我有一些这样的代码库,我想使用 rspec 测试 favicon_href,但如你所愿,favicon_href 将调用页面函数,我知道我可以模拟页面函数,但在这个阶段我想模拟来自给定 url 的 HTTP 请求,所以我使用 WebMock gem 的语法来 stub HTTP 请求,但似乎 WebMock 与 Mechanize 不兼容,尽管我已经完成 stub ,但它总是在下面显示错误,任何人都知道如何解决它或任何 gem 都可以 stub HTTP要求 Mechanize ?
代码
def favicon_href
@favicon_href ||=
begin
page.at(FAVICON_DOM).attributes['href'].value # finding <link> elements
rescue Exception
'/favicon.ico' # there are some situation the favicon's not <link>'
end
end
def page
@page ||= mechanize.get(url)
end
def mechanize
@mechanize ||= Mechanize.new
end
错误
Failure/Error: @page ||= mechanize.get(valid_url(url))
WebMock::NetConnectNotAllowedError:
Real HTTP connections are disabled. Unregistered request: GET https://tsaohucn.wordpress.com/ with headers {'Accept'=>'*/*', 'Accept-Charset'=>'ISO-8859-1,utf-8;q=0.7,*;q=0.7', 'Accept-Encoding'=>'gzip,deflate,identity', 'Accept-Language'=>'en-us,en;q=0.5', 'Connection'=>'keep-alive', 'Host'=>'tsaohucn.wordpress.com', 'Keep-Alive'=>'300', 'User-Agent'=>'Mechanize/2.7.5 Ruby/2.3.1p112 (http://github.com/sparklemotion/mechanize/)'}
You can stub this request with the following snippet:
stub_request(:get, "https://tsaohucn.wordpress.com/").
with(headers: {'Accept'=>'*/*', 'Accept-Charset'=>'ISO-8859-1,utf-8;q=0.7,*;q=0.7', 'Accept-Encoding'=>'gzip,deflate,identity', 'Accept-Language'=>'en-us,en;q=0.5', 'Connection'=>'keep-alive', 'Host'=>'tsaohucn.wordpress.com', 'Keep-Alive'=>'300', 'User-Agent'=>'Mechanize/2.7.5 Ruby/2.3.1p112 (http://github.com/sparklemotion/mechanize/)'}).
to_return(status: 200, body: "", headers: {})
registered request stubs:
stub_request(:get, "https://tsaohucn.wordpress.com/").
with(headers: {'Accept'=>'*/*', 'User-Agent'=>'Ruby'})
stub_request(:any, "http://api.stripe.com/")
stub_request(:any, "/api.stripe.com/")

最佳答案
WebMock 和 net-http-persistent 之间存在不兼容。
看
https://github.com/bblimke/webmock#connecting-on-nethttpstart
添加WebMock.allow_net_connect!(:net_http_connect_on_start => true)
到您的测试设置。
