PHPUnit 入门篇

     <p><strong><a href="http://www.open-open.com/lib/view/open1322626665421.html" target="_blank">PHPUnit</a>是什么？</strong></p>    <p>它是一款轻量级的php测试框架</p>    <p><strong>为什么要用PHPUnit？</strong></p>    <p>1. 非死book在用</p>    <p>2. 可以通过命令操控测试脚本</p>    <p>3. 可以测试性能</p>    <p>4. 可以测试代码覆盖率</p>    <p>5. 可以自动化的更新测试用例的参数数据</p>    <p>6. 各种格式的日志</p>    <p>6. 最最重要的是，功能如此炫，使用起来还特别简单</p>    <p><strong>PHPUnit的安装</strong></p>    <pre class="brush:php; toolbar: true; auto-links: false;"><strong>pear channel-discover pear.phpunit.de   pear install phpunit/PHPUnit  </strong></pre>    <strong>快速入门<pre class="brush:php; toolbar: true; auto-links: false;"><?php require_once 'PHPUnit/Framework.php';   class ArrayTest extends PHPUnit_Framework_TestCase {     public function testNewArrayIsEmpty()     {         // 创建数组fixture。         $fixture = array();           // 断言数组fixture的尺寸是0。         $this->assertEquals(0, sizeof($fixture));     } } ?></pre></strong>    <p></p>    <p>1. ArrayTest为测试类</p>    <p>2. ArrayTest 继承于PHPUnit_Framework_TestCase</p>    <p>3.测试方法testNewArrayIsEmpty()，测试方法必须为public权限，一般以test开头，或者你也可以选择给其加注释@test来表明该函数为测试函数</p>    <pre class="brush:php; toolbar: true; auto-links: false;">/** * @test */ public function testNewArrayIsEmpty() {      $fixture = array();      $this->assertEquals(0, sizeof($fixture)); }</pre>    <p></p>    <p><strong>命令行启动测试</strong></p>    <p>phpunit  测试文件名，此处为要测试ArrayTest.php文件</p>    <p>phpunit ArrayTest<br /> PHPUnit 3.2.10 by Sebastian Bergmann.<br /> ..<br /> Time: 0 seconds<br /> OK (2 tests)</p>    <p>命令行参数</p>    <pre class="brush:php; toolbar: true; auto-links: false;">phpunit --help PHPUnit 3.2.10 by Sebastian Bergmann.
