Here's a not too well-known instance of the use of $\varepsilon$ in mathematics: One somewhat well-known transformation for accelerating the convergence of a sequence is the Shanks transformation (after Daniel Shanks, who is probably more well-known for his number-theoretic contributions).
Thereâs no set way of creating a test plan, but there are common suggestions on what to include. Test plans donât need to be done a certain way, but if youâre new to writing test plans, the IEEE 829 is a good place to start. This standard for test plan documentation is used for software and system testing. It is a good âtemplateâ for writing your own test plan documents.
The test strategy must give a clear vision of what the testing team will do for the whole project for the entire duration. This document can be presented to the client, if needed. The person, who prepares this document, must be functionally strong in the product domain, with very good experience, as this is the document that is going to drive the entire team for the testing activities.
