Question

我是编码的新手，希望我遵循所有规则来发布这个问题。

我正在阅读Ruby on Rails的介绍，在我的一个例子中，当GUARD运行时，我得到以下'Unexpect tIDENTIFIER'消息，我似乎无法找出原因。

ERROR["test_should_get_about", StaticPagesControllerTest, 0.012288]

我的StaticPagesControllerTest如下：

require 'test_helper'

class StaticPagesControllerTest < ActionController::TestCase

test "should get home" do
get :home
assert_response :success
assert_select "title", 'Home | Ruby on Rails Tutorial Sample App'
end

 test "should get help" do
get :help
assert_response :success
assert_select "title", 'Help | Ruby on Rails Tutorial Sample App'

end

test "should get about" do
get :about
assert_response :success
assert_select 'title", "About | Ruby on Rails Tutorial Sample App'

end

end

Answer 1

您的错误是您使用不一致的单引号和双引号：

test "should get about" do
get :about
assert_response :success
assert_select 'title", "About | Ruby on Rails Tutorial Sample App'
# ------------^ here

end

这是更主观的，但为了避免这种错误，选择一个（单个或双重）并坚持它可能是一个好主意，除非你必须使用别的东西（即做{{1}字符串插值）
