Abstract
The selection of unit-test-case is very important process in software development. This process requires the largest human resources and is highly expected to improve its productivity. There are mainly 3 types of unit-test-case selecting methods, called "C0", "C1", and "C2". This paper describes the efficiency of C1-unit-test-case. I'd like to study C1-unit-test-case method and compare its productivity improvement with that of C2, using branch patterns adopted in Structured Design.
