Executing the Test Plan
The test plan should be executed as designed. If the plan cannot be executed as designed it should be changed, or notations made as to what aspects of the plan were not performed. Testing according to the test plan should commence when the project commences and conclude when the software is no longer in operation. Portions of the test plan can be performed while the test plan is being written. This category focuses on the many skills needed to carry out the test plan, like design test cases and test scripts, use test tools, execute tests, record test results, and manage defects.
