Test Plan The test plan documents the process by which you are going to verify that your final design meets engineering specifications (features, functions, performance). In other words, how you are going to test the features and functions that constitute your design implementation. The structure of a test plan is often consistent with the structure utilized for engineering spec: for each spec or requirement there is a defined test method or procedure and pass/fail criteria to demonstrate compliance with the spec or requirement. The important components of a test plan are: 1. What you’ll test (and what you won’t test) 2. How you’ll test: equipment and materials needed, test configurations and procedures, pass/fail criteria 3. Responsibilities and the approval process 4. Risks and contingencies The plan should be understandable by an engineer not familiar with the project. Below is a more detailed format for a simple test plan that also incorporates placeholders for test results: 1. Overview: purpose of testing; what you’ll test; what you won’t test. 2. Tests (list or table): test # and name; test description and pass/fail or exit criteria; equipment needed and configurations; risks and contingencies; responsibility for test and for approval; schedule. 3. Traceability or verification matrix (table): specification # and brief description; system component embodying the spec (optional); test # (name optional if contained elsewhere); test date (start/stop dates may be needed), pass/fail or test result (verification); remarks or actions needed if test failed; signoff. Several specifications may utilize the same test, so duplicate entries should point to one entry which contains more detailed information. 4. Summary of test results: test log (if appropriate), successful tests, failed tests, impact and mitigation plans, responsibilities. These elements can be integrated or rearranged to match project characteristics or personal/team preferences. It may be more helpful to include traceability information (mapping of tests to specs and, if appropriate, to requirements) in the test list (#2) rather than in the verification table.

It is usually based on planning and analysis activities that have been conducted to define an “optimum” approach. The following areas should be addressed: 1. Assembly processes, especially critical at component interfaces which are common failure points. Include steps and instructions. The process references the BOM or master parts list. 2. Fabrication processes 3. Estimated resource requirements (equipment, tools, material) 4. Facilities 5. Schedule 6. Personnel requirements The plan should be understandable by an engineer not familiar with the project.
