There are many problems with the original code, but it can now run correctly
Concolic testing alternates between CONCrete program execution and symbOLIC analysis to explore the execution paths of a software program and to increase code coverage. In this paper, we develop the first concolic testing approach for Deep Neural Networks (DNNs). More specifically, we utilise quantified linear arithmetic over rationals to express test requirements that have been studied in the literature, and then develop a coherent method to perform concolic testing with the aim of better coverage. Our experimental results show the effectiveness of the concolic testing approach in both achieving high coverage and finding adversarial examples.

The neural network model under tested is specified by --model and a set of raw test data should be given
by using --inputs. Some popular datasets like MNIST and CIFAR10 can be directly specified by using
--mnist-dataset and --cifar10-dataset directly. --criterion is used to choose the coverage
criterion and --norm helps select the norm metric to measure the distance between inputs. Some examples
to run DeepConcolic are in the following.
To run an MNIST model
python deepconcolic.py --model ../saved_models/mnist_complicated.h5 --mnist-data --outputs outs/
To run an CIFAR10 model
python deepconcolic.py --model ../saved_models/cifar10_complicated.h5 --cifar10-data --outputs outs/
To test a particular layer
python deepconcolic.py --model ../saved_models/cifar10_complicated.h5 --cifar10-data --outputs outs/ --layer-index 2
To run MC/DC for DNNs on the CIFAR-10 model
python deepconcolic.py --model ../saved_models/cifar10_complicated.h5 --criterion ssc --cond-ratio 0.1 --cifar10-data --outputs outs
To run MC/DC for DNNs on the VGG16 model
python deepconcolic.py --vgg16-model --inputs data/ --outputs outs --cond-ratio 0.1 --top-classes 5 --labels labels.txt --criterion ssc
To run Lipschitz Constant Testing, please refer to instructions in folder "Lipschitz Constant Testing".
