I have finally come up with a workable solution
http://gist.github.com/545866
module MyViewHelper
def tab_for(clazz, &block)
content = with_output_buffer(&block)
content_tag :li, content, :class => clazz
end
end
module MyOtherViewHelper
...
end
describe "do it" do
it "works" do
ActionViewTester.tests MyViewHelper, MyOtherViewHelper
ActionViewTester.new do |helper|
helper.tab_for('kristian') { 'hello' }.should match /kristian/
helper.hello('david') { 'hello' }.should match /david/
end
end
end
