A test plan outlines the strategy that will be used to test an application, the resources that will be used, the test environment in which testing will be performed, and the limitations of the testing and the schedule of testing activities. Typically the Quality Assurance Team Lead will be responsible for writing a Test Plan.
A test plan includes the following:
1: Introduction to the Test Plan document
2: Assumptions while testing the application
3: List of test cases included in testing the application
4: List of features to be tested
5: What sort of approach to use while testing the software
6: List of deliverables that need to be tested
7: The resources allocated for testing the application
8: Any risks involved during the testing process
9: A schedule of tasks and milestones to be achieved
