Do Bug-Fix Types Affect Spectrum-Based Fault Localization

Finding a bug in the software is an expensive task,
however, debugging is a crucial part of the software development
life cycle. Spectrum-Based Fault Localization (SBFL) algorithms
can reduce the time spent with debugging. Despite the fact that
SBFL is a very well researched topic, there are not many tools
that implement it. Many studies have dealt with the effectiveness
of SBFL algorithms, although these have been evaluated on Java and
C++ programming languages. We performed an empirical study on
relationship between algorithms efficiency and the bug-fix types.
First we implemented three popular SBFL approaches, i.e.
Tarantula, Ochiai and DStar, then examined whether there was a
correlation/connection between the positions of the faulty methods
in the suspiciousness ranks and bug-fix types. Results show that
certain bug-fix types can be significantly differentiated from the
others (in both positive and negative direction) based on the
fault localization effectiveness of the investigated algorithms.
