<?php
/*
SimpleTest + CodeIgniter

test.php

the test runner - loads all needed files, integrates with CodeIgniter and runs the tests 

Written by Jamie Rumbelow
http://jamierumbelow.net/

Modifications by Nathan Fisher
http://junctionbox.ca/

Notes on Directory structure; where ./ is the root of a fresh CI project.

./test.php
./system/test # symlink or similar to root of SimpleTest folder
./system/application/tests
./system/application/tests/models
./system/application/tests/views
./system/application/tests/controllers

Changes:

  * Added console writer for test suite.
  * Moved all of the file scanning into classes.
  * Fixed a bug where vim swp files are treated as test classes.
  * Fixed a bug where view files can never exclusively be processed.

Todo:

  * Unit Tests - how ironic :(
  * Fix potential problem if test folders do not exist.

Free to use however you please... if it causes harm in anyway the authors are not liable.
