* In contrast to the systematic collection of research papers, we do not aim to present all the available CIT tools here. Our goal is to cover relatively mature, or highly competitive, tools that are public available, so that others can choose them for comparison, or base on them to build new testing techniques. This list is thus updated in a subjective manner.
