The plan typically contains a detailed understanding of the eventual workflow.
A test plan documents the strategy that will be used to verify and ensure that a product or system meets its design specifications and other requirements.
Test plan document formats can be as varied as the products and organizations to which they apply.
Test methods may be determined by standards, regulatory agencies, or contractual agreement, or may have to be created new.
One outcome of a successful test plan should be a record or report of the verification of all design specifications and requirements as agreed upon by all parties.
