Test Strategy - A high-level document defining the test phases to be performed and the testing within those phases for a programme. It defines the process to be followed in each project. This sets the standards for the processes, documents, activities etc. that should be followed for each project. For example, if a product is given for testing, you should decide if it is better to use black-box testing or white-box testing and if you decide to use both, when will you apply each and to which part of the software? All these details need to be specified in the Test Strategy.Project Test Plan - a document defining the test phases to be performed and the testing within those phases for a particular project.

A Test Strategy should cover more than one project and should address the following issues: An approach to testing high risk areas first, Planning for testing, How to improve the process based on previous testing, Environments/data used, Test management - Configuration management, Problem management, What Metrics are followed, Will the tests be automated and if so which tools will be used, What are the Testing Stages and Testing Methods, Post Testing Review process, Templates.

Test planning needs to start as soon as the project requirements are known. The first document that needs to be produced then is the Test Strategy/Testing Approach that sets the high level approach for testing and covers all the other elements mentioned above.
