In RSpec&#39;s new expectation syntax, you would express it as:


    expect(target).to be &lt; 6

This is still the accepted way to handle this test.  It&#39;s best to use &gt;, &lt;, and == in my opinion for numerical comparisons -- it&#39;s clearer.

If you just want to check it in a variable like `target` then `target.should be &lt; 6` is the way to go.

But if you want to check a property in another object, like `customer.orders`, where orders is a collection of elements, then you could use the [have(n).items matcher](https://www.relishapp.com/rspec/rspec-expectations/v/2-13/docs/built-in-matchers/have-n-items-matcher).

Example:

    customer.should have_at_most(6).orders

That is the same expectation than this:

    customer.orders.size.should be &lt; 6

But with a cleaner message

I want to differentiate the STDOUT and STDERR messages in my terminal.
If a script or command is printing a message in terminal I want to differentiate by colors; is it possible?

(E.g. stderr font color is red, and stdout font color is blue.)

Example (using bold):

&gt; `$date`  
&gt; `Wed Jul 27 12:36:50 IST 2011`
&gt;
&gt; `$datee`  
&gt; **`bash: datee: command not found`**
&gt;
&gt; `$alias ls`  
&gt; `alias ls=&#39;ls --color=auto -F&#39;`
&gt;
&gt; `$aliass ls`  
&gt; **`bash: aliass: command not found`**

I have a project that has one target dependency. The target dependency is dependent on a framework called Three20. 

The dependency tree looks like this.

    myProject
       -&gt; myCustomFramework
             -&gt; Three20

When I tried to build and run I get the following error message. 

&gt; Workspace Integrity Couldn&#39;t load Three20.xcodeproj because it is
&gt; already opened from another projet or workspace.

I have only one project open. Any suggestions on why I am getting this message?

http://cheat.errtheblog.com/s/rspec/ has for inequalities (such as less than or greater than)

    target.should be &lt; 6

Has anything better been created since the cheat sheet was created?

Does rspec have anything more specific than target.should be &lt; 6?

In regards to adding an `key =&gt; value` pair to an existing populated hash in Ruby,  I&#39;m in the process of working through Apress&#39; Beginning Ruby and have just finished the hashes chapter.

I am trying to find  the simplest way to achieve the same results with hashes as this does with arrays:

    x &lt;&lt; 5

I am using Ruby on Rails 3.0.9 and I would like to check if a number is included in a range. That is, if I have a variable `number = 5` I would like to check `1 &lt;= number &lt;= 10` and retrieve a boolean value if the `number` value is included in that range.

I can do that like this:

    number &gt;= 1 &amp;&amp; number &lt;= 10

but I would like to do that in one statement. How can I do that?

Could anyone explain `params` in Rails controller: where they come from, and what they are referencing?

      def create

        uid = params[:vote][:user_id]
        @extant = Vote.find(:last, :conditions =&gt; [&quot;item_id = ? AND user_id = ?&quot;, item, uid])
        last_vote_time = @extant.created_at unless @extant.blank?
        curr_time = Time.now
      end

I would like to be able to read this code line-by-line and understand what&#39;s going on.

I am building up an integration test suite and there is one bit of logic that I need to have a clean database for. How can I run the `db:test:purge` task inside of one of my tests?

I am using: ruby 1.9.2, rails 3.0.9, rspec 2.6

One (or a couple) of our tests are taking forever and we&#39;d like to optimize them.

Is there an easy to way to find the slow ones?

Can someone tell me if I&#39;m just going about the setup the wrong way?

I have the following models that have has_many.through associations:

    class Listing &lt; ActiveRecord::Base
      attr_accessible ... 

      has_many :listing_features
      has_many :features, :through =&gt; :listing_features
  
      validates_presence_of ...
      ...  
    end


    class Feature &lt; ActiveRecord::Base
      attr_accessible ...
  
      validates_presence_of ...
      validates_uniqueness_of ...
  
      has_many :listing_features
      has_many :listings, :through =&gt; :listing_features
    end


    class ListingFeature &lt; ActiveRecord::Base
      attr_accessible :feature_id, :listing_id

      belongs_to :feature  
      belongs_to :listing
    end


I&#39;m using Rails 3.1.rc4, FactoryGirl 2.0.2, factory_girl_rails 1.1.0, and rspec.  Here is my basic rspec rspec sanity check for the `:listing` factory:

    it &quot;creates a valid listing from factory&quot; do
      Factory(:listing).should be_valid
    end

Here is Factory(:listing)

    FactoryGirl.define do
      factory :listing do
        headline    &#39;headline&#39;
        home_desc   &#39;this is the home description&#39;
        association :user, :factory =&gt; :user
        association :layout, :factory =&gt; :layout
        association :features, :factory =&gt; :feature
      end
    end
    

The `:listing_feature` and `:feature` factories are similarly setup.  
If the `association :features` line is commented out, then all my tests pass.  
When it is 

    association :features, :factory =&gt; :feature

the error message is 
`undefined method &#39;each&#39; for #&lt;Feature&gt;`  which I thought made sense to me because because `listing.features` returns an array.  So I changed it to 

    association :features, [:factory =&gt; :feature]

and the error I get now is `ArgumentError: Not registered: features`  Is it just not sensible to be generating factory objects this way, or what am I missing?  Thanks very much for any and all input!

I have been googling for about 90 minutes now and still don&#39;t have an answer to this.  Where do I set `default_url_options`?  I&#39;ve already set it for `config.action_mailer.default_url_options` to solve this same bug elsewhere, but now I&#39;m getting this error when trying to use a URL helper inside an RSpec spec.  I have no idea where it&#39;s expecting default_url_options to be set.

     Failure/Error: listing_url(listing).should match(/\/\d+-\w+$/)
     RuntimeError:
       Missing host to link to! Please provide :host parameter or set default_url_options[:host]
     # ./spec/routing/listing_routing_spec.rb:9:in `block (3 levels) in &lt;top (required)&gt;&#39;

This code has nothing to do with emails/ActionMailer, it just happens to need a URL instead of a path.

Any ideas?

I am needing to stub the response of a `current_user` method in an Rspec/capybara request spec. The method is defined in `ApplicationController` and is using helper_method. The method should simply return a user id. Within the test, I&#39;d like this method to return the same user id each time. 

Alternatively, I could fix my problem by setting `session[:user_id]` in the spec (which is what `current_user` returns)... but that doesn&#39;t seem to work either. 

Are either of these possible?

Edit:

Here is what I&#39;ve got (it is not working. It just runs the normal current_user method).


    require &#39;spec_helper&#39;

    describe &quot;Login&quot; do
  
       before(:each) do
         ApplicationController.stub(:current_user).and_return(User.first)
       end
  
      it &quot;logs in&quot; do
        visit &#39;/&#39;
        page.should have_content(&quot;Hey there user!&quot;)
      end
  
    end


Also not working:

    require &#39;spec_helper&#39;

    describe &quot;Login&quot; do
  
      before(:each) do
        @mock_controller = mock(&quot;ApplicationController&quot;) 
        @mock_controller.stub(:current_user).and_return(User.first)
      end

      it &quot;logs in&quot; do
        visit &#39;/&#39;
        page.should have_content(&quot;Hey there user!&quot;)
      end
  
    end
