In your test code do:

class ClassUnderTest
  public :private_method1, :private_method2 # ...
end

as exemplified by:

feldt:~$ irb
irb(main):001:0> class T
irb(main):002:1> private
irb(main):003:1> def a; 1; end
irb(main):004:1> end
=> nil
irb(main):005:0> t = T.new
=> #<T:0xb7db90a8>
irb(main):006:0> t.a
NoMethodError: private method `a' called for #<T:0xb7db90a8>
        from (irb):6
        from :0
irb(main):007:0> class T
irb(main):008:1>  public :a
irb(main):009:1> end
=> T
irb(main):010:0> t.a
=> 1
irb(main):011:0>
