  • 1. Formulating a Test strategyfor an Agile software projectBy Tharinda Liyanage

2. Agenda About QA Some terminology Traditional test practices Formulating a test strategy for the project Iteration metrics 3. Word on QA It is a set of activities intended to ensure that products satisfycustomer requirements in a systematic, reliable fashion. In SCRUM (agile) QA is the responsibility of everyone in R&D,not only the Test team. QA is all the activities we do to ensurecorrect quality during development of new products. 4. Testing terminology Unit testing Automatic test on code level run every night or after new code is added to verify no bugsintroduced Integration testing Testing interactions between different modules of the system Feature testing Performed by a QA when a feature is finished implemented System testing To verify whether the system as a whole meets the specified requirements ExploratoryTesting Exploratory testing is simultaneous learning, test design, and test execution. Regression Testing Test to detect side effects from changes to the system, i.e after bug fix Retesting Verification of bug fix Compatibility testing Verification of compatibility between AMX applications and the different OS, office applications, browsers anddatabases etc that we support 5. How Traditional Test Practices Evolved 6. How Traditional Test Practices Evolved 7. Agile testing We test in iterations Test early Testers take more integrated, team oriented approach than previous 8. Test Strategy-outlined Test strategy in agile developmentReleaseEach Sprint HardeningRelease QA planning(Sprint QA Sprint activities(test plan) activities) (system test) 9. Test Strategy in agile We start our QA activities at Release planning stage Release planning Create test plans High level test planning budgeting enough time Participate in story sizing Typical Test plan will include Scope of testing New functionalities which are being tested Types/ level of testing based on the complexity of the features being tested Performance and load testing Infrastructure consideration (Test environment/software) Risks/ mitigation plans Resourcing Milestones and deliverables 10. Test Strategy in agile Each Sprint Participate in sprint planning Estimate tasks(QA input) Write test cases using stories(QA) High level test cases before coding begins- guide dev Detailed test cases written during coding Unit/ Integration tests(Dev) Automatic test on code level run every night or after new code is added. Bugs found are fixed immediately Pair tests(Dev + QA) Performed when a part of a feature is finished implemented. Bugs found are fixed immediately Feature tests(QA) Performed when a feature is finished implemented. Errors found are logged in main project in bug system and prioritized during next sprint planning. After all prioritized bugs are fixed, the feature is ready for System Test at the end of the project Reviews (stories, req, test cases with customer, programmer) Increase collaboration and communications 11. Test Strategy in agile Each Sprint contd Test automation Automate new functional test cases Run automated regression tests Perform non functional testing (load, security, usability etc) Demo to the stakeholders 12. Test Strategy in agile Hardening sprint A hardening sprint can be used for bug fixes in previous sprints. Bugs that are prioritized will be considered here The end game(System test)Every member in the team is involved in this. Mock deploy on staging Smoke test on staging Perform non functional testing (load, security, usability etc) Complete regression test Perform UAT tests Other tests Compatibility(DB upgrade etc) Installation Localization etc 13. Test Strategy in agile Release Define Exit criteria Testing activities (bug severity, open bugs, coverage levels, metrics etc) Product Artifacts (user guide, installation guides, other necessarydocumentation are in place) Participate in retrospectives Start Stop Continue 14. Iteration metricsTo enhance predictability Measuring progress Burn down charts Estimated vs. Actual time for tasks Defect metrics Root cause analysis Results from defect tracking system Traceability metrics Test coverage (story vs. test cases) Code coverage
