The method divides objects to be tested into test group, determines test objective of each group, picks-up abstract test cases, and defining test steps of test cases so as to form abstract test set ATS. Based on objects and services or functions supported by EPA protocol implementation ...
If e.g. the omega-3 level or omega-3 test would be calculated, obviously also the omega-3 alpha-linolenic acid has to be included (or you redefine what you mean with omega-3 and simply ignore textbook knowledge). Thus, terms like "omega-3 level" are too broad and not appropriate whe...
