HBT Stage 5 (Tooling) Key focus: STEM discipline D5(Tooling) Problems addressed: • Organization is not sure on which tool they should make investment • Functional test or non-functional test or both? What to automate? • We have so many test cases. Where to start focusing on automation? • We had excellent automation team who did some automation but not working on latest version of product but no band width to look at it • We have legacy tool used for automation it is not supported by vendor anymore. Can we port it to another tool? • Open source / commercial tools? Which will fit our automation strategy? • Can you help us accelerate our automation project? • Many things automated but product quality is still a concern! Copyright 2011. STAG Software Pvt Ltd.
