+# -------------- CodeIgniter Testing (4/20/2011) -------------- #
+
+
+# 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*
+
+# 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]
+
+
+## 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.
+
+
+### CodeIgniterTestCase Documentation
+
+
+Test cases should extend CodeIgniterTestCase. 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.
+
+$this->ci_instance($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.
+
+$this->ci_set_instance_var($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.
+
+
+## 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)

+# CodeIgniter Unit Tests #
+
+*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.symfony-project.com
+
+	# 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)

Subject: Fixed int typecasting of limit parameter in DB_active_rec.php

If an empty string was passed, the typecast was changing it to 0. This
produced "LIMIT 0" which returned no results. This must be a bug and not
a feature because there are other params after limit in both
$this->db->limit and $this->db->get.

Need to have the Wincache PHP module downloaded from http://www.iis.net/download/wincacheforphp.

Subject: Bumped CodeIgniter's PHP requirement to 5.2.4. Yes I know PHP 5.4
 just came out, and yes I know PHP 5.3 has lovely features, but there are
 plenty of corporate systems running on CodeIgniter and PHP 5.3 still is not
 widely supported enough. CodeIgniter is great for distributed applications,
 and this is the highest we can reasonably go without breaking support. PHP
 5.3 will most likely happen in another year or so. Fingers crossed on that
 one anyway...

Subject: Fix test errors in Loader_test.php and URI_test.php

Change exceptions from Exception to RuntimeException since PHPUnit 3.6
doesn't like you to expect generic exceptions. The error it gives is:

InvalidArgumentException: You must not expect the generic exception class
travis-ci.org/#!/tiyowan/CodeIgniter/builds/832518

This issue addressed by using exceptions that are more specific.

 -  Fixed a bug in the :doc:`Session Library <libraries/sessions>` where a PHP E_NOTICE error was triggered by _unserialize() due to results from databases such as MSSQL and Oracle being space-padded on the right.
 -  Fixed a bug (#501) - set_rules() to check if the request method is not 'POST' before aborting, instead of depending on count($_POST) in the :doc:`Form Validation Library <libraries/form_validation>`.
 -  Fixed a bug (#940) - csrf_verify() used to set the CSRF cookie while processing a POST request with no actual POST data, which resulted in validating a request that should be considered invalid.
+-  Fixed a bug in PostgreSQL's escape_str() where it didn't properly escape LIKE wild characters.
