Logical Test Design

Abstract

This chapter discusses the development of a logical test design and the use of test design techniques. The logical test design is a collection of all of the logical test cases. Logical test cases define the tests on a logical level. The logical test design is based on the test base, the anticipated goal and the TRA. The aim is to create a balanced set of logical tests. “Balanced” means that the number of test cases that are defined for each function is in proportion to the complexity and the importance of the function. The distribution of test cases for each quality attribute is also carefully examined. Using the right test design techniques creates a set of logical tests that can be used to efficiently establish whether the system will contribute to the anticipated goal. The logical test design provides a balanced blueprint that is supported by the TRA. The blueprint can be used to elaborate the physical test cases.
