    I solved this issue – at first I was adding gems in enviorement/tests.rb but after adding those gems in gemfile – problem get solved.
    this is the step-

    in gemfile

    group :development, :test do
  #gem "rspec-rails", '>=1.3.2'
  gem 'rspec', '>=1.3.2'
  gem "capybara", "0.3.9"
  gem "cucumber", ">=0.2.2"
  gem "cucumber-rails", "0.3.2" 
  gem 'database_cleaner'
  gem 'webrat', ">=0.4.3"
end

    from project folder console/terminal run this command => ruby script/generate cucumber
