Pert software testing estimation technique is based on statistical methods in which each testing task is broken down into subtasks, and then three types of estimation are done on each subtasks. Software testing estimation is a management activity to calculate and approximate time, resources and expenses needed to complete test. Cost estimation is a set of techniques and procedures used to arrive at a cost estimate. In some projects, it is possible to know about the size of the system in terms of function points, use case points or lines of code. In order to be a successful in estimating, the software test project and proper execution are significant as the software development life cycle. Firstly unlike traditional methodologies where the qa estimate may be separate to the developer estimate, when working in an agile way you will want your software testing estimates to be combined with your developer estimates, producing one estimate per user story the most common way to do this estimate is using story points where your estimates is a combination of complexity, technical risk.
Other involves consulting the people who will do the work. Ucp method is based on the use cases where we calculate. To achieve bugfree code for your software and mobile applications, software testing estimating techniques should be implemented by your team.
