路线在应用程序中有效，在 Cucumber 测试中失败

Question

I have a route that works (recognized, can follow it) in a Rails 3 application, but fails in the Cucumber test:

routes.rb:

resources :tests do
  member do
    post 'start'
  end
end

Working link in application:

=button_to 'Start', start_test_path(@test)

Gherkin step:

And I am on the test start page for "Sample Test"

Failing in paths.rb

when /the test start page for "([^\"]*)"/
  start_test_path(Test.find_by_name($1))

...

(::) failed steps (::)

No route matches "/tests/1/start" (ActionController::RoutingError)
<internal:prelude>:10:in `synchronize'
./features/step_definitions/web_steps.rb:30:in `/^(?:|I )am on (.+)$/'
features/test_workflow.feature:24:in `And I am on the test start page for "Sample Test"'

Any ideas? Thanks!

Answer 1

The reason is that 'start' is a post action, not a get action. When you use the I am on the... cucumber step you are generating a get request, not a post request. To fix this, simply press the button in Cucumber, instead of visiting the direct path. This can be done with the press cucumber step, like this:

When I press "Start"

This step will generate the appropriate post request, but it must be called after you visit the page that the button is located on. Alternatively, you can generate a post request in a custom cucumber step by doing something like this:

When /^I am on the test start page$/ do
  post("/tests/1/start")
end

Answer 2

I don't know cucumber, but try this:

Rename your route from test to tests and your controller from TestController to TestsController

This just might be a case where your naming conventions are messing things up, because they are not what Rails expects.

I don't know if I am right - just a guess.
