Although there are a number of QA methodologies which software project teams could adopt, the choice primarily depends on the type of project. If clients are able to provide all requirements in the first phase itself, then the natural choice is the waterfall methodology. The waterfall methodology is very efficient in developing software products when all requirements are promptly supplied by clients.
But there are teams that work on requirements that keep changing constantly. For such teams iterative models are adopted. For teams working on iterative models, they require an efficient testing tool to get the testing activity done on time. The tool must be able to support multiple test cases management, testing metrics, testing dashboards, easy defect tracking mechanisms etc.
