Final answer:
A test plan is the correct document to prepare before testing begins, as it includes objectives, scope, procedures, and testing parameters.
Step-by-step explanation:
Before testing begins, a Test plan with explanatory notes and data should be prepared. When drafting a proposal, it involves discussing a problem, presenting possible solutions, addressing any objections to those solutions, and concluding with a strong recommendation. This process aligns with the creation of a test plan in the business or engineering context, as a test plan outlines the strategy that will be followed to verify and ensure that a product or system meets its design specifications and other requirements. A test plan would generally include objectives, scope, procedures, and the parameters of the test, and would be created after formulating a thesis and an organization plan that gives a clear path forward for the testing process.
