Rails - 期待＆lt;＆＃34;类别/索引＆＃34;＆gt;但使用＆lt; []＆gt;进行渲染

Question

我正在尝试运行测试，但看到以下错误

  

＆＃34; CreateCategoriesTest＃test_get_new_category_form_and_create_category [/Users/imcglobal/Desktop/RailsDevelopement/blog/test/integration/create_categories_test.rb:10]：   期待＆lt;＆＃;;类别/索引＆＃34;＆gt;但使用＆lt; []＆gt;＆＃34;

进行渲染

下面是测试细节

test "get new category form and create category" do
    get new_category_path
    assert_template 'categories/new'
    assert_difference 'Category.count', 1 do
        post categories_path, category: {name: "sports"}
    end
    assert_template 'categories/index' **#line 10**
    assert_match "sports", response.body
end


#categories controller
def index
    @categories = Category.all
end

我的索引文件循环通过类别对象。任何人都可以让我知道我错过了什么。感谢。

Answer 1

只需在follow_redirect!之后添加post categories_path, category: {name: "sports"}

post categories_path, category: {name: "sports"}
follow_redirect!

Answer 2

也许这篇文章将来会帮助某人。

你需要改变

post categories_path, category: {name: "sports"}

到

post_via_redirect categories_path, category: {name: "sports"}
