I tried "features/task_spect.rb" and "requests/tasks_spect.rb"

require "rails_helper"
    RSpec.describe "Tasks", type: :request do
      describe "GET /tasks" do
        it "display some task" do
            @task = Task.create :task => "go to bed"
            visit tasks_path
            page.should have_content "go to bed"

        end
        it "creates a new task" do
            visit "/"
            fill_in "Task", :with => "go to work"
            click_button "Create Task"

            current_path.should == root_path
            page.should have_content "go to work"

            save_and_open_page

Deprecation Warnings:

Requiring `rspec/autorun` when running RSpec via the `rspec` command is deprecated. Called from /home/rajarshi/.rbenv/versions/2.1.4/lib/ruby/gems/2.1.0/gems/activesupport-4.1.8/lib/active_support/dependencies.rb:247:in `require'.

Using `should` from rspec-expectations' old `:should` syntax without explicitly enabling the syntax is deprecated. Use the new `:expect` syntax or explicitly enable `:should` with `config.expect_with(:rspec) { |c| c.syntax = :should }` instead. Called from /home/rajarshi/tasks/spec/features/task_spec.rb:18:in `block (3 levels) in <top (required)>'.


If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.
