Testability is a software characteristic that aims at producing systems easy to test. A testability antipattern is a factor that could affect negatively the testability of software. In this paper we compare the antipatterns at source code level and at different abstraction levels, in order to understand at which point they are introduced during the development.
Depth of Inheritance Tree (DIT) is supposed to be a factor influencing the cost of testing: test would be more expensive if DIT is large. A question is thus to know whether DIT can be used as a predictive metric to estimate the cost of testing. In this paper, we consider the cost of testing as the number of test cases required to achieve the branch coverage, which is a classical criterion for structural...
Depth of inheritance tree (DIT) is considered as a factor influencing the cost of testing. Test is supposed to be more expensive if DIT is high. This paper relates the analysis of DIT with respect to the number of methods to test in each class. Our study based on more than 1700 classes from 6 Java applications.
