How to test JavaScripts without deleting the database data `test`?

Question

I am using Ruby on Rails 3.2.2, cucumber-rails-1.3.0, rspec-rails-2.8.1 and capybara-1.1.2. I would like to use Selenium to test JavaScripts, but without deleting the test database data every time I run cucumber in a terminal window. That is, if I specify a function such as:

 Feature: ... @javascript Scenario: ... 

JavaScript is being tested as expected. However, after starting the test, the test database data is deleted, and I have to start this database again to run the new tests correctly.

I read the Official documentation and the text present in the file ROOT_APP/features/support/env.rb (it seems that I have installed all the necessary Ruby jewelry - see below for more information on the Gemfile that I use), but I did not understand how to avoid deleting database data and how to configure Cucumber and Capybara stones to work correctly with Selenium.

What should I do?

Note I: I would like to do the above because I would like to have the same test database data when I “tested” / “ran” the scripts.

Note II To sow data in the test database (my application needs this data to work), I add the following code to the file RAILS_ROOT_PATH/lib/tasks/cucumber.rake , and I run the rake db:test:prepare command line from the terminal window.

 namespace :db do namespace :test do task :prepare => :environment do Rake::Task["db:seed"].invoke end end end

In the ROOT_APP/features/support/env.rb I tried to uncomment one and both of the following blocks of code (BTW: I never changed the source file automatically generated by the cucumber-rails stone, so it is standard), but after the tests run it still deletes test database data.

 # Before('@no-txn,@selenium,@culerity,@celerity,@javascript') do # # { :except => [:widgets] } may not do what you expect here # # as tCucumber::Rails::Database.javascript_strategy overrides # # this setting. # DatabaseCleaner.strategy = :truncation # end # # Before(' ~@no-txn ', ' ~@selenium ', ' ~@culerity ', ' ~@celerity ', ' ~@javascript ') do # DatabaseCleaner.strategy = :transaction # end 

---

Excerpt from the Gemfile:

 group :development, :test do gem "rspec-rails" end group :test do gem 'cucumber-rails' gem 'database_cleaner' gem 'capybara' end

I ran into this problem and was able to fix it by changing the following line to ROOT_APP/features/support/env.rb

from

 Cucumber::Rails::Database.javascript_strategy = :truncation 

to

 Cucumber::Rails::Database.javascript_strategy = :transaction 

Hope this helps ...
