好的,所以我想创建一个测试,检查所有页面都有一定的标题。但是我认为如果我可以在array
中包含页面标题会很好,这样我就不必为每个页面复制块。这样我就可以通过修改pages array
来测试其他页面。
我遇到的问题是页面变量没有在测试中进行插值。那么这是语法错误还是Rspec不允许在it should do...
块内进行插值?
describe "LayoutLinks" do
page = ["home", "contact", "about", "help"]
i = page.count
x = 0
while x < i
it "should have a #{page[x]} page" do
get "#{page[x]}"
response.should have_selector("title", :content => "#{page[x]}")
end
x += 1
end
end
测试显示以下失败:
1) PagesController LayoutLinks should have a help page
Failure/Error: get "#{page[x]}"
ActionController::RoutingError:
No route matches {:controller=>"pages", :action=>""}
# ./spec/controllers/layout_links_spec.rb:14:in `block (3 levels) in <top (required)>'
2) PagesController LayoutLinks should have a contact page
Failure/Error: get "#{page[x]}"
ActionController::RoutingError:
No route matches {:controller=>"pages", :action=>""}
# ./spec/controllers/layout_links_spec.rb:14:in `block (3 levels) in <top (required)>'
3) PagesController LayoutLinks should have a about page
Failure/Error: get "#{page[x]}"
ActionController::RoutingError:
No route matches {:controller=>"pages", :action=>""}
# ./spec/controllers/layout_links_spec.rb:14:in `block (3 levels) in <top (required)>'
4) PagesController LayoutLinks should have a home page
Failure/Error: get "#{page[x]}"
ActionController::RoutingError:
No route matches {:controller=>"pages", :action=>""}
这里的失败错误是显而易见的。它不应该说得到"#{page[x]}"
,而应该是get home
和get about
等......
我该如何补救?谢谢您的帮助。非常感谢:)
答案 0 :(得分:0)
尝试以下方法:
describe "LayoutLinks" do
%w(home contact about help).each do |page|
it "should have a #{page} page" do
get page
response.should have_selector("title", content: page)
end
end
end
%w创建一个字符串数组(空格成为逗号,所以你得到[“home”,“contact”等])
