我該如何在Zend_Db中測試我的映射器？ 我的每一個模型都將有3類：Zend Framework：我應該如何在Zend_Db中測試我的Mapper？
- 示範
- 的映射
- 的DBTABLE
這裏是我的單元測試：
<?php
// Call Model_BugTest::main() if this source file is executed directly.
if (!defined("PHPUnit_MAIN_METHOD")) {
define("PHPUnit_MAIN_METHOD", "Model_ArtistTest::main");
}
require_once dirname(__FILE__) . '/../../TestHelper.php';
/** Model_Artist */
require_once 'Artist.php';
/**
* Test class for Model_Artist.
*
* @group Models
*/
class Model_ArtistTest extends PHPUnit_Framework_TestCase
{
/**
* Runs the test methods of this class.
*
* @return void
*/
public static function main()
{
$suite = new PHPUnit_Framework_TestSuite("Model_ArtistTest");
$result = PHPUnit_TextUI_TestRunner::run($suite);
}
/**
* Sets up the fixture, for example, open a network connection.
* This method is called before a test is executed.
*
* @return void
*/
public function setUp()
{
$this->model = new Ly_Model_Artist();
}
/**
* Tears down the fixture, for example, close a network connection.
* This method is called after a test is executed.
*
* @return void
*/
public function tearDown()
{
}
public function testCanDoTest()
{
$this->assertTrue(true);
}
public function testCanFindArtist()
{
$artist = "Rage Against the Machine";
$result = $this->model->findbyalpha($artist);
var_dump($result);
}
}
我使用Matthew的TestHelper：http://github.com/weierophinney/bugapp/blob/master/tests/TestHelper.php
我得到的錯誤是這樣的：
c:\xampp\htdocs\ly\tests>phpunit --configuration phpunit.xml
PHPUnit 3.4.10 by Sebastian Bergmann.
.
Fatal error: Class 'Ly_Model_ArtistMapper' not found in C:\xampp\htdocs\ly\appli
cation\models\Artist.php on line 72
好像映射器沒有被讀取。任何人都可以告訴我如何做這種測試？我是UnitTesting的新手，我剛開始學習它。
這是我的藝人型號
<?php
/**
* Artist Model
*/
class Ly_Model_Artist
{
protected $_id; //a field
protected $_name; //a field
protected $_mapper;
public function __construct(array $options = null)
{
if (is_array($options)) {
$this->setOptions($options);
}
}
public function __set($name, $value)
{
$pieces = explode('_', $name);
foreach($pieces AS $key => $row) {
$pieces[$key] = ucfirst($row);
}
$name = implode('',$pieces);
$method = 'get' . $name;
if (('mapper' == $name) || !method_exists($this, $method)) {
throw new Exception('Invalid group property');
}
$this->$method($value);
}
public function __get($name)
{
$pieces = explode('_', $name);
foreach($pieces AS $key => $row) {
$pieces[$key] = ucfirst($row);
}
$name = implode('',$pieces);
$method = 'get' . $name;
if (('mapper' == $name) || !method_exists($this, $method)) {
throw new Exception('Invalid group property');
}
return $this->$method();
}
public function setOptions(array $options)
{
$methods = get_class_methods($this);
foreach ($options as $key => $value) {
$method = 'set' . ucfirst($key);
if (in_array($method, $methods)) {
$this->$method($value);
}
}
return $this;
}
public function setMapper($mapper)
{
$this->_mapper = $mapper;
return $this;
}
public function getMapper()
{
if (null === $this->_mapper) {
$this->setMapper(new Ly_Model_ArtistMapper());
}
return $this->_mapper;
}
public function setId($id)
{
$this->_id = (int) $id;
return $this;
}
public function getId()
{
return $this->_id;
}
public function setName($text)
{
$this->_name = (string) $text;
return $this;
}
public function getName()
{
return $this->_name;
}
public function find($id)
{
$this->getMapper()->find($id, $this);
return $this;
}
public function findbyalpha($keyword)
{
return $this->getMapper()->findbyalpha($keyword);
}
}
這是藝術家的映射：
<?php
/**
* Artist Model Mapper
*/
class Ly_Model_ArtistMapper
{
protected $_dbTable;
public function setDbTable($dbTable)
{
if (is_string($dbTable)) {
$dbTable = new $dbTable();
}
if (!$dbTable instanceof Zend_Db_Table_Abstract) {
throw new Exception('Invalid table data gateway provided');
}
$this->_dbTable = $dbTable;
return $this;
}
public function getDbTable()
{
if (null === $this->_dbTable) {
$this->setDbTable('Ly_Model_DbTable_Artist');
}
return $this->_dbTable->getAdapter();
}
public function find($id, Ly_Model_Artist $artist)
{
if(!isset($id) OR empty($id)) {
throw new Exception ('Could not find id.');
}
$result = $this->getDbTable()->find($id);
if (0 == count($result)) {
return;
}
$row = $result->current();
$artist->setId($row->id)
->setName($row->name);
}
public function findbyalpha($keyword)
{
if(!isset($keyword) OR empty($keyword)) {
throw new Exception ('Could not find keyword.');
}
$keyword = $this->getDbTable()->quote($keyword.'%');
//$sql = $this->getDbTable()->select()->where('twitter_id = ?',$twitter_id)->order('weight');
$sql = "SELECT
DISTINCT
a.name
FROM artist a
WHERE a.name LIKE ".$keyword."
ORDER BY a.name ASC
";
//Zend_Debug::dump($sql);
$result = $this->getDbTable()->fetchAll($sql);
return $result;
}
}
而且Db_Table看起來就像這樣：
<?php
class Ly_Model_DbTable_Artist extends Zend_Db_Table_Abstract
{
protected $_name = 'artist';
}
這不是使集成測試代替單元測試嗎？ OP詢問的單元測試應該單獨測試每個類，而不是測試依賴關係鏈。我認爲@ mfacenet的答案是正確的想法。 – curtisdf
