使用phpunit进行接口自动化测试

年初一个偶然的机会接触到了phpunit，一个用PHP编程语言开发的开源软件，也是一个单元测试框架，有效利用的话可以大大提高接口遍历的效率。废话不多说，直接干货。

1.安装

在php的目录下

pear channel-discover pear; pear install phpunit/PHPUnit 

2.配置

首先新建一个lib文件夹存放的配置文件，然后再新建一个transfer.php的文件

<?phpfunction do_Post($url, $fields, $extraheader = array()){  $ch = curl_init();  curl_setopt($ch, CURLOPT_URL, $url);  curl_setopt($ch, CURLOPT_POST, true);  curl_setopt($ch, CURLOPT_POSTFIELDS, $fields );  curl_setopt($ch, CURLOPT_HTTPHEADER, $extraheader);  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // 获取数据返回  $output = curl_exec($ch);  curl_close($ch);  return $output;}function do_Get($url, $extraheader = array()){  $ch = curl_init();  curl_setopt($ch, CURLOPT_URL, $url);  curl_setopt($ch, CURLOPT_HTTPHEADER, $extraheader);  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // 获取数据返回:  //curl_setopt($ch, CURLOPT_VERBOSE, true);  $output = curl_exec($ch) ;  curl_close($ch);  return $output;}function do_Put($url, $fields, $extraheader = array()){  $ch = curl_init();  curl_setopt($ch, CURLOPT_URL, $url ) ;  curl_setopt($ch, CURLOPT_POST, true) ;  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');  curl_setopt($ch, CURLOPT_POSTFIELDS, $fields );  curl_setopt($ch, CURLOPT_HTTPHEADER, $extraheader);  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // 获取数据返回  //curl_setopt($ch, CURLOPT_ENCODING, '');  $output = curl_exec($ch);  curl_close($ch);  return $output;}function do_Delete($url, $fields, $extraheader = array()){  $ch = curl_init();  curl_setopt($ch, CURLOPT_URL, $url ) ;  curl_setopt($ch, CURLOPT_POST, true);  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'DELETE');  curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);  curl_setopt($ch, CURLOPT_HTTPHEADER, $extraheader);  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // 获取数据返回  //curl_setopt($ch, CURLOPT_ENCODING, '');  $output = curl_exec($ch);  curl_close($ch);  return $output;}

最后新建一个basetest.php文件

<?php require_once("transfer.php"); define("PREFIX", "http://xxx"); define("HTTPSPREFIX", "https://xxx");  function build_get_param($param) {     return http_build_query($param); } 

到此接口测试环境搭建完成。

3.编写测试用例

<?php$basedir = dirname(__FILE__);require_once($basedir . '/lib/basetestdev.php');define("PHONE", "xxx");define("PWD", "xxx");define("POSTURL","xxx");class TestAPI extends PHPUnit_Framework_TestCase {    private function call_http($path, $param, $expect = 'ok') {        $_param = build_get_param($param);        $url = PREFIX . "$path?" . $_param;        $buf = do_Get($url);        $obj = json_decode($buf, True);        $this->assertEquals($obj['retval'], $expect);        return $obj;    }    private function call_https($path, $param, $expect = 'ok') {        $_param = build_get_param($param);        $url = HTTPSPREFIX . "$path?" . $_param;        $buf = do_Get($url);        $obj = json_decode($buf, True);        $this->assertEquals($obj['retval'], $expect);        return $obj;    }  public function testLogin(){    $param = array(      'type' => 'phone'      ,'token' => PHONE      ,'password' => PWD    );    $url = 'login';    return $this->call_http($url, $param);  }  /**   * @depends testLogin   */  public function testInfo(array $user){    $session = $user['retinfo']['session'];    $param = array(      'session' => $session    );    $url ='info';    return $this->call_http($url, $param);  }
