Automated testing of interfaces using phpunit

At the beginning of the year, I came into contact with phpunit by chance, an open source software developed with PHP programming language, and also a unit test framework, which can greatly improve the efficiency of interface traversal if used effectively. Needless to say, dry goods directly.

Step 1 Install

Under the directory of php

pear channel-discover pear; 
pear install phpunit/PHPUnit 

2. Configuration

First, create a new configuration file stored in the lib folder, and then create a new transfer. php file

<?php
function 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); //  Get data return 
  $output = curl_exec($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); //  Get data return :
  //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); //  Get data return 
  //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); //  Get data return 
  //curl_setopt($ch, CURLOPT_ENCODING, '');
  $output = curl_exec($ch);
  curl_close($ch);
  return $output;
}

Finally, create a new basetest. php file

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

To this interface, the test environment is built.

3. Write test cases

<?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);
  }

If it is an post request

public function testPost(){ 
    $session = $user['retinfo']['sessionid']; 
    $param = array( 
      ,'data' => '111' 
    ); 
    $url = POSTURL.'posturl'; 
    return do_POST($url,$param); 
  }
