Rake Test Without Migrations

I had to modify rake test to run tests without migration dependencies. My script after modification looked as following:

desc 'Test all units and functionals'
task :run_customized_test do
  exceptions = ["custom_test:units","custom_test:functionals","custom_test:integration","custom_test:rcov"].collect do |task|
    begin
      Rake::Task[task].invoke
      nil
    rescue => e
      e
    end
  end.compact

  exceptions.each {|e| puts e;puts e.backtrace }
  raise "Test failures" unless exceptions.empty?
end

namespace :custom_test do
  #UNITS
  Rake::TestTask.new(:units) do |t|
    t.libs << "test" 
    t.pattern = 'test/unit/**/*_test.rb'
    t.verbose = true
  end
  Rake::Task['custom_test:units'].comment = "Run the unit tests in test/unit without migrations" 
  #FUNCTIONALS
  Rake::TestTask.new(:functionals) do |t|
    t.libs << "test" 
    t.pattern = 'test/functional/**/*_test.rb'
    t.verbose = true
  end
  Rake::Task['custom_test:functionals'].comment = "Run the functional tests in test/functional without migrations" 
  #INTEGRATION
  Rake::TestTask.new(:integration) do |t|
    t.libs << "test" 
    t.pattern = 'test/integration/**/*_test.rb'
    t.verbose = true
  end
  Rake::Task['custom_test:integration'].comment = "Run the integration tests in test/integration without migrations" 
  #This task was redesigned by my coworker Krishna Kotecha
  desc  "Run the ruby coverrage for your project" 
  task :rcov do
    output_folder = "." 
    rm_f output_folder
    rm_f "coverage.data" 
    rcov = "rcov --rails --aggregate coverage.data --text-summary -Ilib" 
    system("#{rcov} --no-html test/unit/*_test.rb")
    system("#{rcov} --no-html test/unit/helpers/*_test.rb")
    system("#{rcov} --no-html test/functional/*_test.rb")
    system("#{rcov} --output=#{output_folder} --sort=coverage --html test/integration/*_test.rb")
  end
end

Also, there is an rcov taks wich will generate ruby coverage and store it in public folder under ProjectName folder. This task is customized for cc.rb you might need to change the path.
