Performance Testing of Rich Internet Applications & Web applications UKTMF summit 2009
Overcoming 2009 Challenges for load testing web applications • Respond successfully to business pressure “do more with less” • Test increasingly complex web applications: AJAX, Silverlight, FLEX (amf3), GWT (google web toolkit), SAP Web, Oracle Forms, Siebel Web, Oracle E-business, OBI, JD Edwards, PeopleSoft, Hyperion, ……
Respondsuccessfully to business pressure • Economically: Complete more tests and be more cost effective • Points you can have an impact on: - Flexibility of your load testing software - Time required to execute the entire engagement
Respondsuccessfully to business pressure • Strategically: • Webapps are increasingly important within companies • Do it in a shorter time frame for your SLA and a shorter time to market • Maintain scenarios and compare performance of new releases
Respond successfully to business pressure • Technologically • use a modern tool • Made for web applications • Supports the latest technologies: PoC & advices, sizing of infrastructure when addressing new needs arising from evolving development frameworks • Handle the latest webapps just as easily as older/simpler ones
Reduce the cost of your load testing platform Increaseyourproductivity: Use modern tools adapted to today’s web applications to get a better ROI: • Easy and fast to install on any platform • Scenarios are faster to create & maintain • Efficient to generate the required load • Precise monitoring and reporting
Time allocation for your engagments Time spent Older tool Recent tool
Reduce the cost of your Load Testing platform - Know the alternatives to better allocate your value adding ressources • Retain your testers with a wider scope during the assignements (less scripting & more analysis) • More time to test, to give better recommandations & reports = maximise value to your client
Load test the latest web applications • What’s a RIA ? Definition : a Rich Internet Application is capable of delivering a rich experience to the user: • More connected • More interactive • More intuitive • What technologies are used ? AJAX based frameworks, FLEX, AIR, Silverlight, GWT, etc…
Challenges for Testing RIA (1/4) • Faster development of webapps = Faster Testing required • More complex test cases due to increased user interactions • Browser server interactions are different from standard webapps which impacts the behavior of servers
Challenges for testing RIA (2/4) • Manage specific formats encapsulated in HTTP requests • Example for Flex content with AMF binary messages:
Challenges for testing RIA (3/4) • A highernumber of asynchronous requests to deal with • Switch fromparrallel to sequential mode for the requests of a page • A higher number of dynamic parameters • Need to be able to definecomplexcorrelation « rules » to automate the future design of your scenarios
Challenges for testing RIA (4/4) • Specific behaviour to take into account : • Polling: Involving the browser to query the server at regular intervals • Streaming (or « push »): the client sends a single request to the server and the server responds each time a pertinent information is available
Challenges for Testing Complex Web Applications • Oracle E-Business Suite • Oracle Forms: handling the protocol + recent HTTP/S portal • Siebel Web • Complex HTTP/S with numerous dynamic parameters, specific format & AJAX • SAP Web • Numerous dynamic parameters
mandotory elements to look for in a load testing tool to : Produce a realistic test • Script all major test cases • Variable extractor • Response validation • Advanced Variable managment • Realistic load policy • Errors managment
Mandotory elements to look for in a load testing tool to : Make your results talk to: • Know where your bottlenecks are • Must employ advanced monitoring for: • O/S • DB • Application Server • Builld useful graphs and reports • Compare results with SLA and/or Reference tests • Take corrective actions
A few best practices • Tips to take home to test your web applications • Test earlier in the development process • Test each new release and compare with previous • Start your test campaign with solid test plan • Spend time on what is the most important • Produce report understandable by all
