Write functional test cases for an rails app having no model

Rails
1

Hi,

I have a rails application that has a Application controller that
exposes REST API. And for the data I am using a third party module
instead of rails Model.

REST API:
http://myApp/plugins

Route.rb:
match “/plugins” => “plugins#get_plugins”, :via => “get”

My controller has following method:
def get_plugins
render :text=> third_party_module.get_plugins()
end

third_party_module.get_plugins() is the third party module that returns
data.

Functional test file: plugins_controller_test.rb has the following test
method:
test “should get plugins” do
get :get_plugins
assert_response :success
end

When I am trying to run functional test, it gives following error:
“db/schema.rb doesn’t exist yet. Run “rake db:migrate” to create it then
try again”

As I am not using any database.

Please help.

Regards,
Anil

I can reproduce your problem.

On rails 3.1.3, when installing the “standard” way, I get this:

peterv@ASUS:~/b/rails-apps/apps/temp/with_AR$ rails new with_AR
–skip-bundle
…

add gem ‘therubyracer’ to Gemfile and run bundle install

…
peterv@ASUS:~/b/rails-apps/apps/temp/with_AR$ rake environment
peterv@ASUS:~/b/rails-apps/apps/temp/with_AR$ rake test:functionals
/home/peterv/data/backed_up/rails-apps/apps/temp/with_AR/db/schema.rb
doesn’t exist yet. Run “rake db:migrate” to create it then try again. If
you do not intend to use a database, you should instead alter
/home/peterv/data/backed_up/rails-apps/apps/temp/with_AR/config/application.rb
to limit the frameworks that will be loaded

So, to me this is quite clear about the issue …

As easy solution, I then installed without ActiveRecord (read rails help
to find out):

peterv@ASUS:~/b/rails-apps/apps/temp$ rails new without_AR --skip-bundle
–skip-active-record
…

add gem ‘therubyracer’ to Gemfile and run bundle install

…
peterv@ASUS:~/b/rails-apps/apps/temp/without_AR$ rake environment
peterv@ASUS:~/b/rails-apps/apps/temp/without_AR$ rake test:functionals
#=> OK

The difference is this:

peterv@ASUS:~/b/rails-apps/apps/temp/without_AR$ diff
…/with_AR/config/application.rb config/application.rb
3c3,9
< require ‘rails/all’

Pick the frameworks you want:

require “active_record/railtie”

require “action_controller/railtie”
require “action_mailer/railtie”
require “active_resource/railtie”
require “sprockets/railtie”
require “rails/test_unit/railtie”

So, replace the require ‘replace/all’ with a selective require

12c18
< module WithAR

module WithoutAR

this is just the name change (irrelevant)

You will see there are many more interesting options in rails help.

HTH,

Peter
