How to write cucumber test case in RAILS 3
Answer is here just follow all my steps...
Step 1:
To write cucumber test case we need to include the following gem in Gemfile
group :test do
gem 'cucumber-rails'
gem 'database_cleaner
end
Note: database_cleaner gem is used to cleaner the dummy data that we use for testing
Step 2:
Now to time to generate cucumber by following command
In your terminal type this command
rails g cucumber:install
Step 3:
Now we can see features folder in your application
In the folder we can write your own Scenario of the controller or action document in features folder with name related to your controller
for example
if you going to write test case for login then use Login.feature
then save it in features/Login.feature (In this blog in use Login.feature for sample)
Step 4:
In previous version of rails the web_steps.rb,paths.rb and selectors.rb will automatically generated but in rails 3 we have to create or get download from following links
download all above three file and put in features/support folder replace env.rb also
download the above web_steps file and put in to features/step_definitions folder
Note: Web_steps.rb file is common to all the test case (only common function will be there)
Step 5:
Now time to run your test case by using below command
bundle exec cucumber features/filename.feature
If you want to run all the test case using one command
rake cucumber
step 6:
If you want to generate pdf for all test case you have to follow this steps
first install
gem 'prawn'
then use this command
bundle exec cucumber --f pdf --out sample_pdf features/file.name.features
(it is single line command so copy fully and use it)
Note :sample_pdf ---->output pdf file name
I here give you the sample cucumber test case for your reference
download above file and put it in features folder
download above file and put it in step_definitions folder
Note :This is used for specifying the path of the action
