Differential software testing aims at the automated generation of test inputs that reveal behavioral differences in software. The search for behavioral differences can be separated into two categories in which the analysis executes: (1) different program versions with the same input, and (2) the same program with different inputs. Therefore, detecting regression bugs in software evolution, analyzing side-channels in programs, maximizing the execution cost of a program over multiple executions, and evaluating robustness in deep neural networks (DNNs) can all be seen as instances of differential software analysis, where the goal is to generate diverging executions of program paths.

The key challenge of differential software testing is to simultaneously reason about multiple program paths, often across program variants, in an efficient way.

The existing work on the various areas of differential testing show that the single techniques come with their own disadvantages which limits the exploration space of the analysis. An efficient and effective testing approach asks for a hybrid execution setup.

Therefore, this thesis proposes the concept of Hybrid Differential Software Testing (HyDiff): a hybrid solution combining search-based testing with a systematic exploration technique. HyDiff's search-based component leverages differential fuzzing directed by differential heuristics. HyDiff’s systematic exploration is based on dynamic symbolic execution which allows to incorporate concrete inputs in its analysis.

HyDiff is evaluated based on a quantitative analysis with experiments and benchmarks in the specific application scenarios of differential testing.
