Since rspec first appeared on the scene, users have been asking for nested example groups. Well it has finally arrived. RSpec 1.1.0 will ship with support for nesting, so you’ll be able to do things like this:

<code>
describe RSpec do
before(:each) do
  @rspec = RSpec.new
end

describe "at release 1.0.8" do
  before(:each) do
    @rspec.version = "1.0.8"
  end

  it "should not support nested example groups" do
    @rspec.should_not support_nested_example_groups
  end
end

describe "at release 1.1.0" do
  before(:each) do
    @rspec.version = "1.1.0"
  end

  it "should support nested example groups" do
    @rspec.should support_nested_example_groups
  end
end
end
</code>

This will output:

RSpec at release 1.0.8
- should not support nested example groups

RSpec at release 1.1.0
- should support nested example groups

If you’re using trunk, you can do this now with revision 3009 or later.

Happy nesting!
