PHPUnit - 如何在 PHPUnit_Framework_TestCase 中实例化我的 pdo class?
PHPUnit - How to instantiate my pdo class in PHPUnit_Framework_TestCase?
如何在 PHPUnit_Framework_TestCase 中实例化我的 pdo class?
例如,这是我的 \test\SuitTest.php
,
namespace Test;
use PHPUnit_Framework_TestCase;
class SuiteTest extends PHPUnit_Framework_TestCase
{
protected $PDO = null;
public function __construct()
{
parent::__construct();
$this->PDO = new \Foo\Adaptor\PdoAdaptor(); // the pdo is not instantiated at all - I think!
}
protected function truncateTables ($tables)
{
foreach ($tables as $table) {
$this->PDO->truncateTable($table);
}
}
/**
* DO NOT DELETE, REQUIRED TO AVOID FAILURE OF NO TESTS IN FILE
* PHPUnit is ignoring the exclude in the phpunit.xml config file
*/
public function testDummyTest()
{
}
}
我想使用我用于开发和生产的 pdo class,它位于 \app\source\Adaptor\PdoAdaptor.php
,
<?php
namespace Foo\Adaptor;
use PDO;
class PdoAdaptor
{
protected $PDO = null;
protected $dsn = 'mysql:host=localhost;dbname=phpunit', $username = 'root', $password = 'xxxx';
/*
* Make the pdo connection.
* @return object $PDO
*/
public function connect()
{
try {
$this->PDO = new PDO($this->dsn, $this->username, $this->password, array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
$this->PDO->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// Unset props.
unset($this->dsn);
unset($this->username);
unset($this->password);
} catch (PDOException $error) {
// Call the getError function
$this->getError($error);
}
}
public function truncateTable($table)
{
$sql = "TRUNCATE TABLE $table";
$command = $this->PDO->prepare($sql);
$command->execute();
}
}
当我 运行 phpunit
测试我的代码时出现此错误,
Fatal error: Call to a member function prepare() on null
pdo 根本没有在 SuiteTes
t 中的 construct
方法中实例化 - 我认为!
这是我的目录结构,
您应该使用设置方法而不是覆盖 PHPUnit_Framework_TestCase 构造函数,即只需将 SuiteTest class 中的构造函数定义替换为:
public function setup()
{
$this->PDO = new \Foo\Adaptor\PdoAdaptor();
}
使用setUpBeforeClass
方法(注意:它是静态的)
protected static $pdo;
public static function setUpBeforeClass()
{
static::$pdo = new PdoAdapter();
}
然后只需在测试中使用 static::$pdo
或 self::$pdo
访问您的 pdo 实例。
