Well, you've almost nothing to do:

before(:each) do
  @meth = :abc

  request.env['HTTP_USER_AGENT'] = "..."
end

I just gave this another try and this passes:

#in helper
def foo
  request.env['HTTP_USER_AGENT']
end

#spec
it "foo" do
  helper.request.env['HTTP_USER_AGENT'] = 'foo'
  expect(helper.foo).to eq 'foo'
end
