php - write a PHPUnit Test for some classes i am new PHPUnit user -

i want write phpunit test classes

and sure know how execute phpunit

1000 helper :)

irandomgenerator.php

<?php /**  * random generator interface  *   * @package gns  */  interface irandomgenerator {   /**      * random byte      *       * @return int 0..255 range integer      * @throws nomorebytesexception      */     public function getbyte(); }  /**  * no more bytes can exception  *   * can useful if generator depends on external source  */ class nomorebytesexception extends exception {} ?> 

arandomgenerator.class.php

<?php /**  * base class random generators  */  require_once 'irandomgenerator.php';  abstract class arandomgenerator implements irandomgenerator {   /**      * bytes      *       * @param int $number      * @return array array of 0..255 range integers      * @throws nomorebytesexception      */     public function getbytes($number = 1)     {       $bytes = array();       ($i = 0; $i < $number; $i++) $bytes[] = $this->getbyte();       return $bytes;     }       /**      * word      *       * @return int 0..65535 range integer      * @throws nomorebytesexception      */     public function getword()     {       return $this->getbyte() << 8 | $this->getbyte();     }       /**      * words      *       * @param int $number      * @return array array of 0..65535 range integers      * @throws nomorebytesexception      */     public function getwords($number = 1)     {       $words = array();       ($i = 0; $i < $number; $i++) $words[] = $this->getword();       return $words;     }       /**      * long      *       * @return 4-byte integer      * @throws nomorebytesexception      */     public function getlong()     {       return $this->getword() << 16 | $this->getword();     }       /**      * longs      *       * @param int $number      * @return array array of 4-byte integers      * @throws nomorebytesexception      */     public function getlongs($number = 1)     {       $longs = array();       ($i = 0; $i < $number; $i++) $longs[] = $this->getlong();       return $longs;     } } ?> 

filerandomgenerator.class

<?php /**  * file random generator (reading data file)  *   * take care of file holds random data  * , contains enough task. don't use same  * data twice  */  require_once 'arandomgenerator.class.php';  class filerandomgenerator extends arandomgenerator {   /** @const int chunk read file */   const chunksize = 128;    /** @var array $pool of data */   private $pool = array();    /** @var resourse open file descriptor */   private $fd;     /**    * constructor    *     * @param string $fname file name random data    */   public function __construct($fname)   {     $this->fd = fopen($fname, 'rb');     if ($this->fd === false) throw new nomorebytesexception('cannot open file: ' . $fname);   }       /**      * random byte      *       * @return int 0..255 range integer      * @throws nomorebytesexception      */     public function getbyte()     {       // reading pool       if (count($this->pool) === 0)       {       if (($data = fread($this->fd, self::chunksize)) !== false)         $this->pool = unpack('c*', $data);         else           throw new nomorebytesexception('no more data in file left');       }        return array_pop($this->pool);     } } ?> 

and how know function phpunit framework must use test each class ?

one easy way started use phpunit-skelgen. utility set bare-bones test class.

you want read manual, "tl;dr" is:

$ mkdir -pv tests/unit $ phpunit-skelgen --test -- filerandomgenerator filerandomgenerator.class.php \    filerandomgeneratortest tests/unit/filerandomgeneratortest.php
