How to create RSpec Rake task using RSpec :: Core :: RakeTask?

How to initialize an RSpec Rake task using RSpec :: Core :: RakeTask?

  require 'rspec / core / rake_task'

 RSpec :: Core :: RakeTask.new do | t |
   # what do I put in here?
 end

The Initialize function, documented at http://rubydoc.info/github/rspec/rspec-core/RSpec/Core/RakeTask#initialize-instance_method, is not very well documented; he just says:

  - (RakeTask) initialize (* args, & task_block)

 A new instance of RakeTask

What should I put for * args and & task_block?

I am following in the footsteps of someone who has already started building some ruby ​​automation for a PHP project using RSpec in combination with Rake. I'm used to using RSpec without Rake, so I'm not familiar with the syntax.

Thanks Kevin

Here is an example of my Rakefile:

require 'rspec/core/rake_task' task :default => [:spec] desc "Run the specs." RSpec::Core::RakeTask.new do |t| t.pattern = "spec.rb" end desc "Run the specs whenever a relevant file changes." task :watch do system "watchr watch.rb" end

This allows you to run the specifications defined in spec.rb from Rake

Here is what my rakefile looks like

 gem 'rspec', '~>3' require 'rspec/core/rake_task' task :default => :spec desc "run tests for this app" RSpec::Core::RakeTask.new do |task| test_dir = Rake.application.original_dir task.pattern = "#{test_dir}/*_spec.rb" task.rspec_opts = [ "-I#{test_dir}", "-I#{test_dir}/source", '-f documentation', '-r ./rspec_config'] task.verbose = false end

You can "rake" from your test directory, and it will run all the tests with the name [something] _spec.rb - and it should work in different test directories (for example, in different projects); if you have the source in a separate directory (for example, in the code above, a subdirectory called "/ source", it will pick them up. Obviously, you can change this source directory to whatever you want.

Here's the rspec_config file I'm using, you can add your own settings here:

 RSpec.configure do |c| c.fail_fast = true c.color = true end
