It is created by breaking down the test project into small pieces. Modules are divided into sub-modules. Sub modules are further divided into functionality and functionalities are divided in sub-functionalities.

Review all the requirements from Requirement Document to make sure they are added in Work Breakdown Structure. Now you figure out the number of tasks your team needs to complete. Estimate the duration of each task.
