Rails: How to test code in the lib/ directory?

Question

I have a model which gets its data from a parser object. I\'m thinking that the parser class should live in the lib/ directory (although I could be persuaded that it should live

Answer 1

Here's one way:

Create lib/tasks/test_lib_dir.rake with the following

namespace :test do

  desc "Test lib source"
  Rake::TestTask.new(:lib) do |t|    
    t.libs << "test"
    t.pattern = 'test/lib/**/*_test.rb'
    t.verbose = true    
  end

end

Mimic the structure of your lib dir under the test dir, replacing lib code with corresponding tests.

Run rake test:lib to run your lib tests.

If you want all tests to run when you invoke rake test, you could add the following to your new rake file.

lib_task = Rake::Task["test:lib"]
test_task = Rake::Task[:test]
test_task.enhance { lib_task.invoke }
