Defining the Net Class

Lets define the Net class now. We open a file named 'net.rb' and enter the following code ... 

# file: net.rb
class Net
end

And don't forget to add the proper require line to our test program. 

# file: testnet.rb
require 'test/unit'
require 'net'
...

And try our test again ...

  
$ ruby testnet.rb
Loaded suite testnet
Started...
..
Error occurred in test_untied(TestNet): NameError: undefined method `untied?' for #<Net:0x40216a60>
	testnet.rb:7:in `test_untied'
	testnet.rb:5

Finished in 0.051946 seconds.
1 runs, 0 assertions, 0 failures, 1 errors

Now the test is complaining that the method untied? is not defined. It looks like our next job is to write a new method.
