我的单元测试：

 require 'test_helper' 

class ProductTest < ActiveSupport::TestCase 

    def new_product 
     product = Product.new(:title => "MyBook", 
          :description => "Famouse myBook", 
          :image_url => "zz.jpg") 

    end 

    test "product attributes must not be empty" do 
     product = Product.new 
     assert product.invalid? 
     assert product.errors[:title].any? 
     assert product.errors[:description].any? 
     assert product.errors[:price].any? 
     assert product.errors[:image_url].any? 
    end 

    test "product must be postive price" do 
     product = Product.new(:title => "MyBook", 
          :description => "Famouse myBook", 
          :image_url => "zz.jpg") 

     product.price = -1 
     assert product.invalid? 
     assert_equal "must be greater than or equal to 0.01", 
     product.errors[:price].join('; ') 

     product.price = 0 
     assert product.invalid? 
     assert_equal "must be greater than or equal to 0.01", 
     product.errors[:price].join('; ') 

     product.price = 1 
     assert product.valid? 
    end 


    test "image url" do 
     ok = %w{fred.gif fred.jpg fred.png FRED.JPG FRED.PNG FRED.GIF 
        http://a.b.c/x/y/z/fred.gif} 
      bad = %w{fred.doc fred.gif/more fred.gif.more}  

      ok.each do |name| 
       assert new_product(name).valid?, "#{name} shoudn't be invalid" 
      end 


      bad.each do |b| 
      assert new_product(name).invalid?, "#{name} shoudn't be valid" 
      end 
     end 








end

require 'test_helper'

    def new_product(image_url) 
     product = Product.new(:title => "MyBook", 
          :description => "Famouse myBook", 
          :price => 1 , 
          :image_url => image_url) 

    end 

    test "product attributes must not be empty" do 
     product = Product.new 
     assert product.invalid? 
     assert product.errors[:title].any? 
     assert product.errors[:description].any? 
     assert product.errors[:price].any? 
     assert product.errors[:image_url].any? 
    end 

    test "product must be postive price" do 
     product = Product.new(:title => "MyBook", 
          :description => "Famouse myBook",

我无法弄清楚您的问题。因为您在上面的代码中没有使用任何setup,teardown方法。提供完整的测试用例或只检查方法setup和teardown有任何参数操作。这个问题只与此有关。
