問題
在Yii中執行測試用例時報錯，內容如下：
PHP Warning: require_once(PHPUnit/Runner/Version.php):
failed to open stream:
No such file or directory in /home/work/software/yii/framework/test/CTestCase.php on line 11
Warning: require_once(PHPUnit/Runner/Version.php):
failed to open stream:
No such file or directory in /home/work/software/yii/framework/test/CTestCase.php on line 11
PHP Fatal error:
require_once(): Failed opening required `PHPUnit/Runner/Version.php` (include_path=`...`) in /home/work/software/yii/framework/test/CTestCase.php on line 11
Fatal error: require_once():
Failed opening required `PHPUnit/Runner/Version.php` (include_path=`...`) in /home/work/software/yii/framework/test/CTestCase.php on line 11原因
使用的phpunit版本為5.7，使用該版本時，不再需要顯示包含PHPUnit/Runner/Version.php等標頭檔案了。
而我當前使用的Yii版本為1.1.15，在yii/framework/test/CTestCase.php中可以看到以下內容：
require_once(`PHPUnit/Runner/Version.php`);
require_once(`PHPUnit/Util/Filesystem.php`); // workaround for PHPUnit <= 3.6.11
spl_autoload_unregister(array(`YiiBase`,`autoload`));
require_once(`PHPUnit/Autoload.php`);可以看到，它顯示包含了phpunit中的PHPUnit/Runner/Version.php, PHPUnit/Util/Filesystem.php, PHPUnit/Autoload.php的檔案，將其註釋掉即可。
// require_once(`PHPUnit/Runner/Version.php`);
// require_once(`PHPUnit/Util/Filesystem.php`); // workaround for PHPUnit <= 3.6.11
spl_autoload_unregister(array(`YiiBase`,`autoload`));
// require_once(`PHPUnit/Autoload.php`);
