How do I 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 isn't very well-documented; it just says:
- (RakeTask) initialize(*args, &task_block)
A new instance of RakeTask
What should I put for *args and &task_block?
I'm following in the footsteps of someone who had already started to build some ruby automation for a PHP project using RSpec in combination with Rake. I'm used to using RSpec without Rake, so I'm unfamiliar with the syntax.
Thanks,

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 to run specs defined in the spec.rb file from Rake
This 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 tests directory and it will run all tests with a name [something]_spec.rb - and it should work across different test directories (e.g. different projects); if you have source in a separate directory (e.g. in the code above, a subdirectory called '/source' it will pick them up. Obviously, you can change that source directory to what you want.
Here's the rspec_config file I use - you can add your own settings in here:
RSpec.configure do |c|
c.fail_fast = true
c.color = true
end

We have developed few test cases using mini-test / ruby
Now we are trying to run it using rake files.
its working fine if we are running below code.
require 'rake'
require 'rake/testtask'
Rake::TestTask.new do |t|
t.test_files = FileList['../Home/*TC1.rb']
t.verbose = true
end
But we are putting the above code in separate task then id does not run the test
task :myCustom_task do
Rake::TestTask.new do |t|
t.test_files = FileList['../Home/*TC1.rb']
t.verbose = true
end
end
Then we run it by below command
rake myCustom_task
and it does not run the test.Also it does not show any error while running with --trace option.
What is missing in this approach ?
I have a file containing a class of multiple tests (using minitest). I have require 'minitest/autorun' at the top of the file and all tests run correctly when I call the file directly (ruby my_tests.rb).
So far, so good. However, now I'm trying to run my tests via rake.
require "rake/testtask"
task :default => [:test]
Rake::TestTask.new do |t|
t.libs << Dir.pwd + "/lib/examples"
t.test_files = FileList['test/test*.rb']
end
Calling rake shows test/my_test.rb getting called but no tests within the class get run (0 tests, 0 assertions, etc.). I do get these warnings:
...gems/minitest-5.8.0/lib/minitest/assertions.rb:17: warning: already initialized constant MiniTest::Assertions::UNDEFINED
...ruby/2.1.0/lib/ruby/2.1.0/minitest/unit.rb:80: warning: previous definition of UNDEFINED was here
How can I run my tests within rake successfully? I am not using rails.
EDIT: Here is the top of my test file:
require 'minitest/spec'
require 'minitest/autorun'
require 'minitest/reporters'
reporter_options = { color: true }
Minitest::Reporters.use![Minitest::Reporters::DefaultReporter.new(reporter_options)]
class Test_PowerSpecInputs < Minitest::Test
def setup
#mc = TestClass.new()
end
def test_does_lib_have_constant
# my test code
end
end
Try changing your Rakefile to this.
require "bundler/gem_tasks"
require "rake/testtask"
Rake::TestTask.new(:test) do |t|
t.libs << "test"
t.libs << "lib"
t.test_files = FileList['test/**/*_test.rb']
end
task :default => :test
jphager2 got me thinking about tool versions and it turned out that my version of rake was fairly old. Updating to 11.x did the trick.
I'm setting up a new Sinatra app and am having issues getting my tests to run via a rake task. When I run rake:test, the task runs, shows me which files it will be running, but nothing happens. I know it's loading the class because it has failed due to syntax errors, but I never see my tests running. What am I missing? Below is my configuration and example test:
rakefile.rb
require "rake/testtask"
require "sinatra/activerecord/rake"
require "./app"
task :default => :test
TEST_FILES = FileList["test/**/test*.rb"]
desc "Run all of the tests for redFish"
Rake::TestTask.new do |t|
t.libs << "test"
t.test_files = TEST_FILES
t.verbose = true
end
task :default => "test"
test/test_helper.rb
ENV["RACK_ENV"] = "test"
require "rack/test"
require "awesome_print"
require "active_support"
require "active_support/core_ext"
/test/unit/test_organization.rb
require File.expand_path '../../test_helper.rb',__FILE__
class TestOrganization < ActiveSupport::TestCase
def setup
puts "setup for tests"
end
test "validates_required_fields" do
puts "RUNNING TESTS"
assert true
refute false
end
end
When I run rake:test, I can see that test_helper and test_organization.rb are being found by the TestTask, but I don't see any tests pass/fail.
Am I missing something obvious?
Looks like the issue was caused by not requiring minitest/autorun in my test helper. I added that line, and the tests ran fine.
I have a very simple Rakefile to test a small Ruby gem. It looks like this:
Rake::TestTask.new
task :default => :test
It invokes two tests that define constants with the same name. This results in errors being output by the second test like this:
warning: already initialized constant xxxxx
The reason for this is because Rake executes all of the tests within a single Ruby instance:
/usr/bin/ruby -I"lib" -I"/usr/lib/ruby/gems/2.1.0/gems/rake-10.3.2/lib" "/usr/lib/ruby/gems/2.1.0/gems/rake-10.3.2/lib/rake/rake_test_loader.rb" "test/test*.rb"
How should I specify that each test should be run in a separate Ruby instance ?
I have achieved this as shown below but I wonder if there is a better way because this solution doesn't scale well for lots of tests.
Rake::TestTask.new(:one) { |t| t.test_files = %w(test/test_one.rb) }
Rake::TestTask.new(:two) { |t| t.test_files = %w(test/test_two.rb) }
task :default => [:one, :two]
Instead of using Rake::TestTask, you could define a test task in your Rakefile that loops through each test file and runs them with sh like this:
task :test do
libs = ['lib',
'/usr/lib/ruby/gems/2.1.0/gems/rake-10.3.2/lib',
'/usr/lib/ruby/gems/2.1.0/gems/rake-10.3.2/lib/rake/rake_test_loader.rb']
test_files = FileList['test/**/test*.rb']
test_files.each do |test_file|
includes = libs.map { |l| "-I#{l}"}.join ' '
sh "ruby #{includes} #{test_file}"
end
end
I have the following Rakefile in a Ruby 1.9.3 project:
require 'rake/testtask'
require 'json'
Rake::TestTask.new do |t|
t.pattern = "spec/**/*_spec.rb"
t.verbose = true
end
task :default => :test
namespace :omglol do
namespace :file_a do
task :foo do
# do some stuff
end
end
namespace :file_b do
task :bar do
# do some stuff
end
end
end
As you can see, the first part of this file allow to run tests, just using rake command. And the second part contains some tasks.
Actually, I have a lot of tasks inside omglol:file_a and omglol:file_b namespaces. That's why I would like to move each of them inside a file, for instance tasks/omglol/file_a.rake and tasks/omglol/file_b.rake.
Is there a best way to do so? Thanks.
Yes. Simply move the logic into the appropriate files and then require them.
Example Rakefile:
require 'rake/testtask'
require 'json'
require 'lib/tasks/omglol/file_a.rake' # <= contains your subtasks
Rake::TestTask.new do |t|
t.pattern = "spec/**/*_spec.rb"
t.verbose = true
end
task :default => :test
Then in lib/tasks/omglol/file_a.rake simply define your tasks as normal:
namespace :omglol do
namespace :file_a do
task :foo do
# do some stuff
end
end
end
The pattern would be the same for file_b.rake.
