Rakefile not calling default task

Question

I am trying my hand at writing a rakefile, and have what I think should call simplecov and then call rspec to run tests, but when I run my rakefile nothing gets executed. Am I doing something wrong? Also, is there a way to give the :spec task a dependency, I want it to call :simplecov before it executes.

require 'rake'

task :coverage do
  require 'simplecov'
  SimpleCov.start 'rails'
end

require 'rspec/core/rake_task'
RSpec::Core::RakeTask.new(:spec)

task :default => [:coverage, :spec]

Answer 1

Unfortunately default can only have one task but you're welcome to use a namespace to package tasks together. Yours might look like:

require 'rake'

namespace :rspec_cov do
  task :coverage do
    require 'simplecov'
    SimpleCov.start 'rails'
  end

  task :spec do
    sh 'bundle exec rspec'
  end
end

task :testing => ["rspec_cov:coverage", "rspec_cov:spec"]

now running rake testing will run both those tasks as you wanted. On a totally separate note, if you receive an exit code issue (like I did) there seems to be a bug in SimpleCov that they're working on (issue here).
