PHPUnit笔记(一)
最近构想自己要做的项目,涉及到web上的东西,要用php来做,因此自然就接触到了phpunit这个东西。
开发平台:Debian
首先是安装PHPUnit,配置环境当然是越简单越好,我是个懒人,我认...
1 | pear channel-discover pear.phpunit.de |
2 | pear channel-discover components.ez.no |
3 | pear channel-discover pear.symfony-project.com |
4 | pear install phpunit/PHPUnit |
结束后,会等一阵子,一开始我心急了,看见没啥反映,就直接ctrl+c了。事实证明我2了。
安装需要pear,当然,获取方法也继续 my style。
1 | apt-get install php5-curl php-pear | 安装curl,pear |
2 | pear upgrade-all | 更新软件包 |
一切就绪后,可以在终端里输入phpunit,如果没有反映,就准备好好找原因吧。反正我相信linux上的软件问题,大多是依赖问题,以前尝试玩过lfs,好家伙,没让我少死脑细胞。
接着是使用phpunit。
根据baidu和google,大多使用如下:
<?php require_once 'PHPUnit/Framework.php'; class ExceptionTest extends PHPUnit_Framework_TestCase { /** * @expectedException InvalidArgumentException */ public function testException() { } } ?>
然后在终端输入
1 | phpuint test.php | test.php为测试代码文件 |
悲剧的是,找不到PHPUnit/Framework.php这个文件,于是查看php.ini的include_path参数后,找到了phpunit目录,发现了Framework目录。
<?php require_once 'PHPUnit/Framework/TestCase.php'; class ArrayTest extends PHPUnit_Framework_TestCase{ public function testNewArrayIsEmpty(){ /*Create the Array fixture*/ $fixture = array(); /* Assert that the size of the Array * fixture is 0*/ $this->assertEquals(0, sizeof($fixture)); } public function testArrayContainsAnElement(){ /* Create the Array fixture*/ $fixture = array(); /*Add an element to the Array * fixture*/ $fixture[] = 'Element'; /*Assert that the size of the * Array fixture is 1*/ $this->assertEquals(1, sizeof($fixture)); } } ?>
这次ok了,基本上一个简单的testcase就是跑通了。
当然,如果测试文件比较多,这么挨个phpunit,是相当蛋疼的事情。所以,我去找到了xml配置文件的使用方法。
<phpunit> <testsuites> <testsuite name="Object_Freezer_Directory"> <directory>Tests</directory> </testsuite> <testsuite name="Object_Freezer_File"> <file>Tests/Freezer/HashGenerator/NonRecursiveSHA1Test.php</file> <file>Tests/Freezer/IdGenerator/UUIDTest.php</file> <file>Tests/Freezer/UtilTest.php</file> <file>Tests/FreezerTest.php</file> <file>Tests/Freezer/StorageTest.php</file> <file>Tests/Freezer/Storage/CouchDB/WithLazyLoadTest.php</file> <file>Tests/Freezer/Storage/CouchDB/WithoutLazyLoadTest.php</file> </testsuite> </testsuites> </phpunit>
大概就是这样,可以去http://www.phpunit.de/manual/3.6/en/index.html了解更多的用法。
1 | phpunit --configuration test.xml --debug | test.xnl为测试配置文件 |
ok,第一份笔记完毕。
最后感慨下,phpunit真的是相当不错,想java用JUnit,要mock还需要Jmock,easymock;net也差不多,单元测试NUnit,mock需要Rhino Mocks;c就更要泪奔了。phpunit,不仅仅包含mock,连Code Coverage都有,不得不赞叹下啊。

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.
