Most applications when pushed to production are not found to be tested properly for all possible situations leading to disruptions in user experience, unwanted results and missing features. To avoid a bad user experience, revenue loss, resource wastage, lost opportunity cost and delayed release, enterprises need to consider end-to-end QA functional testing.



GTS Functional Software Testing approach is designed and implemented for each project based on the domain and technical requirements to ensure that each project requirement is addressed in a specific manner. This framework adopts requirement specifications, business logic flow and risk based approaches, to ensure test coverage and quality.
