Fatal error running unit test in Yii app - yii

Question

This Question is local to my situation and not resolved (yet). But if you are experiencing this problem, the trouble shooting steps may give you a good path to start on.
I want to run a unit test in a Yii web application on localhost, which is running via WampServer 2.1 on Windows 7.
<?php
class LittleTest extends CTestCase
{
public function testApprove()
{
$value1 = "1";
$this->assertEquals($value1,$value1);
}
}
?>
I receive a fatal error when I try to run the test. Here is how I run it, on the Windows command line:
C:\wamp\www\app\protected\tests>
C:\wamp\www\app\protected\tests>cd unit
C:\wamp\www\app\protected\tests\unit>phpunit LittleTest.php
I receive (along with some stack trace lines):
PHP Fatal error:
class 'CTestCase' not found in [path to file]\LittleTest.php on line 4
Trouble shooting steps to this point:
The app runs. The default index page of the app looks good and I have used the gii tool to create a model class.
From command line, I can see php and phpunit are available (and I've been over my pear install to make sure it's all good):
C:\wamp\www\app\protected\tests>
C:\wamp\www\app\protected\tests>phpunit --version
PHPUnit 3.7.13 by Sebastian Bergmann.
C:\wamp\www\app\protected\tests>
C:\wamp\www\app\protected\tests>php --version
PHP 5.3.5 (cli)
... etc
display_errors is turned on. display_startup_errors is turned on.
I tried renaming the class so that name did not match the document name:
class LittleTestTweak extends CTestCase
I'm not sure of the precise command that runs the test, so I have tried variants like:
php LittleTest.php
Also I've tried running it various places in the folder structure. Here is the immediate structure:
/tests
| bootstrap.php
| my_tree.txt
| phpunit.xml
| WebTestCase.php
|
|---- /fixtures
|---- /functional
| SiteTest.php
|
|---- /report
`---- /unit
LittleTest.php
I also checked my php.ini for the path to PEAR; as far as I can tell, it's correct (but how can I test it?):
include_path=".;C:\wamp\bin\php\php5.3.5\PEAR;C:\wamp\www\app
More Info
In response to this:
cd wamp\www\app\protected\tests
phpunit unit\LittleTest.php
I receive this:

...et cetera...
The failed requirement is PHPUnit/Extensions/SeleniumTestCase.php. I wonder if the issue is that PHPUnit is installed locally under C:\wamp.
I opened my php.ini and added to include_path: C:\wamp\bin\php\php5.3.5\PEAR\PHPUnit\Extensions. Restarted wamp. No change in error reporting.
RESOLUTION
My security setup uses DansGuardian and I had neglected to loosen the settings for banned extension types, which blocks file downloads. In fact I don't care to ban any types, and modifying that file allows everything to work. Woops, that's my Linux set. PHPUnit is working there, and it is working on WAMP also. Recreating the steps on WAMP is impossible; but I do know I had to open cmd.exe as administrator and pear update-channels, pear upgrade-all, etc. I also had to clear pear's cache at one point, and I had to overcome an issue with curl recognition to install Selenium:
pear install --force phpunit/PHPUnit_Selenium

To run unit tests in Yii with phpunit, you'll need to let phpunit load the protected/tests/bootstrap.php file which basically sets up a configuration, and autoloads the required classes (mainly pertaining to testing). The bootstrap.php file loads yiit.php which actually autoloads the required classes.
Now we can load all this configuration either by command line options when running phpunit, or let the configuration be read automatically through the protected/tests/phpunit.xml file.
For the latter method, the directory from where phpunit is invoked should have the phpunit.xml file in it, and in Yii default webapp, this directory is protected/tests. Therefore you need to do the following to run your tests:
cd wamp\www\app\protected\tests
phpunit unit\LittleTest.php
