The test strategy is a formal description of how a software product will be tested. A test strategy is developed for all levels of testing, as required most of the time it will be a part of Test Plan however it can also be an altogether different document. The process goes on like this:

The test team analyzes the requirements, writes the test strategy and reviews the plan with the project team. The test plan may include test cases, conditions, the test environment, a list of related tasks, pass/fail criteria and risk assessment.Entry Criteria for this process:
· A description of the required hardware and software components, including test tools. This information comes from the test environment, including test tool data.
· A description of roles and responsibilities of the resources required for the test and schedule constraints. This information comes from man-hours and schedules.
· Testing methodology. This is based on known standards.
· Functional and technical requirements of the application. This information comes from requirements, change request, technical and functional design documents.
· Requirements that the system can not provide, e.g. system limitations.

Contents of Test Strategy document:
Sections in the test strategy document include:
. A description of the required hardware and software components, including test tools: This information comes from the test environment, including test tool data.
. A description of roles and responsibilities of the resources required for the test and schedule constraints: This information comes from man-hours and schedules.
. Testing methodology: This is based on known standards.
. Functional and technical requirements of the application: This information comes from requirements, change request, technical, and functional design documents.
. Requirements that the system cannot provide, e.g. system limitations. 

Exit criteria for this process:
· An approved and signed off test strategy document, test plan, including test cases.
· Testing issues requiring resolution. Usually this requires additional negotiation at the project management level.

Depending upon projects Entry and exit criterias can be different ..Let me know in case something is missing….
