我正在关注rails3tutorial,在进行一些测试时我不明白"it"关键字的含义如下:

require 'spec_helper'

describe UsersController do
  render_views

  describe "GET 'new'" do
    it "should be successful" do
      get 'new'
      response.should be_success
    end

    it "should have the right title" do
      get 'new'
      response.should have_selector("title", :content => "Sign up")
    end
  end
end

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. …
