如何通过phpunit上的所有测试保留会话？

Question

我正在使用phpunit测试Zend Framework上的购物车,结帐,付款流程.我正在ShoppingCartController通过向购物车添加产品进行测试,ShoppingCart模型通过将产品ID存储在Zend会话命名空间中来处理产品添加,然后在另一个测试中我想测试产品是否已添加.同一个ShoppingCartModel从同一个Zend Session命名空间变量中检索添加的产品列表.

添加产品测试看起来像这样并且运行良好,并且var_dump($_SESSION)已添加到调试并正确显示产品:

public function testCanAddProductsToShoppingCart() {

    $testProducts = array(
        array(
            "product_id" => "1",
            "product_quantity" => "5"
        ),
        array(
            "product_id" => "1",
            "product_quantity" => "3"
        ),
        array(
            "product_id" => "2",
            "product_quantity" => "1"
        )
    );

    Ecommerce_Model_Shoppingcart::clean();

    foreach ($testProducts as $product) {
        $this->request->setMethod('POST')
                ->setPost(array(
                    'product_id' => $product["product_id"],
                    'quantity' => $product["product_quantity"]
                ));

        $this->dispatch($this->getRouteUrl("add_to_shopping_cart"));
        $this->assertResponseCode('200');
    }

    $products = Ecommerce_Model_Shoppingcart::getData();
    $this->assertTrue($products[2][0]["product"] instanceof Ecommerce_Model_Product);
    $this->assertEquals($products[2][0]["quantity"],
            "8");

    $this->assertTrue($products[2][1]["product"] instanceof Ecommerce_Model_Product);
    $this->assertEquals($products[2][1]["quantity"],
            "1");

    var_dump($_SESSION);
}

第二个测试尝试通过询问模型来检索产品var_dump($_SESSION),在测试开始时已经为null.会话变量被重置,我想找到一种方法来保存它们,任何人都可以帮忙吗？

public function testCanDisplayShoppingCartWidget()  {
    var_dump($_SESSION);
    $this->dispatch($this->getRouteUrl("view_shopping_mini_cart"));
    $this->assertResponseCode('200');
}

很抱歉指向错误的方向.这是一种实现这一目标的更好方法,由irha.freenode.net的#phpunit频道的ashawley建议:

<?php

# running from the cli doesn't set $_SESSION here on phpunit trunk
if ( !isset( $_SESSION ) ) $_SESSION = array(  );

class FooTest extends PHPUnit_Framework_TestCase {
    protected $backupGlobalsBlacklist = array( '_SESSION' );

    public function testOne(  ) {
        $_SESSION['foo'] = 'bar';
    }

    public function testTwo(  ) {
        $this->assertEquals( 'bar', $_SESSION['foo'] );
    }

}

?>

== END UPDATE

1. 在函数tearDown()中:将$ _SESSION复制到类属性和
2. 在函数setUp()中:将class属性复制到$ _SESSION

例如,删除函数setUp()和tearDown()方法时,此测试失败:

<?php
# Usage: save this to test.php and run phpunit test.php    

# running from the cli doesn't set $_SESSION here on phpunit trunk                                                                                                
if ( !isset( $_SESSION ) ) $_SESSION = array(  );

class FooTest extends PHPUnit_Framework_TestCase {
    public static $shared_session = array(  ); 

    public function setUp() {
        $_SESSION = FooTest::$shared_session;
    }  

    public function tearDown() {

        FooTest::$shared_session = $_SESSION;
    }  

    public function testOne(  ) {
        $_SESSION['foo'] = 'bar';
    }  

    public function testTwo(  ) {
        $this->assertEquals( 'bar', $_SESSION['foo'] ); 
    }  
}

还有一个backupGlobals功能,但它不适合我.你应该试一试,也许它适用于稳定的PHPUnit.
