Software estimation techniques there are different software testing estimation techniques which can be used for estimating a task. The most popular software testing estimation techniques. Software testing estimation ste can be defined as the management of activity that calculates a rough estimation of how long a task or work or test will take in completing. Estimation is needed to avoid exceeding the timescale and over passing the budget for testing activities. In recent years, different techniques, tools and methods have been developed for this very purpose.
If you correctly estimate your project, it will help you to test the software with maximum exposure. Test estimation techniques are an exercise of evaluating the effort to complete the testing. Test estimation plays an important role throughout the software testing life cycle. It helps the project manager to further predict the effort and time which will be needed to build the project. This online video tutorial is specially designed for beginners with little or no manual testing experience. Before starts the testing activity, test estimation is calculated to plan the testing. So the various factors in use case give a direct proportion to the testing effort.
