Question: what is defect tracting tools and how they are used in software testing? 

Answer: A bugtracker is a ticket tracking system that is designed especially to manage problems (software bugs) with computer programs.\n\nTypically bug tracking software allows the user to quickly enter bugs and search on them. In addition some allow users to specify a workflow for a bug that automates a bug's lifecycle.\n\nMost bug tracking software allows the administrator of the system to configure what fields are included on a bug.\n\nHaving a bug tracking solution is critical for most systems. Without a good bug tracking solution bugs will eventually get lost or poorly prioritized.\n\nDirectory for Software Development\nThe most useful links to\nDefect Tracking Tools Sites  provided by\n\nQ-Success \n 95 Hand-picked Defect Tracking Tools Sites \n\n\nclick here for further details:\n\nhttp://www.software-pointers.com/en-defecttracking-tools.html
