Abstract and schedule pressure. Then use the method of combining ECRS and ESIA to formulate an improvement plan: First, adjust the improved multi-round prototype test and regression test to several large rounds of tasks: initial sample test, problem verification test, positive sample test, and regression test , and for each activity, strict access conditions are imposed. The second is to add a test case review sub-process to make test cases more targeted and practical. The third is to standardize the self-test requirements to expose more product defects in the early stage. The fourth is to add a number of technical review links, so that the management of the test activities is under control. Finally, for the improved test process, the implementation planning and guarantee requirements are put forward, so that the improved test process can be implemented in the actual operation in the future. Aiming at the practical problems existing in the new product testing process of V company, the paper puts forward suggestions for improvement in line with the current new product testing process of V company. The improvement plan proposed in this paper provides a useful exploration for the new product testing process of V company and product testing in the power supply industry, and has good practical application value. 【Key Words】 testing process;process improvement;test rotation;self-test; V company 【Thesis Type】 Applied Research III 目录 1 绪论 ......................................................................................................... 1 1.1 研究背景 ........................................................................................... 1 1.2 国内外研究现状 ............................................................................... 2 1.2.1 国外研究现状 ............................................................................. 2 1.2.2 国内研究现状 .......................................................................
