Rails - Aug 2007 - Testing library code

Hi,

Just a quick question: If one creates custom classes and modules and
places them in the lib/ folder of rails, where should the tests for
those classes/modules go? Are they just unit tests?

Thanks,
Toby

Well it is just ruby code so you can make a small ruby application and 
test it that way, and you can do it with test too I presume.

What I mean is that I would like to use test::unit to test my modules
and classes but I''m not sure where to put the test I write in the
directory structure of rails. Some of my controllers rely on these
modules/classes so they require testing, I''m just not sure how to go
about it.

I tend to think of them as part of my unit tests
(that is the way they generally get used)

If you want to put in a bit of work, you could very easily add a 
/test/lib directory
and define a "test:libs" rake command.

namespace :test do
    Rake::TestTask.new(:libs => "db:test:prepare") do |t|
        t.libs << "test"
        t.pattern = ''test/lib/**/*_test.rb''
        t.verbose = true
    end
    Rake::Task[''test:libs''].comment = "Run the lib tests
in test/lib"
end

stick that in a file in lib/tasks

you''d then want to overwrite the default test task, like so...

desc ''Test all units and functionals''
task :test do
  exceptions = ["test:units", "test:libs",
"test:functionals",
"test:integration"].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

(note: all of the code above is made from just small changes to the 
default tasks, found inside the rails gem -- 
/rails/lib/tasks/testing.rake

Put all unit-level tests in test/unit.

The meaning of "unit test" isn''t "model test";
it''s generally the low-level
tests.

If you don''t want to run too many tests between each edit, google for 
"test:svn_modified" and use that to trigger only the tests files you
changed
since your last integration.
