13 BSE Testing philosophy Robust testing Faster time to market Standard testing across applications Ensure all stakeholder participation

14 Testing process 4 tier testing • Development • User Application Testing • Quality Assurance • Marketwide Mock Testing environments • Development • UAT • Simulation – available to members 24x7 for testing patches • Internal Lab – for internal system and application testing and tuning • Algo Test Lab on cloud – members can test algo strategies

15 Testing process Testing tools • Load simulator • Automated testing Type of testing • Black-box testing (functional) • Regression testing • Sanity testing • Negative testing • GUI testing

16 Testing approach Development team • Design document/ Implementation approach shared with UAT and QA teams • Knowledge transfer session conducted for UAT and QA teams UAT and QA teams • Preparation of test plans, test scenarios, test cases • Observations/Defects reported in Reporting system Redmine • Review discussions of reported observations/defects with Dev team • Re-testing of observations once fixed by development team • Sign-off by both teams after completion of testing • One round of testing conducted in the production environment during mock trading session

17 QA Testing approach • Agile methodology - reduces the testing and release to the market time • Test complete system v/s only the functions • Automated testing for the applications to do regression testing which ensures complete coverage (Qualitia Product with underlining tool QTP and Selenium) • Release Management tool like SVN ensures the correct code is migrated to the production setup
