Module and Test::Unit

Ruby
1

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 404 Error - Page Not Found...
