Module and Test::Unit

Hi,

Is there any way we can use test assertations in a module, or do we
always need to create a test class and inherit test unit?

I am using assertations for GUI tests and have modules with re-usable
methods.

thank you

I'm not sure if this is what you're asking, but I do this sort of thing quite a lot:

module ServiceTests
   def test_foo
     assert @thing.foo
   end
   def test_bar
     assert @thing.bar
   end
end

class RawTests < Test::Unit::TestCase
   include ServiceTests
   def setup
     @thing = Thing.new
   end
end

class XMLRPCTest < Test::Unit::TestCase
   include ServiceTests
   def setup
     client = XMLRPC::Client.new('localhost', '/', $port)
     @thing = client.proxy('thing')
   end
end

That ensures that return values and the like are correct across both native and RPC calls, without overly duplicating code. Is that what you were after?

You can mix in the assertion module even if you are not using
Test::Unit::TestCase. Thus:

module mine
  include Test::Unit::Assertions
  def my_func
    do_something
    assert_equal 2, x
  end
end

The only thing "wrong" with this is that your assertions won't be
counted if this module is actually, later, used by a test case. To fix
that problem, see http://www.io.com/~wazmo/blog/archives/2006_05.html
