Test Models and Planning : Test planning and complete control over the test process are keys to successful software testing. Testing strategy should streamline product development and QA process. Development of an effective test model ensures best authentication process.
Test Strategy vs. Test Plan: Test planning document is a combination of strategy plugged with overall project plan. According to IEEE Standard 829-2008, strategy plan is a sub item of test plan. Every organization has their own standards and processes to maintain these documents. Some organizations include strategy details in test plan itself. Some organizations list strategy as a subsection in testing plan but details are separated out in different test strategy document.
