This is an early preview of Stella. The following features are still under development (as of 2009-09-15):
-
Reporting of any kind.

Documentation.
# Verify a test plan is defined correctly # by running a single user functional test. $ stella verify -p examples/basic/plan.rb http://stellaaahhhh.com/ # Generate load using the same test plan. $ stella generate -p examples/basic/plan.rb -c 50 http://stellaaahhhh.com/
Test plans are defined in the Ruby programming language. This makes it possible to define sophisticated logic to handle responses. They also typically contain more than one usecase which is important when simulating realistic load. In this example, 65% of virtual users will execute the first usecase and 35% will execute the second.
usecase 65, "Simple search" do get "/", "Homepage" do wait 1..5 response 200 do status # => 200 headers['Content-Type'] # => ['text/html'] body # => <html>... doc # => Nokigiri::HTML::Document end end get "/search", "Search Results" do wait 2..5 param :what => 'Sarsaparilla' param :where => 'Lexington' response 200 do listing = doc.css('div.listing').first set :lid, listing['id'].match(/(\d+)/)[0] end end get "/listing/:lid" do # URIs can contain variables. desc "Selected listing" # This one will be replaced by wait 1..8 # the one stored in the previous end # request. end usecase 35, "YAML API" do resource :listing_ids, list('ids.csv') get "/listing/:lid.yaml" do desc "Select listing" param :lid => random(:listing_ids) response 200 do repeat 5 end end end
