run rspec tests from specific folder using rake

Question

I wish to use rake to run specific tests in a folder contained withing spec folder. My folder structure is as follows:

- tests
  -spec
   - folder_A
   - folder_B
- rakefile

So for example when certain code is deployed I just wish to run the tests in folder_A. How do I do this using rake? My rakefile lives in my tests folder. I currently have the command:

RSpec::Core::RakeTask.new(:spec)
 task :default => :spec

This runs all tests in the spec folder as you would expect. I have tried moving the rake file into the spec folder and editing the rake task to this:

RSpec::Core::RakeTask.new(:folder_A)
 task :default => :folder_A

However this gives me the message: "No examples matching ./spec{,//*}/*_spec.rb could be found" (note that within folders A and B I have sub directories for the different areas of the application under test)

Is it possible for me to have 2 different rake tasks in the same rakefile that will run the tests just from folder_A?

Any help would be great!!

Why not just use rspec?

rspec spec/folder_A

UPDATED RESPONSE

The :spec in your Rakefile refers to the Rspec rake task, not the folder. You can send options to the task by passing a block as shown on the rake-task doc page

In your case you can pass in a glob for the folder using the pattern option.

RSpec::Core::RakeTask.new(:spec) do |t|
  t.pattern = 'spec/folder_A/*/_spec.rb'
end

For two different rake tasks you'll need to instantiate your RakeTask within each of your own tasks. So your entire Rakefile would look something like this:

require 'rspec/core/rake_task'

task :folder_A do
  RSpec::Core::RakeTask.new(:spec) do |t|
    t.pattern = 'spec/folder_A/*/_spec.rb'
  end
  Rake::Task["spec"].execute
end

task :folder_B do
  RSpec::Core::RakeTask.new(:spec) do |t|
    t.pattern = 'spec/folder_B/*/_spec.rb'
  end
  Rake::Task["spec"].execute
end

task :default do
  RSpec::Core::RakeTask.new(:spec)
  Rake::Task["spec"].execute
end

See the RakeTask doc for details on the pattern method and other options.
