obj.meth = x always returns x, regardless of what the method would  
return in normal circumstances. You should test like this:

@prj.proj = '68906'

assert_equal( '068906', @prj.proj )


% cat assigns.rb
class A
   def f=(x)
     false
   end
end

a = A.new
p a
p( a.f = 22 )

% ruby assigns.rb
#<A:0x1e9328>
22
