正在看 restful rail development 这本书，按照书上写的测试报错了，大佬帮我看看

rails 版本 5.2.2
require 'test_helper'

class SayControllerTest < ActionDispatch::IntegrationTest
test "should get hello" do
get say_hello_url
assert_response :success
end
test "should say hello in json" do
get say_hello_url
assert_equal "{\"hello\":\"Rails!\"}", @response.body
end
test "should say hello in json" do
get say_hello_url,{'user'=>"Join"}
assert_equal "{\"hello\":\"Join!\"}", @response.body
end
end

先配置一下 config/database.yaml，然后执行 `rails db:migrate`
