Cucumber Scaffolds

byrnejb · November 12, 2008, 5:18pm

I have installed all of the various bit and pieces for rspec and
cucumber
and have used:

script/generate feature Frooble name color description

To create a dummy feature and related steps. Now, while I have been
poking at Ruby, Rails, RSpec and Stories for a long time, I have never
really grasped much of what I have been exposed to. Therefore, I crave
your indulgence for the next little while as I buckle down to master
this
stuff. My questions over the next little while will likely be novice
level.

Taking the frooble skeleton I have reworked it to this:

#manage_entities.feature

Feature: Manage entities
In order to keep track of entities
A entity maintainer
Should be able to manage entities
To Protect Revenue

Scenario: Register a new entity
Given I am on the new entity page
When I fill in “entity_name” with “My New Entity”
And I fill in “entity_legal_name” with “My New Enitity is a CORP”
And I fill in “entity_legal_form” with “CORP”
And I press “Create”
Then I should see “My New Entity”
And I should see “My New Enitity is a CORP”
And I should see “CORP”
…

And

#steps/entity_steps.rb

Given /I am on the new entity page/ do
visits “/entities/new”
end
…

When I run # rake features I see this:

Feature: Manage entities # features/manage_entities.feature
In order to keep track of entities
A entity maintainer
Should be able to manage multiple entities
To Protect Revenue
Scenario: Register a new entity #
features/manage_entities.feature:7
Given I am on the new entity page #
features/steps/entity_steps.rb:1
undefined method `visits’ for
#ActionController::Integration::Session:0xb7202094 (NoMethodError)

Now, “visits” is an action predefined in the step file, and one that I
presume is connected somehow to webrat (installed), which means to me
that
I should not have to define it myself. Therefore my questions are: Is
there some manual configuration I am required to do to wire this up
correctly or am I missing the boat on this altogether? If there are
additional set-up steps that I must perform then where to I discover
them?

Do you have vendor/plugins/webrat ?
If you have webrat as a gem you must require ‘webrat’ in env.rb

Maybe the generated env.rb should have:
require ‘webrat’ if !defined?(Webrat)

Yes. That worked fine. Now I have another question. Please be patient
with me.

The features test now shows this:

$ rake features
(in /home/byrnejb/Software/Development/Projects/proforma.git)
Feature: Manage entities # features/manage_entities.feature
In order to keep track of entities
A entity maintainer
Should be able to manage multiple entities
To Protect Revenue
Scenario: Register a new entity #
features/manage_entities.feature:7
Given I am on the new entity page #
features/steps/entity_steps.rb:1
wrong number of arguments (3 for 1) (ActionView::TemplateError)
On line #10 of app/views/entities/new.html.erb

  7: <% form_for(@entity) do |f| %>
  8:
  9:   <%= render  :partial  => 'entities/entity_header',
  10:               :object   => @entity -%>
  11:
  12:   <p>
  13:   <%= f.submit "Create" -%>

  vendor/plugins/rspec-rails/lib/spec/rails/extensions/action_view/base.rb:13:in

render_partial' vendor/plugins/rspec-rails/lib/spec/rails/extensions/action_view/base.rb:13:in render_partial’

I am obviously retro-fitting tests on code that I have already written.
In this instance I have extracted code common to the new and the edit
views into a partial. What is this test error telling me and how do I
get
my feature/step to accommodate my existing ( and working ) code?

steps/entity_steps.rb

Given /I am on the new entity page/ do
visits “/entities/new”
end

This is just a side note, but is “manage entities” really a feature? It
sounds pretty vague. I’m not experienced with cucumber, so I don’t know
if
that’s typical usage.

Good catch. It is not - it’s just what the generator generates. Read
the disclaimer here:

feature)

Suggestions about how to generate starter-features that are at the
same time valuable features and tie into Rails’ REST are welcome.

Any hints on what I am doing wrong here? Should I be asking this
question
on a webrat list? Is there one? I cannot find it.

Thanks to a suggestion from the Ruby on Rails list I checked my vendor
plugins directory and discovered that I had not actually removed the
older
rspec and rspec-rails plugins, just detached them from git. They both
are
now gone and my tests are running, if not passing. But at least I am
past
this problem anyway.

A couple of tips may help here.

You can debug features by putting ‘debugger’ in the step file. Just
make sure there is a line after debugger

e.g

…
debugger
response
end

If there’s nothing after debugger you will stop in the cucumber code,
which is not what you want.

You can also put debugger statements in your rails files. Perhaps
you could do a

<%- debugger %>

before you render your partial in the form. (You might have to use <%=)

And require ruby-debug.

For what it is worth the contents of the log/test.log file are:

$ tail log/test.log
Completed in 67ms (View: 7, DB: 2) | 200 OK
[http://www.example.com/entities]
SQL (0.7ms) SELECT count(*) AS count_all FROM “entities”

Rendering entities/new

While, the same page rendered in Firefox using the development
environment
shows this:

REQUESTING PAGE: GET /entities/new with {} and HTTP headers {}

Processing EntitiesController#new (for 127.0.0.1 at 2008-11-12 15:11:44)

WHERE type = ‘table’ AND NOT name = ‘sqlite_sequence’

I really could use from help from someone who can explain this
behaviour.
