travis-ci.org/EllisLab/CodeIgniter)
+
+*Do not merge to default until these issues have been addressed*
+
+- Clean up naming conventions
+- Figure out config stuff
+- Figure out database testing
+
+### 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)
