与Selenium / Ubuntu的PHPUnit致命错误

I have gone through various tutorials/posts to install PHPUnit with Selenium on my Ubuntu system. I believe I have everything setup as required:

/usr/share/php$ phpunit --version
PHPUnit 3.6.10 by Sebastian Bergmann.

So using the IDE I create my test, and save it for running, which appears to be setup as required. So I run the test using:

phpunit /home/retrobadger/working_files/tutorials/phpunit/selenium1.php

But everytime I run it, I get the error below:

PHP Fatal error:  Class 'PHPUnit_Extensions_SeleniumTestSuite' not found in /usr/share/php/PHPUnit/Extensions/SeleniumTestCase.php on line 394
PHP Stack trace:
PHP   1. {main}() /usr/bin/phpunit:0
PHP   2. PHPUnit_TextUI_Command::main() /usr/bin/phpunit:46
PHP   3. PHPUnit_TextUI_Command->run() /usr/share/php/PHPUnit/TextUI/Command.php:130
PHP   4. PHPUnit_Runner_BaseTestRunner->getTest() /usr/share/php/PHPUnit/TextUI/Command.php:150
PHP   5. ReflectionMethod->invoke() /usr/share/php/PHPUnit/Runner/BaseTestRunner.php:124
PHP   6. PHPUnit_Extensions_SeleniumTestCase::suite() /usr/share/php/PHPUnit/Extensions/SeleniumTestCase.php:0

The file in extensions exists, and I have set very open priviledges to it. The only things I can think of are that either my SeleniumTestCase.php is faulty, or that I need to require another file no other tutorials have suggested.

Any recommendations would be greatly appreciated. I have little experience with PHPUnit so expect my mistake is a basic one.

Thanks for any advice you can give, Dan

Check that you include PHPUnit when you call tests.. either in php.ini, or with IDE that you run, or explicitly - right now it just can't find class.. which means that PHPUnit is not reachable. Try a simplier class, PHPUnit_Extensions_SeleniumTestCase
