我试图伪造对方法调用的响应,但没有成功。
在我的测试中,呈现html的页面将显示来自其中的页面数。调用<%= @pagy.pages %>
(我使用的是Pagy gem),但是在我的测试中,我不需要对页面进行计数,只需要检查页面是否已打开即可。
因此,@ pagy从未在测试中初始化。
我需要Minitest来“伪造” @pagy.pages
的答案,以便始终响应数字1
:
该怎么做?
谢谢!
在@Ahmed回答之后,这是新代码,但仍然无法正常工作:
mock = MiniTest::Mock.new
mock.expect :pages, 1
Pagy.stub :new, mock do
create :lando, :brazilo
get '/ameriko/brazilo'
assert_response :success
end
该视图仍然找不到@pagy.pages
方法。
答案 0 :(得分:1)
您可以在setup
块中使用Minitest Mocks(如果将此代码放入测试用例块本身也可以使用):
mock = Minitest::Mock.new
mock.expect :pages, 1
Pagy.stub :new, mock do
# Put the code that relies on `@pagy.pages` is `1`
end
回溯:
