That depends what you mean by "combining those classes into a module".

Do you mean that you want these classes to appear under the MyModule 
namespace? You could simply do:

require 'test'
require 'test1'
module MyModule
  Test = ::Test
  Test1 = ::Test1
end

Now you can use MyModule::Test.new (or whatever)

You still have the top-level constants Test and Test1. You can get rid 
of them using remove_const, although it looks like the class will still 
think its name is "Test" rather than "MyModule::Test"

>> class Test; end
=> nil
>> module MyModule; Test = ::Test; end
=> Test
>> MyModule::Test
=> Test
>> Object.instance_eval { remove_const(:Test) }
=> Test
>> Test
NameError: uninitialized constant Test
  from (irb):8
  from :0
>> MyModule::Test
=> Test
>> 

But at the end of the day, I'd question what it is you're actually 
trying to do. Normally it would make more sense just to add

module MyModule
...
end

to test.rb and test1.rb
