This test fixture design checklist covers the design elements that need to be considered when we build a custom test fixture for you. This tool helps the test engineer to organize their thoughts about what capabilities the test fixture must have. It is then easy develop to a Test Fixture Statement of Work which Test Head Engineering can use to quote your custom test fixture.
